Customizing authentication and handling pre and post authentication in identity cloud service

Abstract

Techniques are provided for customizing authentication and for handling pre-authentication and post-authentication plug-ins in an access management system. Users may want to access a protected resource, such as an application, and apply customizations to the protected resource. The customizations can be applied through the use of plug-ins, such as pre-authentication and post-authentication plug-ins. After it is determined that the user has permissions to apply a specified plug-in, analysis is performed to ensure that the plug-in complies with system requirements and that the criteria for implementing the plug-in has been satisfied. A browser session and control of the application can then be forwarded to the user.

Description

BACKGROUND

Cloud-based computing platforms offer significant advantages over traditional on-premises computing platforms. For instance, cloud-based computing platforms provide scalable and flexible computing resources for users and can be deployed across geographic regions that are widely spaced apart (e.g., in different countries). Cloud-based computing platforms can provide one or more categories of services, including Software as a Service (SaaS), Platform as a Service (PaaS), or Infrastructure as a Service (IaaS).

In a cloud environment, resources can be secured and protected by an identity service provider. An identity service provider can be responsible for handling, for example, authentication, authorization, single sign-on (SSO), user management, application management and audit. An identity service provider can offer flexibility and standard solutions.

In an identity system, an authentication flow, for authenticating a user, is performed in a closed-control manner. Once an identity system starts an authentication flow, the control leaves a business application until required artifacts or tokens are generated. However, these identity solutions do not provide any flexibility. Further, such identity solutions do not provide plug-in customized code as part of the login control flow so as to influence a login decision or cleanup during logout.

Further, some systems may provide pre-authentication and post-authentication control, however, such systems use back end Application Programming Interface (API) calls. Back end API calls do not provide complete control for performing login orchestration. For example, if the system would like to create a session on the user browser as part of login process or if the system would like to clear something during logout process then, it may not be possible using back end API calls. Also, the user is not given the ability to completely control a session.

BRIEF SUMMARY

The present disclosure relates to cloud computing systems, and more particularly, to techniques for customizing authentication and handling pre-authentication and post-authentication processes in an identity cloud service. Various embodiments are described herein, including methods, systems, non-transitory computer-readable storage media storing programs, code, or instructions executable by one or more processors, and the like.

Example embodiments can be configured for authentication and authorization by an identity cloud service of an identity and access management (IAM) system. An identity and access management can also be referred to as an Access Management System (AMS). The IAM can also be generally referred to as an identity system or cloud identity system.

A cloud service can include a plurality of different types of services that are provided to companies and customers over the internet. Under an IaaS cloud service model, one or more types of resources are hosted by a cloud service provider and made available to a client (e.g., an enterprise customer). Such resources can include computing resources (e.g., compute instances), networking resources (e.g., a virtual private network), storage resources (e.g., cloud-based databases), and other hardware or software resources. Resources may be provisioned for use in a tenancy associated with a particular client. Within the tenancy, the client may have secure and isolated access to the provisioned resources, and the cloud platform may provide the client with software tools for organizing, administering, or otherwise managing the provisioned resources. For instance, an enterprise client may be provided with tools for defining the scope of access privileges to resources by different groups of employees of the enterprise client.

In a distributed computing environment, such as an environment that includes a computing platform operating under an IaaS cloud service model, various entities may request access permission to protected resources. A protected resource can include a business application such as an application used to manage employees or to conduct a payment. An application can be accessed through a website or URL. A protected resource can also include a machine. The level of access can vary among entities. For instance, as indicated above, different users within a tenancy may have access privileges that depend on their user role (e.g., human resources, administrators, sales, etc.). Thus, access control can be based upon user identity. In addition to human users, entities that require access to resources may include compute instances (e.g., virtual or bare metal machines).

When a user wants to access a resource that is protected by an access management system, the access management system receives information indicating that a particular user is requesting access to a particular protected resource. The system can then execute or invoke a process flow comprising a set of operations for authenticating the particular user. If authentication of the user is successful, then a session can be created for the user. After the session is created, the user can be redirected to the protected resource (or application) via the created session and the user is given the ability to control the application.

A user may want to be able to plug-in their own code or create their own modules for a protected resource, such as an application. For example, a user may want to modify the authentication process for an application. A user can also be known as a client, customer, enterprise customer, or tenant. Plug-ins can be triggered so as to influence an authentication decision while establishing login or for cleanup during logout from an application.

A plug-in can also be referred to as a plugin, add-in, addin, add-on, or addon. A plug-in can include computer implemented instructions to add specified rules or features to processes performed by the access management system. The example embodiments are described with respect to plug-ins for an access management system in a cloud environment. However, plug-ins can be created and applied for systems other than access management system, such as on-premise enterprise systems. Plug-ins can allow users to create and apply customizations to the authentication process. A plug-in can be triggered or activated in response to specified conditions being met.

Therefore, plug-ins can be configured to trigger at various points during the process in which a protected resource is requested and accessed. For example, a plug-in may be configured to trigger after the access management system receives an indication that a user is requesting access to a particular protected resource (e.g., pre-login). A plug-in can also be configured to trigger before a session has been established for a user (e.g., pre-login) or after a session has been established for user (e.g., post-login), but before the user has logged out.

Example embodiments can provide plug-ins that can be triggered pre-login, post-login, pre-logout, or post-logout. A plug-in that is triggered “pre-login” can be triggered before creating a single sign-on session. Pre-login can occur after an access management system receives an indication that a user is requesting access to a particular protected resource, or at a point in time before a session is established. A plug-in that is triggered “post-login” can be triggered after creating a single sign-on (SSO) session. A plug-in that is triggered “pre-logout” can be triggered before clearing a single sign-on session. A plug-in that is triggered “post-logout” can be triggered after clearing a single sign-on session. Logout can also be referred to as logoff or log-off. Pre-login can also be referred to as pre-authentication or pre-login authentication. Post-login can also be referred to as post-authentication or post-login authentication.

The plug-ins can be triggered in response to an event. For example, a pre-login trigger can be triggered in response to a log-on event. A post-logon plugin can occur after an authentication phase of logging in finishes, but before the user session is actually established. A post-logout plugin can occur when a session disconnects.

These are examples of plug-ins that can be provided by a user, however, plug-ins in addition to those identified can be provided for the login process and logout process or while determining whether a user is an authorized user of the application.

Example embodiments provide users with the flexibility of customizing the authentication process for applications. Although users are granted permission to generate and implement their own plug-ins, measures are in place to prevent the user from controlling the overall code of the cloud identity system. Further, measures are also in place to prevent the plug-ins generated by the user from putting service provider computing systems (e.g., IAM) at risk, such as by preventing the plug-ins from consuming too much computing power and/or memory, etc. Measures are also placed to decrease the risk on the service provider computing system.

As discussed above, some systems may provide pre-authentication and post-authentication control, however, such systems use back end Application Programming Interface (API) calls. Back end API calls do not provide complete control for performing login orchestration. Further, some implementations require an ID associated with the system since any changes or configurations are configured based on the system, and therefore, the user is limited in configuration options.

Example embodiments address these deficiencies by providing a solution where the control is forwarded to the application to handle and participate in, for example, pre-login, post-login, post-login, and post-logout ceremonies.

Further, an example embodiment can provide the user with complete control over a user session and the browser. Since configurations are loosely coupled, the configurations are not tied to the system. For example, a user is given the ability to change user interface structures. The user can be given complete control over the user session in the browser so as to control an authentication process and apply their own configurations. Measures are put in place to ensure that the system operates correctly.

A system in accordance with some example embodiments benefits the cloud architecture where customers want to inject and trigger their piece of code in the identity system to make pre-authentication and post-authentication decisions. An example embodiment ensures that a user's customized processing and decisions are handled before the session is created or access is given.

Benefits provided by example embodiments can include the following. Example embodiments helps customers to inject their pre-login, post-login, pre-logout, and post-logout configurations. Further, example embodiments can assist users in writing their implementation and deploy the implementation on their chosen platform. Example embodiments can allow customer applications to take part in single sign-on (SSO) session creation. In example embodiments, a POST/GET call with a required input can be called to the configured endpoint. Further, the deployed service can process the incoming request and return the result as a post redirect back to the identity system. Also, an identity management system of an example embodiment can process results sent by a pre-authenticated module or a post-authenticated module which are included in the decision making. Further, example embodiments can return a risk score for adaptive authentication. The risk score can be used to compute policy decisions, such as determining whether access to the system should be avoided.

DETAILED DESCRIPTION

In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.

The present disclosure relates to cloud computing systems, and more particularly, to techniques for customizing authentication and for handling pre-authentication and post-authentication plug-ins in an identity cloud service of an access management system.

A user, such as a customer of an enterprise system, may want to write their own code or modules for handling customization during the login process for an application. Users may want to modify the predefined login process or add additional steps to the login process. For example, the user may want to create their own session instead of using an existing session with an application. Further, a user may want to create their own notifying events about pre-login, post-login, pre-logout and post-logout, or add additional authentication measures.

Example embodiments allow users to inject their own pre-authentication and post-authentication configurations. A user can write their own implementation and deploy the implementation on their chosen platform. Example embodiments ensure that the user's customized processing and decisions are addressed before the session is created or before access is given.

I. Cloud Computing Environment

FIG. 1 illustrates a simplified block diagram of an example cloud computing environment 100, in accordance with one or more embodiments.

The environment 100 includes a cloud infrastructure system 110 operated by a cloud service provider. The cloud infrastructure system 110 may include infrastructure resources 140 (e.g., hardware and/or software components configurable to provide cloud services 130 to clients of the cloud infrastructure system 110. As illustrated, the infrastructure resources can be partitioned into different client tenancies 145A-145N. Each client tenancy 145A-145N is a logical container that can contain logical resources to which the corresponding client (e.g., customer or user) has secure and private access. For example a logical resource could be a database, a load balancer, or a testing platform for testing software code.

As illustrated in FIG. 1, the cloud infrastructure system 110 may include an Identity Access Management (IAM) system 120. The Identity Access Management (IAM) system can also be known as an Access Management System (AMS), identity system, or cloud identity system.

The IAM system 120 may be configured to manage access to the infrastructure resources 140 by user principals and/or resource principals. For example, the functionality provided by the IAM system 120 may include an identity cloud service 135 (another example of cloud services 130). The cloud based identity service (e.g., identity cloud service 135) can be configured to maintain stored information about users associated with the tenancies 145A-145N, such as usernames, passwords or other credential information, user information, and the like. IAM system 120 can be implemented in hardware and/or software and may include, for example, one or more access management servers configured to process requests from client devices for access to resources within the client tenancies 145A-145N.

The IAM system 120 is configured to protect access to protected resources, such as applications. Each of the client tenancies 145A-145N can include one or more applications 155A-155N. Applications 155A-155N can correspond to business applications that are used by the client, such as human resource applications, payment applications, etc. Each of the tenants client tenancies 145A-145N can include a plurality of different applications based on their business needs. Further, each of the applications can be configured to include different authentication processes and can be configured to provide different information during the authentication process.

II. System Architecture

FIG. 2 illustrates a system architecture of a system 200, in accordance with some example embodiments. The system architecture 200 includes a user 210, a browser 220, one or more customer applications 230, the internet 240, an identity service 251, a database 252, and plug-ins 253. Identity service 251, database 252, and plug-ins 253 can make up an access management system 250 or the domain of an access management system.

A user 210, such as a customer of the access management system, may want to configure plug-ins. The user 210 can use a browser 220 on their computing device (e.g., laptop, desktop, mobile device) to request to configure and apply pre-authentication and/or post-authentication plug-ins. The user 210 can access customer applications 230 through the internet 240. The applications can include any applications that exist in the access management system and are accessible and configurable by the user. The applications that can be configured by the user can vary based on the administrator rights and permissions given to the user.

The access management system 250 can include one or more identity services 251, one or more databases 252, and plug-ins 253. Identity service 251 is an example of cloud service. Database 252 can be configured to store login actions and rules for the access management system 250. Plug-ins 253 can include pre-authentication and post-authentication plug-ins that are configured to be implemented in customer applications 230.

The system 200 exposes configurations so that the customer can configure pre-authentication and post-authentication plugins, which allow customers to create customized code.

III. Plug-Ins

An example embodiment provides for authorized use of plug-ins. A plug-in can also be referred to as a plugin, add-in, addin, add-on, addon or a plug-in extension. A plug-in can include computer implemented instructions to add specified rules or features to processes performed by the access management system. A plug-in can also be known as a trigger. A plug-in can be composed to trigger at a particular time during, for example, an authentication process. The example embodiments are described with respect to plug-ins for an access management system, in a cloud environment. However, plug-ins can be created and applied for systems other than access management system, such as on-premise enterprise systems.

Plug-ins can be used to, for example, provide notifications regarding events, to provide audit information, to provide third-party applications with information, for creating a footprint in a browser, for modifying an application session cookie, or for calculating and returning application-based business logic risk-scores.

With respect to notification regarding events, a user may want to be notified whenever a login occurs, or the user may want to be notified regarding what happened during login. Alternatively, the user may want to be notified regarding what is occurring during pre-login or post-login.

An audit can include creating an audit trail. The conditions for a plug-in are audited to determine whether the conditions for the plug-in are being met. As another example, a user may want to make an audit for a particular user accessing an application on a tenant's account.

Providing third-party applications with information may be used when a user wants to bring in a third-party authentication or another form of authentication, in addition to that which is already provided. The user may want to inform the third-party application regarding the status of the authentication.

Creating a footprint in a browser may occur when a user wants to create a footprint in the browser for a specific application, even before creating a session. Further, a user may want to calculate a score based on their environment. That is, a user may want to calculate and return application-based business logic risk-scores.

As another example, a user may want to add another level of authentication (e.g., multi-factor authentication (MFA). The user may want to add an additional authentication requirement, such as generating a token or requesting biometric information.

These are merely examples and plug-ins can be used to accomplish other tasks than those identified above.

A. Plug-In Configuration

Plug-ins can be configured to trigger at various points in time. A plug-in that is triggered “pre-login” can be triggered before creating a single sign-on session. Pre-login can occur after an access management system receives an indication that a user is requesting access to a particular protected resource, or at a point in time before a session is established. A plug-in that is triggered “post-login” can be triggered after created a single sign-on (SSO) session. A plug-in that is triggered “pre-logout” can be triggered before clearing a single sign-on session. A plug-in that is triggered “post-logout” can be triggered after clearing a single sign-on session.

In order to configure a plug-in, the user has to be an authorized user of the system. Users may have to go through multi-factor authentication (MFA) to get a token or console, so only valid users are able to configure the plugins. In order to obtain the token indicating that the user is an authorized user, the user may perform a sign on session. A user can include an administrator of a tenant in the multitenant cloud environment. A tenant can include, for example, a company or a branch within a company. Further, depending on the type of plug-in generated, the level of authorization needed can vary. That is, the type of plug-in generated can vary depending on the authorized role of the administrator.

The access management system can provide the user with attributes and values the user can change. The user will upload their public key and forward their public key to the access management system. After the user configures the plug-in, they will forward the plug-in along with their private key to the access management system. The access management system will verify the signature of the response using the public key provided by the user. Therefore, no other third parties can interfere since they do not have the private key of the user.

Plug-ins can be configured using an identity system admin console or with a token with an identity domain administrator role. When the user logs into the access management system, the user can access an administrator control which identifies permissions needed in order to generate the one or more plug-ins. If the administrator does not have the needed permissions for a particular plug-in, then the user will not be allowed to configure the particular plug-in.

A plug-in will be configured to include an application URL. The URL will correspond to the application for which the plug-in is configured. The plug-in code will also include information regarding the state of the application for implementing the plug-in, such as whether the application should be in a pre-login state, a post-login state, a pre-logout state or a post-logout state. The plug-in configuration can also include information such as whether it is mandatory or optional.

The plug-in configuration can also include information regarding security, such as any required username or password. The configuration can also include details of a service endpoint, or what kinds of signatures are needed. The level of sensitivity configured by the user can vary based on the administrator role. The plug-in will also include account information of the user. Based on the information in the plug-in, the access management system can determine whether or not user is authorized to implement the plug-in and whether the criteria for the plug-ins have been met.

The plug-in will also include the public key of the user. The access management system will verify signatures in responses using a public key to ensure that no third party factor has interfered in the response. The access management system will verify that the user is to correct user by using the public key. The plug-in can sign their responses using their private key.

Since the call for the plug-in is going out of the access management system, validation measures (e.g., private key, public key) are implemented ensure that there are no security issues. Plug-ins can also be configured to ensure that the plug-ins comply with system requirements. The plug-in is configured to ensure that security measures are maintained. For example, a plug-in is configured with a nonce so as to prevent an external request replay attack.

A replay attack can include when a third party obtains the request or transmission and fraudulently or maliciously duplicates the request one or more times. A replay attack can also occur if there is a bug in the code of the plug-in and the code sends a request multiple times to the access management system. Through the use of a nonce, a second request will be rejected, as the earlier request would have an evicted nonce. Only one response will be accepted from a plug-in in a single session. The access management system would not reply to a request if it has previously replied to a request with the identified nonce. A nonce is generated for every request so that a request cannot be duplicated. A nonce can include randomly generated numbers and/or letters that would be unique to the specific instance of the plug-in.

An example embodiment can also prevent forged requests. The identity system sets the nonce in a cookie, so that even if someone captures the nonce, they cannot succeed without the cookie containing the nonce. The cookies are set in the browser. The browser will have the corresponding data and the corresponding data has the nonce. The cookies in a browser are set for the particular domain corresponding to the plug-in. An improper user cannot forge the system because each request coming from a plug-in calls a particular domain. The nonce will be compared in the backend as well as in the cookie.

An example embodiment also ensures data integrity with respect to request data and data integrity with respect to response data. The access management system will sign the data output. The corresponding tenant's private key and the plug-in has to verify the response using the public key of the access management system.

All requests and response data can be sent in a JASON web token (JWT format), which is signed by the private key of the sender. Upon receiving the data, a recipient can be required to verify the signature using a public key of sender. With respect to request data, the identity system can sign the request data using its private key when sending to application. Upon receiving, the application can access a data store (e.g. admin/v1/SignedCertJwk) to get the public key for verification.

With respect to data integrity, after processing request data, the application builds its own data and can send the data to the identity system. The data will be signed by its private key, and the counter part of this key (i.e., public key) can already be uploaded to identity system at the time of configuring the plug-in. The identity system can verify the data sent by application using the public key of the user. The tenant will sign the response with their own private key and access management system will verify the signature using the public key uploaded for the plug-in.

Further, the access management can send a response to the plug-in using the tenant's private key. The plug-in can verify the response from the access management system using the public key of the access management system. The plug-in can request the public key of the access management system (e.g., tenant's public key for the access management system).

B. Mandatory Plug-Ins

Plug-ins that are configured to be triggered during pre-login or pre-authentication can include criteria that are identified by user as being mandatory or optional. If criteria for a plug-in is designated as mandatory, then the plug-in cannot be initiated unless all of the criteria has been met. If criteria for a plug-in is designated as optional, then all of the criteria does not need to be met before the plug-in is initiated.

A mandatory plug-in is a plug-in which has one or more factors or criteria that is required in order for the plug-in to be implemented in the current session. If factors of the plug-in are not met, the session will not be created. For example, if a plug-in is a multi-factor authentication plug-in, then the user must provide the information needed in order to implement the plug-in. However, if the plug-in is, for example, an audit plug-in, no additional information may be needed from the user since the plug-in can perform the task without requiring any additional information. Plug-ins that require additional information can be placed in the list for the pre-authentication process whereas plug-ins that do not require additional information from the user can be placed in a list of post-authentication process plug-ins.

If one or more factors or criteria for a mandatory plug-in are not satisfied, then the plug-in will not be implemented in the current session. For example, if the plug-in is for another layer of authentication, such as requesting biometric information, then the authentication process will not resume without requesting biometric information. Therefore factors for pre-login plug-ins have to be satisfied in order for the session control to be transferred to the user.

Pre-login plug-ins can, as a default, be configured to be mandatory. That is the pre-login plug-in criteria must be satisfied before the plug-in is allowed to access application since access to the application could be controlled. If the mandatory criteria is not satisfied then the one or more plug-ins including the mandatory criteria will be denied. A decision can be returned to a user denying the user access to the protected resource for that plug-in.

Post-login plug-ins may not need to be designated as mandatory as the user will not usually be prevented from logging out of an application. That is, logging out of an application will usually not be prohibited due to an error with a plug-in. Therefore, even if a post-login plug-ins fails, the user will not be prohibited from leaving an application. However, the user can be notified regarding any issues with a plug-in.

C. Optional Plug-Ins

An optional plug-in is a plug-in which has one or more factors or criteria that is not required in order for the plug-in to be implemented in a current session. If one or more factors or criteria for an optional plug-in are not satisfied, the plug-in can still be implemented in a current session with an application. Therefore, if any of the plug-ins which are optional fail, that is one or more factors or criteria for the plug-ins fail, the session can still proceed.

Plug-ins that are triggered to occur post-login can be identified as optional plug-ins. Plug-ins that are triggered to occur post-login are identified as optional because post-login plug-ins can be grouped together as a group, and therefore processed as a group. Whereas plug-ins that occur pre-login are processed individually. Therefore, if any factors are not met for post-login plug-ins a session can still be created.

Plug-in factors that can be considered optional can include application specific audit-logging plugins, application login reporting plugins, and application session tracker plugins.

IV. Plug-In Stages

A user may want to generate plug-ins to be used to during the authentication process. The authentication process can generally refer to the stages that occur before, during and after authentication of a user with an application. An example embodiment ensures that the user's customized processing and decisions are addressed before the session is created or before access is given. Therefore, before the session is created or before access is given, it is determined whether any pre-authentication or post-authentication plug-in can be applied.

Even though a session has been created after authentication, the session is created in the background and the user is not given control of the application until after the plug-ins have been evaluated. The application will not be redirected to the user to control until the plug-ins have been evaluated.

Plug-ins can be generated for various points in the process of requesting access to a particular protected resource. For example, a plug-in may be configured to trigger after the access management system receives an indication that a user is requesting access to a particular protected resource (e.g., pre-login). A plug-in can also be configured to trigger before a session has been established for a user (e.g., pre-login) or after a session has been established for user (e.g., post-login), but before the user has logged out. Therefore, a user is provided with a plurality of different possibilities for customizing plug-ins.

FIG. 3 illustrates a sequence diagram 300 of the stages during which plug-ins can be applied, in accordance with some example embodiments.

Stage 310 discloses a pre-login or pre-authentication stage. At this point, the user has not yet established a login session. That is, the user has not yet logged into an application. One or more plug-ins can be generated for implementation pre-login. The plurality of plug-ins can be stored in an ordered list. If there is more than one plug-in than the plug-ins are evaluated sequentially.

Stage 320 discloses a stage during which a session has been established.

Stage 330 illustrates a post-login stage which is also a post-authentication stage. At this point in time the user has established a login session and has been authenticated.

Stage 340 illustrates a pre-logout stage which is also a post-authentication stage. This is a stage after the user has logged in, but before the user has logged out of the application.

Stage 350 illustrates a stop session stage. At this point, the user has indicated that they would like to end their session with the application.

Stage 360 illustrates a post-logout stage, which is also a post-authentication stage. At this stage, the user has logged out of the application.

FIG. 3 illustrates example stages for which plug-ins can be configured. However, additional pre-authentication and post-authentication stages can be included other than those shown in FIG. 3.

V. Methods for Handling Customized Plug-Ins

FIG. 4 illustrates a method 400 of customizing plug-ins, in with some example embodiments.

At step 401, the access management system may receive a request to access a protected resource. The request can be received from a user (e.g., tenant) of the cloud computing environment to access a protected resource managed by the access management system, such as a business application. A user may submit a request indicating that they would like to implement a customized a plug-in. A user can customize plug-ins that will trigger pre-authentication or post-authentication.

At step 402, the access management system can determine whether the user is authorized to access the protected resource. Since the resource is a protected resource, it must be determined whether the user is an authorized user before the user is allowed to customize or modify any aspect of the business application. If the user is not authorized to access the resource, then the user will not be allowed to configure plug-ins for the resource. An authorization process can be performed with the user to ensure that the user is an authorized user. Further, the authorization process can ensure that a particular plug-in is configured within the permissions for a particular user.

The access management system can determine whether the user is authorized to access the resource by performing an identity service authentication process, such as single sign-on (SSO). If the identity service authentication process fails, then the user will not be authorized to implement any customized plug-ins. The identity service authentication process can include a challenge and response authentication. If the user fails to respond correctly to any of the challenges, then no calls will be made for any configured plug-ins.

At step 403, in response to determining that the user is authorized to access the protected resource, the access management system can identify one or more plug-ins for controlling an authentication session for the protected resource.

At step 404, the one or more plug-ins generated by the user are analyzed to determine that criteria for the one or more plug-ins are satisfied. This step can occur after creating a single sign-on session, but before redirecting to the actual application. The access management system can give a call back to plug-ins. Step 404 is explained is greater detail with respect to FIG. 5.

At step 405, in response to determining that the criteria for the one or more plug-ins are satisfied, a session can be created for the user. A session includes a period a time during which a user is given access to the application.

At step 406, the user is provided with direct access and control of the application.

FIG. 5 illustrates a method 500 of analyzing a plugin, in accordance with some example embodiments. FIG. 5 can correspond to step 404 of FIG. 4.

All of the plug-ins that the user would like to implement for a session will be generated before a session is established. An example embodiment analyzes the plug-ins to determine whether or not the plug-in can be implemented for session.

At step 501, it is determined whether there are any pre-authorization plug-ins. Pre-authorization plug-ins are plug-in to be implemented before a session is established. The plug-ins can be obtained from an ordered list. The ordered list can include one or more plug-ins that are configured for a particular application. The ordered list can be stored on a data store that is accessible by the access management system. The ordered list can include pre-authentication and post authentication plug-ins that are configured by the user.

Pre-authentication plug-ins will be processed before any post-authentication plugins in the ordered list. The first plugin in the ordered list or the plug-in in the ordered list having the highest priority can be identified as a highest ordered plug-in. A second plug-in in the ordered list having a second highest priority can be identified as a second highest ordered plug-in, and so forth for any remaining plug-ins.

At step 502, the pre-authorization plug-in is executed and a response is returned. Processing of the pre-authorization plug-in can be performed. Processing can include determining whether the criteria for implementing the plug-in have been met. For example, if there are mandatory criteria for implementing the plug in, then it is determined whether the mandatory criteria have been met. Processing can also include determining whether security measures are in place. For example, that the plug-in includes a nonce and public/or private key information.

At step 503, a cookie can be created for a browser session with the application. The cookie can be updated based on the results of processing the pre-authorization plug-in. A cookie is a file which is used to keep track of events occurring during a session. The user can refer to the cookie to determine the results of processing the plug-in for implementation.

At step 504, the access management system can determine whether there are any post-authorization plug-ins. The access management system can identify any post-authorization plug-ins from the ordered list. The post-authorization plug-ins can occur after the pre-authorization plug-ins on the ordered list.

At step 505, post-authorization plug-ins are executed and a response is returned. The post-authorization plug-in can be processed. Processing of post-authentication plug-ins would occur after all of the pre-authentication plug-ins have been processed. Processing can include determining whether the criteria for implementing the plug-in have been met.

At step 506, the cookie for the session is updated based on the results of processing the post-authorization plug-in. The cookie is updated to include information regarding the processing of the post-authentication plug in.

VI. Sequence Diagram

FIG. 6 illustrates a sequence diagram of a method 600 for customizing a plug-in, in accordance with some example embodiments.

As shown in FIG. 6, the sequence includes a browser 610, an application system 620, an identity system domain 630, and pre-authentication and post-authentication plug-in system 640. The application domain 620 can include an application gateway server 621 and one or more customer applications 622. The identity system domain 630 can include an access gateway server 631 and an identity and access management system 632.

Pre-authentication plug-in and post-authentication plug-in system 640 is configured to provide the plug-ins. The plug-ins can also be called plug-in extensions as they extend operations currently provided by the access management system. Pre-authentication plug-in and post-authentication plug-in system 640 can include a pre-authentication handler 641 and a post-authentication handler 642. The pre-authentication handler 641 can be configured to process pre-authentication or pre-login plug-ins hosted by the customer. The post-authentication handler 642 can be configured to process post-authentication or post login, pre-logout and post logout plug-ins hosted by the customer. The pre-authentication plug-in and postauthentication plug-in system 540 can be part of a customer hosted plug-in system in the cloud environment.

As illustrated in the sequence diagram shown in FIG. 6, when the cloud identity system detects configured pre-authentication or post-authentication plugins, it sends a request back to the configured URL with proper request data. The third party plugin can take action on the received input and provide a necessary result so that cloud identity system can take appropriate decisions while allowing access to the system.

A plug-in can be invoked by the access management system using a URL corresponding to that plug-in. The URL for a plug-in is configured and identified when the plug-in is registered with the access management system. Registration and generation of the plug-in can be done via a console, such as a web interface provided by a cloud services provider for making configuration changes to a customer's account. The registering of a plug-in can be performed by, for example, a user (e.g., administrator) that is designated for the customer (e.g., designated for a customer tenancy). Only an administrator with the appropriate credentials for logging onto the console can make changes to an application. Access management system can control the console that is provided to the administrator.

In the example embodiment shown in FG. 6, the steps occur in the front end or front channel and there are no backend or back channel communications.

At step 650, the user can open an application on the browser 610. The user can select an application, such as a human resources application or a payment application of the tenant, that is protected by the access management system. For example, the user can select a webpage for an application or enter a URL on a browser.

At step 651, the gateway server 621 can determine that the application that the user wants to access is a protected resource and therefore the user cannot access the application without a session cookie. The can gateway server 621 can then send a URL redirection code (e.g., 302) to request authorization to access an application. The request can performed using a method for accessing websites or applications, such as OAuth.

At step 652, the browser sends a GET request to the access gateway server 631 to request authorization. The redirect from step 651 goes back to the browser 610 and the browser 610 sends it to the access gateway server 631. The access gateway server 631 can determine whether the application, for which access is requested, is a protected resource.

At step 653, the access gateway server 631 forwards the GET request to the identity and access management system 632. After the access gateway server 631 determines that the application is a protected application, the call is redirected to the identity and access management system 632. The call is redirected to the identity and access management system 632 since the access gateway server 631 can identify that it does not have a cookie for the session.

At step 654, the authorization ceremony is started. Primary authorization or primary authentication is performed such as requiring a user name and password. Primary authorization can include implementing multifactor authentication (MFA) policies, Terms of Use (ToU) policies, etc. The primary authentication value using the password and any multi-factor authentication is performed so as to initiate the process of allowing the user to access the application.

If there are no plug-ins, then the process can proceed to cookie creation. However, if there are plug-ins, then the method proceeds to step 655.

Authorization is shown as occurring at step 654 after the GET authorization is sent by the access gateway server 631 to the identity and access management system 632. That is, this is performed before the login and password page is presented to the user. However, the authorization process can instead occur after the user name and password have been verified (step 667), that is after the user has entered their login and password.

At step 655, a check is performed to determine whether pre-authentication plug-ins have been configured. The plug-ins can be obtained from one or more databases of the tenant that act as microservices to the access management system.

Steps 655 and 668 are explained in greater detail with respect to FIGS. 11A and 11B.

At step 656, the identity and access management system 632 with forward the pre-authentication plug-in to the access gateway server 631. The access management system 632 will send an OK and forward pre-authentication to the access gateway server 631 of the identity system domain 630.

At step 657, the access gateway server 631 will forward the pre-authentication plug-in to the browser 610. The access gateway server 631 will forward an OK and pre-authentication information to the browser 610.

At step 658, the browser 610 will forward the pre-authentication plug-in to the pre-authentication handler 641 for execution. The browser 610 will send a POST execute pre-authentication call to the pre-authentication handler 641.

At step 659, the pre-authentication handler 641 will process the pre-authentication. The pre-authentication and post authentication system 540 can be part of a customer hosted plug-in system in their tenancy.

At step 660, the pre-authentication handler 641 will return a pre-authentication result to the browser 610. For example, if the plug-in is a mandatory plug in, it will determine whether the criteria for the plug-in has been met.

At step 661, the browser 610 forward the pre-authentication result to the access gateway server 631. That is, the browser 610 will send a POST pre-authentication result to the access gateway server 631.

At step 662, the access management system 632 will receive the pre-authentication result information and take any actions associated with the result. For example, if the plug-in includes factors that are mandatory and the factors were not met, then the flow will not proceed. However, if the plug-in evaluation does not result in errors, then it can proceed to step 663.

At step 663, the identity and access management system 632 will send the login page to the access gateway server 631.

At step 664, the access gateway server 631 will forward the login page to the browser 610.

At step 665, after the browser 610 has received a user name and password via the login page, the browser will forward the user name and password to the access gateway server 631. The browser can send a POST call forwarding the username and password to the access gateway server 631.

At step 666, the access gateway server 631 will forward the user name and password to the identity and access management system 632. The user name and password can be forwarded via a POST call to the identity and access management system 632.

At step 667, the identity and access management system 632 will verify the username and password. After the user name and password is verified, a session can be established for the user and a session cookie is generated.

At step 668, a check is performed to determine whether any post-authentication plug-ins have been configured.

At step 669, the identity and access management system 632 will forward the post-authentication plug in to the access gateway server 631.

At step 670, the access gateway server 631 will forward the post-authentication plug-in to the browser 610.

At step 671, the browser 610 will forward the post-authentication plug-in to the post-authentication handler in order to execute or invoke the post-authentication plugin.

At step 672, the post-authentication handler 642 will execute or invoke the post-authentication plug-in.

At step 673, the post-authentication handler 642 will forward the post-authentication plug-in processing results along with a session cookie for the user's browser session.

At step 674, the browser 610 will forward the post-authentication plug-in results to the access gateway server 631.

At step 675, the access gateway will forward the post-authentication plug-in result to the identity and access management system 632.

At step 676, the identity and authentication component will compute post-authentication actions, if any. Post authentication actions can be defined using a post authentication plugin sequence. If there are plugins present, then the plug-ins include post-authentication actions to be completed.

At step 677, the session cookie is sent to the to the access gateway server 631. The identity and access management system 632 will forward a session cookie and an authorization code to the access gateway server 631. An authorization code can include an opaque token containing information used by system to grant an access token (e.g., used for access token exchange). An authorization code can include an OpenID Connect (OIDC) authorization code.

At step 678, the access gateway server 631 will forward the session cookie and an authorization code to the browser 610.

At step 679, the browser will forward the authorization code and token ID to the gateway server 621 of the application.

At step 680, the gateway server 621 of the application will evaluate the authorization and ID token and create a session.

At step 681, the gateway server 621 will send the application and session cookie to the browser 610.

At step 682, the browser 610 will send a GET command for the application to the application gateway server 621.

At step 683, the application gateway server 621 will forward the GET command for the application to the application 622

At step 684, the application 622 will send an application console to the gateway server 621.

At step 685, the gateway server 621 will provide application access to the browser 610. The user is given access to the protected resource, such as a business application.

A. Request Format

An example embodiment can allow a user to configure pre-authentication and post-authentication plug-ins. The system can send requests (i.e., POST request) and provide responses (i.e., POST response) throughout the process of handling the pre-authentication and post authentication plugins.

FIG. 7 illustrates a request format of a request 700 used in handling plug-ins, in accordance with some example embodiments.

As shown in FIG. 7, the request 700 can include a plugin-ID 710, a nonce 720, a redirect URL 730 and a data structure 740.

A plugin-ID 710 can be used to identify a plug-in from other plug-ins. A plug-in ID can be an alphanumeric identifier or a name for the plug-in.

A nonce 720 is included to provide, for example, security measures. A nonce can include randomly generated numbers and/or letters. An external request replay attack can be prevented by having a nonce with each request. A second request will be rejected, as the earlier request would have an evicted nonce. A nonce is generated for every request so that a request cannot be duplicated.

A redirect URL 730 will be a URL of the access management system and is used to redirect to the application page.

Data structure 740 can include data structures to indicate the request. Data can be sent as a JWT token signed by a tenant key. A JWT can contain any information that would be useful or relevant to the client. Further, the format of the JWT can vary based on the desired information for the token.

B. Response Format

FIG. 8 illustrates a response format of a response 800 used in handling plug-ins, in accordance with some example embodiments.

As shown in FIG. 8, the response 800 can include a plug-in ID 810, a nonce 820, a status of execution 830, and a data structure 840.

A plugin-ID 810 can be used to identify a plug-in from other plug-ins. A plug-in ID can be an alphanumeric identifier or a name for the plug-in.

A nonce 820 is included to provide, for example, security measures. A nonce can include randomly generated numbers and/or letters. An external request replay attack can be prevented by having a nonce with each request. A second request will be rejected, as the earlier request would have an evicted nonce. A nonce is generated for every request so that a request cannot be duplicated.

A status of execution 830 can indicate the processing status of a plug-in.

A data structure 840 can include data structures to indicate the response. Data can be sent as a JWT token signed by a tenant key.

C. Plug-In System and Method

FIG. 9 illustrates a simplified block diagram of an identity and access management system 900 including a plug-in system 910, in accordance with some example embodiments.

The identity and access management system (IAM) 900 can include a plug-in system 910 for identifying and analyzing plug-ins. The plug-in system 910 can include a pre-authentication identification sub-system 911, a post-authentication identification sub-system 912 and an analysis sub-system 920. The analysis sub-system 920 can include execution sub-system 921 and post execution sub-system 922. The plug-in system 910 can include one or more processors and memories for each of the sub-systems.

FIG. 10 illustrates an overview of method 1000 of applying plug-ins, in accordance with some example embodiments. The steps shown in FIG. 10 are explained in greater detail with respect to FIGS. 11A and 11B.

At step 1010, the plug-ins to be analyzed are identified. This includes identifying pre-authentication and post-authentication plug-ins. For example, any pre-login, post-login, pre-logout and post-logout plug-ins are identified. All of the plug-ins to be implemented for an application are identified prior to initiating the analyzing of the plug-ins. This step can be performed by, for example, the pre-authentication identification sub-system 911 and the post-authentication identification sub-system 912 of FIG. 9.

At step 1020, the execute stage can be performed. This step can be performed by, for example, the execution sub-system 921 of FIG. 9. The execute stage will prepare the data for the plugin or the browser can sign the data using a current private key to generate a nonce and store it in the back end. Various actions can be performed to prepare the plug-in. Further, the request to be sent to the browser can be prepared.

At step 1030, the post execute stage can be performed. This can be performed by, for example, the post execution sub-system 922 of FIG. 9. The POST execute will return a plug-in result and verifies the that the plug-in can operate correctly.

D. Plug-In Processing

FIGS. 11A and 11B illustrates a flow diagram of a method 1100 for handling pre-login plug-ins, in accordance with some example embodiments.

In the example shown in FIGS. 11A and 11B, pre-login plug-ins are analyzed. Similar processing can be performed for post authentication or post-login plugins. However, the processing needed for post authentication plug-ins may include fewer steps since the post-login plug-ins will often be optional and not mandatory. Post-authentication plug-ins maybe be identified as optional since a user is often not prohibited from logging out of an application due to issues with plug-ins.

If a pre-login plug-in that is identified as a mandatory plug-in is not successful, then the process will not continue. For example, if there are three plug-ins in ordered list and the first plug-in that is being evaluated fails, then the process does not evaluate the second and third pre-login plug-ins. The ordered list can include plug-ins for all of the phases including plug-ins to be invoked during pre-authentication and post-authentication.

In an example embodiment, only one plug-in is handled at a time since the browser can often only handle one redirect at a time. Therefore, the plug-ins are handled sequentially. Plug-ins are directed to the user for handling after the session is created, but before the user is redirected to the actual resource

Alternative embodiments can include a plug-in list which does not require a specified order or a sequential order. An alternative embodiment can include a plug-in list which does not require that all of the plug-ins in the list be satisfied in order for the one or more plug-ins in the list be implemented. For example, plug-ins can be handled in parallel and asynchronously. However, the example embodiment discussed with respect to FIGS. 11A and 11B are directed to an ordered list of plug-ins which are handled synchronously.

At step 1110, pre-login plug-ins are identified (e.g., primary authentication, MFA, browser response, etc.). A request can be sent for a cookie including plug-in information for plug-ins to be implemented. The request can be sent from the browser to the access management system. As shown in FIG. 11A, three plug-ins are identified. The three plug-ins will be handled sequentially. Therefore, the primary authentication plug-in will be handled, followed by the multifactor authentication plug-in and lastly, the browser response plug-in.

At step 1111, a plug-in ID is obtained for the first plug-in (e.g., primary authentication plug-in). A plug-in ID can also be known as a trigger ID. The plug-in ID is obtained from the request cookie. The plug-in ID is used to identify the plug-in from the remaining plug-ins to be processed and keeps track of which plug-ins have been processed.

An example embodiment uses a stateless protocol. Therefore, instead of maintaining information in a database, the information is maintained in the cookie. Information between the plug-in and the access management system can be exchanged with information being maintained in the cookie. The state information is stored on the cookie and can keep track of the plug-ins that have been processed. The cookie is used by the access management system to determine the results of the processing for each of the pre-login plug-ins.

At step 1112, the analysis starts for the first plug-in (e.g., first plug-in ID=“1”).

At step 1113, it is determined whether the plug-in ID is available in the ordered list. The plug-ins can be ordered in the ordered list based on priority. The ordered list can be created by the user or can be automatically set by the access management system based on the type of plug-in. For example, the ordered list can be automatically created by the access management system based on the type of plug-in. For example, a type associated with the plug-in can identify its priority level with respect to other plug-ins.

The plug-ins are in an ordered list since the plug-ins are processed sequentially. For example, the criteria for a first plug-in in ordered list should be satisfied before considering a second plug-in on the ordered list, and a second plug-in on the ordered this should be satisfied before considering the third plug-in on the ordered list. If the first plug-in in the ordered list is not satisfied, then the process will not evaluate the second and third plug-ins. Therefore, the plug-ins are analyzed sequentially and in a specified order. The plug-ins are handled synchronously. The order of the plug-ins can be based on the identifier of the plug-in. Further, the order of the plug-ins can be based on the action that the plug-in is to perform.

If, at step 1113, the plug-in ID is not available in ordered list, the method returns to step 1110, and the next plug-in is obtained. That is, for example, the multifactor authentication plug-in will then be handled.

If, at step 1113, the plug-in ID is available in ordered list, at step 1114, the plug-in is obtained from the ordered list. The first plug-in from the ordered list is obtained. Plug-in ID “1” is obtained, which indicates this is the first plug-in in the ordered list.

At step 1115, it is determined whether the plug-in has completed the execute stage, which is the first stage. The plug-in will be processed through an execute stage (e.g., first stage) and a POST execute stage (e.g., second stage). If the plug-in has completed the execute stage it will proceed to the POST execute stage.

If the plug-in has not completed the first stage, at step 1116 a call to execute is placed. This will prepare the data for that plugin or it will sign the data using a current private key to generate a nonce and store it in the back end. Various actions can be performed to prepare the plug-in. The request to be sent to the browser can also be prepared. Step 1116 can correspond to step 1020 of FIG. 10.

If the plug-in has completed the first stage, at step 1117 a call is made to POST execute. The POST execute will return a plug-in result and verifies the that the plug-in can operate correctly. Step 1117 can correspond to step 1030 of FIG. 10.

At step 1118, it is determined whether the plug-in has a response.

If the plug-in has a response, at step 1119, the request cookie is updated with the plug-in ID.

At step 1120, a response is sent to the browser and the method returns to step 1110 to handle the next plug-in.

If at step 1118, the plug-in does not have a response, at step 1121, it is determined whether there is an exception to receiving a response An exception can include a code issue or an internal coding issue. For example, an application may be expecting a specific response, but the data provided is something different than expected and the application cannot handle the response.

If there is an exception, at step 1122, it is determined whether the exception is mandatory.

If the exception is mandatory then an error response is sent to the browser at step 1120. The browser is notified that there was an error in processing the plug-in.

If at step 1121, it is determined that there is no exception, the client application completes its actions and returns back to the service.

If, at step 1122, the exception is not mandatory the the method proceeds to step 1123.

At step 1123, the plug-in ID is incremented so as to process the next sequential plug-in in the ordered list. After updateding the plug-in ID, the process returns to step 1111 where the next plug-in ID (e.g., ID “2”) is requested for processing.

The method is described with respect to three plug-ins however, more than three or less than three triggers can be processed. For example, there may be an upper limit of plug-ins to analyze. In an example embodiment, there may be a maximum number (e.g., 4 or 5) of plug-ins that can be customized by the user.

Example embodiments allow a user to make configurations to a protected resource. The configuration is not limited to a single entity, such as the access management system provider.

As indicated above, example embodiments provide many technological improvements. System processes allow for giving the user control of implementing plug-ins. For example, during login, the user can specify the additional or alternative authentication methods (e.g., additional levels of authentication). In addition, during logout, control is given to the user to perform. Therefore, the user can perform logging out of all of the plug-ins and perform any needed cleanup. Thereby ensuring that sessions are cleared property and plug-ins are cleared properly.

VII. Example Infrastructure as a Service Architectures

As noted above, infrastructure as a service (IaaS) is one particular type of cloud computing. IaaS can be configured to provide virtualized computing resources over a public network (e.g., the Internet). In an IaaS model, a cloud computing provider can host the infrastructure components (e.g., servers, storage devices, network nodes (e.g., hardware), deployment software, platform virtualization (e.g., a hypervisor layer), or the like). In some cases, an IaaS provider may also supply a variety of services to accompany those infrastructure components (e.g., billing, monitoring, logging, security, load balancing and clustering, etc.). Thus, as these services may be policy-driven, IaaS users may be able to implement policies to drive load balancing to maintain application availability and performance.

In some instances, IaaS customers may access resources and services through a wide area network (WAN), such as the Internet, and can use the cloud provider's services to install the remaining elements of an application stack. For example, the user can log in to the IaaS platform to create virtual machines (VMs), install operating systems (OSs) on each VM, deploy middleware such as databases, create storage buckets for workloads and backups, and even install enterprise software into that VM. Customers can then use the provider's services to perform various functions, including balancing network traffic, troubleshooting application issues, monitoring performance, managing disaster recovery, etc.

In most cases, a cloud computing model will require the participation of a cloud provider. The cloud provider may, but need not be, a third-party service that specializes in providing (e.g., offering, renting, selling) IaaS. An entity might also opt to deploy a private cloud, becoming its own provider of infrastructure services.

In some examples, IaaS deployment is the process of putting a new application, or a new version of an application, onto a prepared application server or the like. It may also include the process of preparing the server (e.g., installing libraries, daemons, etc.). This is often managed by the cloud provider, below the hypervisor layer (e.g., the servers, storage, network hardware, and virtualization). Thus, the customer may be responsible for handling (OS), middleware, and/or application deployment (e.g., on self-service virtual machines (e.g., that can be spun up on demand) or the like.

In some examples, IaaS provisioning may refer to acquiring computers or virtual hosts for use, and even installing needed libraries or services on them. In most cases, deployment does not include provisioning, and the provisioning may need to be performed first.

In some cases, there are two different problems for IaaS provisioning. First, there is the initial challenge of provisioning the initial set of infrastructure before anything is running. Second, there is the challenge of evolving the existing infrastructure (e.g., adding new services, changing services, removing services, etc.) once everything has been provisioned. In some cases, these two challenges may be addressed by enabling the configuration of the infrastructure to be defined declaratively. In other words, the infrastructure (e.g., what components are needed and how they interact) can be defined by one or more configuration files. Thus, the overall topology of the infrastructure (e.g., what resources depend on which, and how they each work together) can be described declaratively. In some instances, once the topology is defined, a workflow can be generated that creates and/or manages the different components described in the configuration files.

In some examples, an infrastructure may have many interconnected elements. For example, there may be one or more virtual private clouds (VPCs) (e.g., a potentially on-demand pool of configurable and/or shared computing resources), also known as a core network. In some examples, there may also be one or more security group rules provisioned to define how the security of the network will be set up and one or more virtual machines (VMs). Other infrastructure elements may also be provisioned, such as a load balancer, a database, or the like. As more and more infrastructure elements are desired and/or added, the infrastructure may incrementally evolve.

In some instances, continuous deployment techniques may be employed to enable deployment of infrastructure code across various virtual computing environments. Additionally, the described techniques can enable infrastructure management within these environments. In some examples, service teams can write code that is desired to be deployed to one or more, but often many, different production environments (e.g., across various different geographic locations, sometimes spanning the entire world). However, in some examples, the infrastructure on which the code will be deployed must first be set up. In some instances, the provisioning can be done manually, a provisioning tool may be utilized to provision the resources, and/or deployment tools may be utilized to deploy the code once the infrastructure is provisioned.

FIG. 12 is a block diagram 1200 illustrating an example pattern of an IaaS architecture, according to at least one embodiment. Service operators 1202 can be communicatively coupled to a secure host tenancy 1204 that can include a virtual cloud network (VCN) 1206 and a secure host subnet 1208. In some examples, the service operators 1202 may be using one or more client computing devices, which may be portable handheld devices (e.g., an iPhone®, cellular telephone, an iPad®, computing tablet, a personal digital assistant (PDA)) or wearable devices (e.g., a Google Glass® head mounted display), running software such as Microsoft Windows Mobile®, and/or a variety of mobile operating systems such as iOS, Windows Phone, Android, BlackBerry 8, Palm OS, and the like, and being Internet, e-mail, short message service (SMS), Blackberry®, or other communication protocol enabled. Alternatively, the client computing devices can be general purpose personal computers including, by way of example, personal computers and/or laptop computers running various versions of Microsoft Windows®, Apple Macintosh®, and/or Linux operating systems. The client computing devices can be workstation computers running any of a variety of commercially-available UNIX® or UNIX-like operating systems, including without limitation the variety of GNU/Linux operating systems, such as for example, Google Chrome OS. Alternatively, or in addition, client computing devices may be any other electronic device, such as a thin-client computer, an Internet-enabled gaming system (e.g., a Microsoft Xbox gaming console with or without a Kinect® gesture input device), and/or a personal messaging device, capable of communicating over a network that can access the VCN 1206 and/or the Internet.

The VCN 1206 can include a local peering gateway (LPG) 1210 that can be communicatively coupled to a secure shell (SSH) VCN 1212 via an LPG 1210 contained in the SSH VCN 1212. The SSH VCN 1212 can include an SSH subnet 1214, and the SSH VCN 1212 can be communicatively coupled to a control plane VCN 1216 via the LPG 1210 contained in the control plane VCN 1216. Also, the SSH VCN 1212 can be communicatively coupled to a data plane VCN 1218 via an LPG 1210. The control plane VCN 1216 and the data plane VCN 1218 can be contained in a service tenancy 1219 that can be owned and/or operated by the IaaS provider.

The control plane VCN 1216 can include a control plane demilitarized zone (DMZ) tier 1220 that acts as a perimeter network (e.g., portions of a corporate network between the corporate intranet and external networks). The DMZ-based servers may have restricted responsibilities and help keep security breaches contained. Additionally, the DMZ tier 1220 can include one or more load balancer (LB) subnet(s) 1222, a control plane app tier 1224 that can include app subnet(s) 1226, a control plane data tier 1228 that can include database (DB) subnet(s) 1230 (e.g., frontend DB subnet(s) and/or backend DB subnet(s)). The LB subnet(s) 1222 contained in the control plane DMZ tier 1220 can be communicatively coupled to the app subnet(s) 1226 contained in the control plane app tier 1224 and an Internet gateway 1234 that can be contained in the control plane VCN 1216, and the app subnet(s) 1226 can be communicatively coupled to the DB subnet(s) 1230 contained in the control plane data tier 1228 and a service gateway 1236 and a network address translation (NAT) gateway 1238. The control plane VCN 1216 can include the service gateway 1236 and the NAT gateway 1238.

The control plane VCN 1216 can include a data plane mirror app tier 1240 that can include app subnet(s) 1226. The app subnet(s) 1226 contained in the data plane mirror app tier 1240 can include a virtual network interface controller (VNIC) 1242 that can execute a compute instance 1244. The compute instance 1244 can communicatively couple the app subnet(s) 1226 of the data plane mirror app tier 1240 to app subnet(s) 1226 that can be contained in a data plane app tier 1246.

The data plane VCN 1218 can include the data plane app tier 1246, a data plane DMZ tier 1248, and a data plane data tier 1250. The data plane DMZ tier 1248 can include LB subnet(s) 1222 that can be communicatively coupled to the app subnet(s) 1226 of the data plane app tier 1246 and the Internet gateway 1234 of the data plane VCN 1218. The app subnet(s) 1226 can be communicatively coupled to the service gateway 1236 of the data plane VCN 1218 and the NAT gateway 1238 of the data plane VCN 1218. The data plane data tier 1250 can also include the DB subnet(s) 1230 that can be communicatively coupled to the app subnet(s) 1226 of the data plane app tier 1246.

The Internet gateway 1234 of the control plane VCN 1216 and of the data plane VCN 1218 can be communicatively coupled to a metadata management service 1252 that can be communicatively coupled to public Internet 1254. Public Internet 1254 can be communicatively coupled to the NAT gateway 1238 of the control plane VCN 1216 and of the data plane VCN 1218. The service gateway 1236 of the control plane VCN 1216 and of the data plane VCN 1218 can be communicatively couple to cloud services 1256.

In some examples, the service gateway 1236 of the control plane VCN 1216 or of the data plan VCN 1218 can make application programming interface (API) calls to cloud services 1256 without going through public Internet 1254. The API calls to cloud services 1256 from the service gateway 1236 can be one-way: the service gateway 1236 can make API calls to cloud services 1256, and cloud services 1256 can send requested data to the service gateway 1236. But, cloud services 1256 may not initiate API calls to the service gateway 1236.

In some examples, the secure host tenancy 1204 can be directly connected to the service tenancy 1219, which may be otherwise isolated. The secure host subnet 1208 can communicate with the SSH subnet 1214 through an LPG 1210 that may enable two-way communication over an otherwise isolated system. Connecting the secure host subnet 1208 to the SSH subnet 1214 may give the secure host subnet 1208 access to other entities within the service tenancy 1219.

The control plane VCN 1216 may allow users of the service tenancy 1219 to set up or otherwise provision desired resources. Desired resources provisioned in the control plane VCN 1216 may be deployed or otherwise used in the data plane VCN 1218. In some examples, the control plane VCN 1216 can be isolated from the data plane VCN 1218, and the data plane mirror app tier 1240 of the control plane VCN 1216 can communicate with the data plane app tier 1246 of the data plane VCN 1218 via VNICs 1242 that can be contained in the data plane mirror app tier 1240 and the data plane app tier 1246.

In some examples, users of the system, or customers, can make requests, for example create, read, update, or delete (CRUD) operations, through public Internet 1254 that can communicate the requests to the metadata management service 1252. The metadata management service 1252 can communicate the request to the control plane VCN 1216 through the Internet gateway 1234. The request can be received by the LB subnet(s) 1222 contained in the control plane DMZ tier 1220. The LB subnet(s) 1222 may determine that the request is valid, and in response to this determination, the LB subnet(s) 1222 can transmit the request to app subnet(s) 1226 contained in the control plane app tier 1224. If the request is validated and requires a call to public Internet 1254, the call to public Internet 1254 may be transmitted to the NAT gateway 1238 that can make the call to public Internet 1254. Memory that may be desired to be stored by the request can be stored in the DB subnet(s) 1230.

In some examples, the data plane mirror app tier 1240 can facilitate direct communication between the control plane VCN 1216 and the data plane VCN 1218. For example, changes, updates, or other suitable modifications to configuration may be desired to be applied to the resources contained in the data plane VCN 1218. Via a VNIC 1242, the control plane VCN 1216 can directly communicate with, and can thereby execute the changes, updates, or other suitable modifications to configuration to, resources contained in the data plane VCN 1218.

In some embodiments, the control plane VCN 1216 and the data plane VCN 1218 can be contained in the service tenancy 1219. In this case, the user, or the customer, of the system may not own or operate either the control plane VCN 1216 or the data plane VCN 1218. Instead, the IaaS provider may own or operate the control plane VCN 1216 and the data plane VCN 1218, both of which may be contained in the service tenancy 1219. This embodiment can enable isolation of networks that may prevent users or customers from interacting with other users', or other customers', resources. Also, this embodiment may allow users or customers of the system to store databases privately without needing to rely on public Internet 1254, which may not have a desired level of security, for storage.

In other embodiments, the LB subnet(s) 1222 contained in the control plane VCN 1216 can be configured to receive a signal from the service gateway 1236. In this embodiment, the control plane VCN 1216 and the data plane VCN 1218 may be configured to be called by a customer of the IaaS provider without calling public Internet 1254. Customers of the IaaS provider may desire this embodiment since database(s) that the customers use may be controlled by the IaaS provider and may be stored on the service tenancy 1219, which may be isolated from public Internet 1254.

FIG. 13 is a block diagram 1300 illustrating another example pattern of an IaaS architecture, according to at least one embodiment. Service operators 1302 (e.g. service operators 1202 of FIG. 12) can be communicatively coupled to a secure host tenancy 1304 (e.g. the secure host tenancy 1204 of FIG. 12) that can include a virtual cloud network (VCN) 1306 (e.g. the VCN 1206 of FIG. 12) and a secure host subnet 1308 (e.g. the secure host subnet 1208 of FIG. 12). The VCN 1306 can include a local peering gateway (LPG) 1310 (e.g. the LPG 1210 of FIG. 12) that can be communicatively coupled to a secure shell (SSH) VCN 1312 (e.g. the SSH VCN 1212 of FIG. 12) via an LPG 1210 contained in the SSH VCN 1312. The SSH VCN 1312 can include an SSH subnet 1314 (e.g. the SSH subnet 1214 of FIG. 12), and the SSH VCN 1312 can be communicatively coupled to a control plane VCN 1316 (e.g. the control plane VCN 1216 of FIG. 12) via an LPG 1310 contained in the control plane VCN 1316. The control plane VCN 1316 can be contained in a service tenancy 1319 (e.g. the service tenancy 1219 of FIG. 12), and the data plane VCN 1318 (e.g. the data plane VCN 1218 of FIG. 12) can be contained in a customer tenancy 1321 that may be owned or operated by users, or customers, of the system.

The control plane VCN 1316 can include a control plane DMZ tier 1320 (e.g. the control plane DMZ tier 1220 of FIG. 12) that can include LB subnet(s) 1322 (e.g. LB subnet(s) 1222 of FIG. 12), a control plane app tier 1324 (e.g. the control plane app tier 1224 of FIG. 12) that can include app subnet(s) 1326 (e.g. app subnet(s) 1226 of FIG. 12), a control plane data tier 1328 (e.g. the control plane data tier 1228 of FIG. 12) that can include database (DB) subnet(s) 1330 (e.g. similar to DB subnet(s) 1230 of FIG. 12). The LB subnet(s) 1322 contained in the control plane DMZ tier 1320 can be communicatively coupled to the app subnet(s) 1326 contained in the control plane app tier 1324 and an Internet gateway 1334 (e.g. the Internet gateway 1234 of FIG. 12) that can be contained in the control plane VCN 1316, and the app subnet(s) 1326 can be communicatively coupled to the DB subnet(s) 1330 contained in the control plane data tier 1328 and a service gateway 1336 (e.g. the service gateway of FIG. 12) and a network address translation (NAT) gateway 1338 (e.g. the NAT gateway 1238 of FIG. 12). The control plane VCN 1316 can include the service gateway 1336 and the NAT gateway 1338.

The control plane VCN 1316 can include a data plane mirror app tier 1340 (e.g. the data plane mirror app tier 1240 of FIG. 12) that can include app subnet(s) 1326. The app subnet(s) 1326 contained in the data plane mirror app tier 1340 can include a virtual network interface controller (VNIC) 1342 (e.g. the VNIC of 1242) that can execute a compute instance 1344 (e.g. similar to the compute instance 1244 of FIG. 12). The compute instance 1344 can facilitate communication between the app subnet(s) 1326 of the data plane mirror app tier 1340 and the app subnet(s) 1326 that can be contained in a data plane app tier 1346 (e.g. the data plane app tier 1246 of FIG. 12) via the VNIC 1342 contained in the data plane mirror app tier 1340 and the VNIC 1342 contained in the data plan app tier 1346.

The Internet gateway 1334 contained in the control plane VCN 1316 can be communicatively coupled to a metadata management service 1352 (e.g. the metadata management service 1252 of FIG. 12) that can be communicatively coupled to public Internet 1354 (e.g. public Internet 1254 of FIG. 12). Public Internet 1354 can be communicatively coupled to the NAT gateway 1338 contained in the control plane VCN 1316. The service gateway 1336 contained in the control plane VCN 1316 can be communicatively couple to cloud services 1356 (e.g. cloud services 1256 of FIG. 12).

In some examples, the data plane VCN 1318 can be contained in the customer tenancy 1321. In this case, the IaaS provider may provide the control plane VCN 1316 for each customer, and the IaaS provider may, for each customer, set up a unique compute instance 1344 that is contained in the service tenancy 1319. Each compute instance 1344 may allow communication between the control plane VCN 1316, contained in the service tenancy 1319, and the data plane VCN 1318 that is contained in the customer tenancy 1321. The compute instance 1344 may allow resources, that are provisioned in the control plane VCN 1316 that is contained in the service tenancy 1319, to be deployed or otherwise used in the data plane VCN 1318 that is contained in the customer tenancy 1321.

In other examples, the customer of the IaaS provider may have databases that live in the customer tenancy 1321. In this example, the control plane VCN 1316 can include the data plane mirror app tier 1340 that can include app subnet(s) 1326. The data plane mirror app tier 1340 can reside in the data plane VCN 1318, but the data plane mirror app tier 1340 may not live in the data plane VCN 1318. That is, the data plane mirror app tier 1340 may have access to the customer tenancy 1321, but the data plane mirror app tier 1340 may not exist in the data plane VCN 1318 or be owned or operated by the customer of the IaaS provider. The data plane mirror app tier 1340 may be configured to make calls to the data plane VCN 1318 but may not be configured to make calls to any entity contained in the control plane VCN 1316. The customer may desire to deploy or otherwise use resources in the data plane VCN 1318 that are provisioned in the control plane VCN 1316, and the data plane mirror app tier 1340 can facilitate the desired deployment, or other usage of resources, of the customer.

In some embodiments, the customer of the IaaS provider can apply filters to the data plane VCN 1318. In this embodiment, the customer can determine what the data plane VCN 1318 can access, and the customer may restrict access to public Internet 1354 from the data plane VCN 1318. The IaaS provider may not be able to apply filters or otherwise control access of the data plane VCN 1318 to any outside networks or databases. Applying filters and controls by the customer onto the data plane VCN 1318, contained in the customer tenancy 1321, can help isolate the data plane VCN 1318 from other customers and from public Internet 1354.

In some embodiments, cloud services 1356 can be called by the service gateway 1336 to access services that may not exist on public Internet 1354, on the control plane VCN 1316, or on the data plane VCN 1318. The connection between cloud services 1356 and the control plane VCN 1316 or the data plane VCN 1318 may not be live or continuous. Cloud services 1356 may exist on a different network owned or operated by the IaaS provider. Cloud services 1356 may be configured to receive calls from the service gateway 1336 and may be configured to not receive calls from public Internet 1354. Some cloud services 1356 may be isolated from other cloud services 1356, and the control plane VCN 1316 may be isolated from cloud services 1356 that may not be in the same region as the control plane VCN 1316. For example, the control plane VCN 1316 may be located in “Region 1,” and cloud service “Deployment 12,” may be located in Region 1 and in “Region 2.” If a call to Deployment 12 is made by the service gateway 1336 contained in the control plane VCN 1316 located in Region 1, the call may be transmitted to Deployment 12 in Region 1. In this example, the control plane VCN 1316, or Deployment 12 in Region 1, may not be communicatively coupled to, or otherwise in communication with, Deployment 12 in Region 2.

FIG. 14 is a block diagram 1400 illustrating another example pattern of an IaaS architecture, according to at least one embodiment. Service operators 1402 (e.g. service operators 1202 of FIG. 12) can be communicatively coupled to a secure host tenancy 1404 (e.g. the secure host tenancy 1204 of FIG. 12) that can include a virtual cloud network (VCN) 1406 (e.g. the VCN 1206 of FIG. 12) and a secure host subnet 1408 (e.g. the secure host subnet 1208 of FIG. 12). The VCN 1406 can include an LPG 1410 (e.g. the LPG 1210 of FIG. 12) that can be communicatively coupled to an SSH VCN 1412 (e.g. the SSH VCN 1212 of FIG. 12) via an LPG 1410 contained in the SSH VCN 1412. The SSH VCN 1412 can include an SSH subnet 1414 (e.g. the SSH subnet 1214 of FIG. 12), and the SSH VCN 1412 can be communicatively coupled to a control plane VCN 1416 (e.g. the control plane VCN 1216 of FIG. 12) via an LPG 1410 contained in the control plane VCN 1416 and to a data plane VCN 1418 (e.g. the data plane 1218 of FIG. 12) via an LPG 1410 contained in the data plane VCN 1418. The control plane VCN 1416 and the data plane VCN 1418 can be contained in a service tenancy 1419 (e.g. the service tenancy 1219 of FIG. 12).

The control plane VCN 1416 can include a control plane DMZ tier 1420 (e.g. the control plane DMZ tier 1220 of FIG. 12) that can include load balancer (LB) subnet(s) 1422 (e.g. LB subnet(s) 1222 of FIG. 12), a control plane app tier 1424 (e.g. the control plane app tier 1224 of FIG. 12) that can include app subnet(s) 1426 (e.g. similar to app subnet(s) 1226 of FIG. 12), a control plane data tier 1428 (e.g. the control plane data tier 1228 of FIG. 12) that can include DB subnet(s) 1430. The LB subnet(s) 1422 contained in the control plane DMZ tier 1420 can be communicatively coupled to the app subnet(s) 1426 contained in the control plane app tier 1424 and to an Internet gateway 1434 (e.g. the Internet gateway 1234 of FIG. 12) that can be contained in the control plane VCN 1416, and the app subnet(s) 1426 can be communicatively coupled to the DB subnet(s) 1430 contained in the control plane data tier 1428 and to a service gateway 1436 (e.g. the service gateway of FIG. 12) and a network address translation (NAT) gateway 1438 (e.g. the NAT gateway 1238 of FIG. 12). The control plane VCN 1416 can include the service gateway 1436 and the NAT gateway 1438.

The data plane VCN 1418 can include a data plane app tier 1446 (e.g. the data plane app tier 1246 of FIG. 12), a data plane DMZ tier 1448 (e.g. the data plane DMZ tier 1248 of FIG. 12), and a data plane data tier 1450 (e.g. the data plane data tier 1250 of FIG. 12). The data plane DMZ tier 1448 can include LB subnet(s) 1422 that can be communicatively coupled to trusted app subnet(s) 1460 and untrusted app subnet(s) 1462 of the data plane app tier 1446 and the Internet gateway 1434 contained in the data plane VCN 1418. The trusted app subnet(s) 1460 can be communicatively coupled to the service gateway 1436 contained in the data plane VCN 1418, the NAT gateway 1438 contained in the data plane VCN 1418, and DB subnet(s) 1430 contained in the data plane data tier 1450. The untrusted app subnet(s) 1462 can be communicatively coupled to the service gateway 1436 contained in the data plane VCN 1418 and DB subnet(s) 1430 contained in the data plane data tier 1450. The data plane data tier 1450 can include DB subnet(s) 1430 that can be communicatively coupled to the service gateway 1436 contained in the data plane VCN 1418.

The untrusted app subnet(s) 1462 can include one or more primary VNICs 1464(1)-(N) that can be communicatively coupled to tenant virtual machines (VMs) 1466(1)-(N). Each tenant VM 1466(1)-(N) can be communicatively coupled to a respective app subnet 1467(1)-(N) that can be contained in respective container egress VCNs 1468(1)-(N) that can be contained in respective customer tenancies 1470(1)-(N). Respective secondary VNICs 1472(1)-(N) can facilitate communication between the untrusted app subnet(s) 1462 contained in the data plane VCN 1418 and the app subnet contained in the container egress VCNs 1468(1)-(N). Each container egress VCNs 1468(1)-(N) can include a NAT gateway 1438 that can be communicatively coupled to public Internet 1454 (e.g. public Internet 1254 of FIG. 12).

The Internet gateway 1434 contained in the control plane VCN 1416 and contained in the data plane VCN 1418 can be communicatively coupled to a metadata management service 1452 (e.g. the metadata management system 1252 of FIG. 12) that can be communicatively coupled to public Internet 1454. Public Internet 1454 can be communicatively coupled to the NAT gateway 1438 contained in the control plane VCN 1416 and contained in the data plane VCN 1418. The service gateway 1436 contained in the control plane VCN 1416 and contained in the data plane VCN 1418 can be communicatively couple to cloud services 1456.

In some embodiments, the data plane VCN 1418 can be integrated with customer tenancies 1470. This integration can be useful or desirable for customers of the IaaS provider in some cases such as a case that may desire support when executing code. The customer may provide code to run that may be destructive, may communicate with other customer resources, or may otherwise cause undesirable effects. In response to this, the IaaS provider may determine whether to run code given to the IaaS provider by the customer.

In some examples, the customer of the IaaS provider may grant temporary network access to the IaaS provider and request a function to be attached to the data plane tier app 1446. Code to run the function may be executed in the VMs 1466(1)-(N), and the code may not be configured to run anywhere else on the data plane VCN 1418. Each VM 1466(1)-(N) may be connected to one customer tenancy 1470. Respective containers 1471(1)-(N) contained in the VMs 1466(1)-(N) may be configured to run the code. In this case, there can be a dual isolation (e.g., the containers 1471(1)-(N) running code, where the containers 1471(1)-(N) may be contained in at least the VM 1466(1)-(N) that are contained in the untrusted app subnet(s) 1462), which may help prevent incorrect or otherwise undesirable code from damaging the network of the IaaS provider or from damaging a network of a different customer. The containers 1471(1)-(N) may be communicatively coupled to the customer tenancy 1470 and may be configured to transmit or receive data from the customer tenancy 1470. The containers 1471(1)-(N) may not be configured to transmit or receive data from any other entity in the data plane VCN 1418. Upon completion of running the code, the IaaS provider may kill or otherwise dispose of the containers 1471(1)-(N).

In some embodiments, the trusted app subnet(s) 1460 may run code that may be owned or operated by the IaaS provider. In this embodiment, the trusted app subnet(s) 1460 may be communicatively coupled to the DB subnet(s) 1430 and be configured to execute CRUD operations in the DB subnet(s) 1430. The untrusted app subnet(s) 1462 may be communicatively coupled to the DB subnet(s) 1430, but in this embodiment, the untrusted app subnet(s) may be configured to execute read operations in the DB subnet(s) 1430. The containers 1471(1)-(N) that can be contained in the VM 1466(1)-(N) of each customer and that may run code from the customer may not be communicatively coupled with the DB subnet(s) 1430.

In other embodiments, the control plane VCN 1416 and the data plane VCN 1418 may not be directly communicatively coupled. In this embodiment, there may be no direct communication between the control plane VCN 1416 and the data plane VCN 1418. However, communication can occur indirectly through at least one method. An LPG 1410 may be established by the IaaS provider that can facilitate communication between the control plane VCN 1416 and the data plane VCN 1418. In another example, the control plane VCN 1416 or the data plane VCN 1418 can make a call to cloud services 1456 via the service gateway 1436.

The secondary VNICs 1572(1)-(N) can transmit the calls to the NAT gateway 1538 that may transmit the calls to public Internet 1554. In this example, the containers 1567(1)-(N) that can be accessed in real-time by the customer can be isolated from the control plane VCN 1516 and can be isolated from other entities contained in the data plane VCN 1518. The containers 1567(1)-(N) may also be isolated from resources from other customers.

In other examples, the customer can use the containers 1567(1)-(N) to call cloud services 1556. In this example, the customer may run code in the containers 1567(1)-(N) that requests a service from cloud services 1556. The containers 1567(1)-(N) can transmit this request to the secondary VNICs 1572(1)-(N) that can transmit the request to the NAT gateway that can transmit the request to public Internet 1554. Public Internet 1554 can transmit the request to LB subnet(s) 1522 contained in the control plane VCN 1516 via the Internet gateway 1534. In response to determining the request is valid, the LB subnet(s) can transmit the request to app subnet(s) 1526 that can transmit the request to cloud services 1556 via the service gateway 1536.
