The present disclosure relates generally to threat detection, and more particularly, to techniques (e.g., systems, methods, computer program products storing code or instructions executable by one or more processors) for analyzing security events using dynamic policies and displaying a consolidated view of active threats and user activity including the dynamic policies being triggered by the active threats and user activity.
Computer networks have become important tools for modern business. Today a large amount of information is stored in and accessed across such networks by users throughout the world. Much of this information is, to some degree, private or confidential and protection of the information is required. Not surprisingly then, various network security monitor devices have been developed to help uncover attempts by unauthorized persons and/or devices to gain access to computer networks and the information stored therein.
Network security products largely include Intrusion Detection Systems (IDSs), which can be Network or Host based (NIDS and HIDS respectively). Other network security products include firewalls, router logs, and various other event reporting devices. Due to the size of their networks, many enterprises deploy hundreds or thousands of these products through-out their networks. Thus, network security personnel are bombarded with alarms representing possible security threats. Most enterprises do not have the resources or the qualified personnel to individually attend to all of the received alarms.
Therefore, techniques for analyzing security events and providing a threat visualization that presents real-time data analytics in a manner that is easily understandable to an end user is desired.
As static security rules cannot match evolving threats from comprised users, applications, and hosts, where there is an extremely high volume of user activity (with billions of events per day), a threat intelligence platform may be provided. Some embodiments can provide the ability to provide real-time threat detection and analytics. Certain embodiments can provide visibility into users, application usage and performance. Some embodiments can provide real-time enforcement leveraging existing access controls. Certain embodiments can enforce compliance and block users to unsanctioned applications, perform adaptive authorization and challenges to users based on policy, and perform content inspection for privacy and leakage. Certain embodiments may perform real-time enforcement using rules and analytics. Some embodiments may collect, monitor, and visualize and act on very large volumes of security data in real-time (i.e., billions of events per day)

I. Introduction
The following disclosure describes a threat intelligence platform that can provide real-time threat detection and analytics. In various embodiments, a system may be provided for that includes: a processor; and a memory storing a set of instructions which when executed by the processor configure the processor to: receive a security event from an agent, the security event including at least a destination and a source; trigger a policy when the security event corresponds to a policy, wherein the policy includes a specification of the source, the destination, and an enforcement action; implement the enforcement action for the security event based on the policy; and update a user interface to link the source and destination of the security event through the triggered policy. However, an entity (e.g., a company, a country) may have thousands or hundreds of thousands of employees and other individuals (e.g., users, consultants, guests) who are constantly accessing various services (e.g., sources) through its network generating security events. As people are attempting to gain access to a wide variety services, there may be various access violations, password errors and such that would necessitate monitoring. Currently, static security rules within security policies are not able to match evolving threats for compromised users, compromised applications, and compromised hosts. Manual or home-grown analysis with user interfaces is cost prohibitive as there is an extremely high volume of user activity (e.g., billions of events per day). Moreover, it is difficult to have automated pattern detection for a large number of users that would be highly accurate and thereby be capable of preventing those unauthorized users from gaining access to services.
To address these problems, various embodiments provide techniques (e.g., systems, methods, computer program products storing code or instructions executable by one or more processors) for analyzing security events using dynamic policies and displaying a consolidated view of active threats and user activity including the dynamic policies being triggered by the active threats and user activity. Some embodiments may track user access and collect information in real-time to identify patterns, produce analytics, and take corrective actions accordingly. By collecting data in real-time or near real-time, corrective actions determined based on the data can be immediately applied. For example, when a user is authenticating against an application, there would only be a short period of time (e.g., milliseconds) until when action(s) would need to be taken to prevent an unauthorized user from gaining access to content. In additional or alternative embodiments, by collecting data in real-time or near real-time and keeping a history of such data, corrective actions determined based on the real-time data and historical data can be applied to prevent the unauthorized user from gaining access even after the user has been authenticated, and take the user out of the network.
Some embodiments provide visibility into the identity of users, resource usage patterns, and performance characteristics. In certain embodiments, the techniques can provide real-time enforcement leveraging certain access controls. For example, certain embodiments may enforce compliance or block users to unsanctioned applications, perform adaptive authorization, challenge users based on policy, and perform content inspection for privacy and leakage. Certain embodiments may provide real-time enforcement using dynamic rules and analytics. Some embodiments may provide a threat visualization that presents real-time data analytics in a manner that is easily understandable to an end user. By digesting a large amount of data and presenting the analyzed data in real-time and in a meaningful way, an end user may identify actionable items and ensure that certain policies are enforced while also ensuring that appropriate policies are updated.
In one example, as a user is in a login page and typing in the username and password and submitting those user credentials, the user credentials are being sent in real-time or near real time to a data collection bus. In some instances, the data can be collected and sent less than every second or 30 milliseconds, depending on a set of tuning parameters (e.g., whether the collection bus is sitting in the cloud, etc.). Aside from the network latency (e.g., when the agent is on a host machine collecting information and the data collector bus is on a different machine such as in the cloud), there is very little delay in the transporting of data (i.e., near real-time). Nonetheless, as the user types in the credentials, the system may determine whether these credentials typically come from a particular server and determines that additional challenges may need to be presented to the user if there is suspicious activity. By the time the user accesses the page, if the system determines that the user should not be authorized despite the credentials being validated, the system will kick the user out of accessing the page.
In some embodiments, a Web proxy can constantly monitor and learn user activity and behavior and trigger an anomaly (thereby cause additional challenges to be presented to the user), after the user logs into an account. For example, the user may try to transfer a large sum of money. This action may trigger the system to present the user with additional challenges. In certain embodiments, the proxy may provide another source of information (e.g., traffic flow) and the collected data is fed and analyzed in real time. When a user is accessing a protected application or a cloud application that is not protected by an agent, the proxy server can determine the user's activity e.g., that the user is going to a certain website to download information. The proxy server can monitor the user activity and provide information that the user is blacklisted because of the collected data. Further, the proxy may provide historical information such that when the user is accessing a new site, the historical information pertaining to the user can be taken into consideration when granting access to the user.
Some embodiments can feed the real time data as it becomes available to a real time visualization server and present the analytics to a customer in real time. As the data is provided to the customer in real time, an action may be determined quickly and responsive to those real time analytics. Some embodiments may store the data and use the stored or historical data to come up with additional rules and policies that can be applied in real time. By mining historical data, certain embodiments may produce enforcement policies based on the historical data. Certain embodiments may use both historical data and analytics that is computed in real time and trigger an anomaly accordingly. Advantageously, these approaches are capable of collecting, monitoring, visualizing, and taking action on very large volumes of security data in real-time (i.e., billions of streaming events).
II. System Architecture for Threat Detection
Network 120 may facilitate communications and exchange of data between user device 115, access management and threat detection system 105, and information management system 110. Network 120 may be any type of network familiar to those skilled in the art that can support data communications using any of a variety of commercially-available protocols, including without limitation TCP/IP, SNA, IPX, AppleTalk, and the like. Merely by way of example, network 115 can be a local area network (LAN) such as an Ethernet network, a Token-Ring network and/or the like, a wide-area network, a virtual network, including without limitation a virtual private network (VPN), the Internet, an intranet, an extranet, a public switched telephone network (PSTN), an infra-red network, a wireless network (e.g., a network operating under any of the IEEE 802.1X suite of protocols, the Bluetooth protocol known in the art, and/or any other wireless protocol), and/or any combination of these and/or other networks.
User device 110 may be general purpose personal computers (including, by way of example, personal computers and/or laptop computers running various versions of Microsoft Windows and/or Apple Macintosh operating systems), cell phones or PDAs (running software such as Microsoft Windows Mobile and being Internet, e-mail, SMS, Blackberry, or other communication protocol enabled), 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), or any other computing device. For example, user device 110 may be any other electronic device, such as a thin-client computer, Internet-enabled gaming system, and/or personal messaging device, capable of communicating over a network (e.g., network 115). Although exemplary system environment 100 is shown with one user device, any number of user and/or client computing devices may be supported, in other embodiments.
Access management and threat detection system 105 may comprise one or more computers and/or servers, which may be general purpose computers, specialized server computers (including, by way of example, PC servers, UNIX servers, mid-range servers, mainframe computers, rack-mounted servers, etc.), server farms, server clusters, or any other appropriate arrangement and/or combination. The computing devices that make up access management and threat detection system 105 may run any of operating systems or a variety of additional server applications and/or mid-tier applications, including HTTP servers, FTP servers, CGI servers, Java servers, database servers, and the like. Exemplary database servers include without limitation those commercially available from Oracle, Microsoft, Sybase, IBM and the like.
In various embodiments, the access management and threat detection system 105 may comprise one or more components operable to protect resources 125 provided by one or more target systems 130 of an organization. In some embodiments, a ‘target system’ may refer to any system that provides or comprises one or more resources. Resources 125 to which access is provided, either locally or remotely, by a target system 130 may be of various types including software products, applications (e.g., cloud-based applications, enterprise applications, or any other applications), cloud services, various types of data (e.g., networked files, directory information, databases, or the like), and other resources. A target system 130 may include one or more databases, lightweight directory access protocol (LDAP) servers, Active Directory (AD) systems, Email Systems, UNIX systems and the like. For example, a target system 130 may be an Active Directory (AD) system that provides access to active directory services to access an Active Directory server. In some examples, a target system 130 may be a computing system that provides access to a meeting room, such as access to the meeting room using a badge. In some embodiments, a target system 130 may also be referred to as an application instance.
In certain embodiments, access to resources 125 provided by a target system 130 may be controlled using various types of accounts in the target system 130. An account may be provisioned in a target system 130 based upon the resources 125 provided by the target system 130. An account may be of various types such as user accounts, administrative accounts, application accounts, and the like, with each account type providing a particular level of access to one or more resources 125 provided by the target system 130. Separate accounts (e.g., user accounts, administrative accounts, and/or application accounts) may be provided in a target system 130 to enable a user to access or otherwise log into the target system 130. An account may be created, or provisioned, to a user or a group of users (e.g., an organization) based on the identity of the user or the group of users. A user or a group of users may be provided with a particular account type to access a particular resource type. For instance, an e-mail account on an Exchange server provided to a user may be an account of a resource type Exchange. A user may be given multiple accounts, each corresponding to an account type for a resource type. For example, a user may have two different accounts for logging into a target system 130 to perform different types of operations. For example, a target system 130 may host an Email exchange server and provide an email account type. The same target system 130 may also host an human resource (HR) system and provide an HR administrator account type for performing administrative functions related to the HR system. A particular user may have an email account on the target system 130 and also have an HR administrative account on the target system 130. When logged in using the email account, the user may access emails. When logged in using the HR administrative account, the user can perform administrative tasks related to managing resources in an organization.
In accordance with at least some embodiments, a user on a user device 115 may communicate with a target system 130 to request for a resource 125 (e.g., an email application) by accessing a web-based request user interface (UI) on user device 115. For example, request UI may include a graphical user interface viewable via a client application (e.g., a browser) on the user's device 115. When a user wishes to access a resource on a target system 130 or attempt to perform an operation on a resource on target system 130, access management and threat detection system 105 may intercept the access request from the user, and attempt to first authenticate/authorize the user. For example, the access management and threat detection system 105 may provide the user with a log-in page to obtain the user's credentials (e.g., log-in identifier and password). The access management and threat detection system 105 may then be configured to determine if the user is an authorized user based on the user's login credentials. The access management and threat detection system 105 may be configured to receive various types of access requests such as web requests, SDK requests, programmatic requests, and the like for various events/operations (e.g., authN, authZ, policy checks, stepup authN, sso, token issuance) via various channels (HTTP, OAP) from the users.
In various embodiments, the access management and threat detection system 105 includes one or more agents 135, one or more proxies 140 (e.g., forward or reverse proxies), one or more access managers 145, and/or one or more Webgates 150. The access management and threat detection system 105 may be implemented in system 100 according to an agent-server model for enabling communication between user device 115 and target system 130 (e.g., a distributed environment server) to provide access control functionality over resource 125. The agent-server model may include an agent component (e.g., the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 also known as a single sign-on agent or policy-enforcement agent) and a server component (e.g., one or more access managers 145 also known as a single sign-on server or policy server). For example, the one or more access managers 145 may serve as the decision component for controlling access to the resource 125, and the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 may implement or operate as the enforcement component for controlling access to the resource 125. In some embodiments, the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 may be deployed with the resource 125 as a plugin or as a portion of the resource 125, or the one or more agents 135, one or more proxies 140, or one or more Webgates 150 may be provisioned separate from the resource 125, for example, running on a web server in front of the resource 125. The one or more access managers 145 may be deployed as a part of the identity access manager.
The access management and threat detection system 105 enables SSO functionality within a distributed environment, and may perform various access control related functions for managing access to resources within the distributed environment. For example, the one or more agents 135, one or more proxies 140, one or more access managers 145, and/or one or more Webgates 150 may perform authentication of a user operating a user device 115. Authentication is a process by which a user is verified to determine that he/she is who he/she claims to be. To authenticate a user, access management and threat detection system 105 may present a user with a request for authentication credentials in the form of a challenge (e.g., via the user's web browser). Enforcement policies (e.g., authentication policies) may specify the authentication methodology to be used for authenticating the user for whom the access must be provided on a given resource. The policies define the way in which the resource access is to be protected (e.g., type of encryption, or the like). The one or more access managers 145 may determine authorization of a user to access a resource 125. Authorization is the process of determining if a user has a right to access a requested resource. Enforcement policies (e.g., authorization policies) may be defined that specify the conditions under which a user or group of users has access to a resource. For example, an administrator may only authorize certain users within a group to access particular resources.
The one or more agents 135 may be policy enforcement agents that act as a filter for resource requests. The one or more agents 135 may intercept resource requests and apply static and dynamic enforcement policies to determine whether the requested resources are protected by the access management and threat detection system 105. If so, the resource request may be forwarded to one or more access managers 145 to determine whether the user requesting the protected resource may access the protected resource. In certain embodiments, one or more Webgates 150, an out of the box solution developed by Oracle International Corporation, may be used as an agent so that it can filter the resource requests. It should be noted that the one or more agents 135 and one or more Webgates 150 may be a hardware structure or a combination of hardware and software implementations, in accordance with some embodiments.
The one or more proxies 140 may be policy enforcement agents that act as a filter for resource requests. For example, the one or more proxies 140 may be authentication proxies that handle user authentication for resources. The authentication proxies may be called (e.g., instantiated) by a web application or the resources to provide authentication capabilities. In some embodiments, the authentication proxies may include a high-level API that integrates one or more low-level authentication schemes to allow for programs that rely on authentication to be designed and written independently of an underlying authentication scheme. The one or more proxies 140 may intercept resource requests and apply astatic and dynamic enforcement policies to determine whether the requested resources are protected by the access management and threat detection system 105. If so, the resource request may be forwarded to one or more access managers 145 to determine whether the client requesting the protected resource may access the protected resource. An example of such an authentication proxy is a pluggable authentication module (PAM) used in Linux systems. It should be noted that the one or more proxies 140 may be a hardware structure or a combination of hardware and software implementations, in accordance with some embodiments.
The one or more access managers 145 may have multiple components for authentication and/or authorization processes. Additionally, the one or more access managers 145 may include one or more authentication schemes. The authentication schemes may be configured to protect the resources using one or more access policies (e.g., static and dynamic enforcement policies as discussed herein). The authentication schemes may include details about a credential collection mechanism and type of credential collector used to collect credentials. For example, credential collection may occur using an HTTP(S) transport channel that is handling HTTP(S) request from a remote user. In certain embodiments, the authentication schemes may identify a redirect URL (Uniform Resource Locator), which is used to notify the user device 115 of the success or failure of the authentication and/or authorization processes. In addition, the authentication scheme may identify an authentication level indicating the trust level to protect transport of credentials from the user device 115. For example, an LDAP (Lightweight Directory Access Protocol) scheme may be at authentication level 2 with an LDAP authentication module to protect Manager-related resource, e.g., URLs, based on a form challenge method. In the form challenge method, an HTML form with one or more text input fields may be used to gather credential information. In some embodiments, the form-based challenge may collect credentials such as username and password, social security number, date of birth, one time password, or a combination of other common parameters.
Based on receiving the proper authentication credentials for the user, the one or more access managers 145 may forward the user back to the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150, the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 may check the authentication, and establish a first session for the user upon authentication of the user. As a result, the user is logged into the target system 130 (e.g., a distributed environment server) for the session. Once logged in, the user may access resources to which the user is authorized to access, such as running different applications, accessing cloud storage, or the like. Once the user is logged into the target system 130, the one or more access managers 145 may create a cookie that tracks session activity for user. The cookie may include a length of time that the user has been active on a session. The cookie may be stored as session activity data within the information management system 110.
Upon determining that user is authenticated for a SSO session, the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 may process the original request for resource 125 by directing an authorization query to the one or more access managers 145. The one or more access managers 145 checks relevant enforcement policies for the resource 125 to determine whether the user is authorized to access to the resource 125. The one or more access managers 145 responds to the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 with an allow or deny message based on the enforcement policies. Upon determining that the user is allowed access to the resource 125, the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 allow the request from the user device 115 for access to the resource 125 to go through and the user can access the resource 125 on the target system 130 via user device 115. Upon determining that the user is denied access to the resource 125, the one or more agents 135, one or more proxies 140, and/or one or more Webgates 150 notifies the user device 115 that access to the resource 125 for the user is not permitted.
Information management system 110 may comprise one or more computers and/or servers, which may be general purpose computers, specialized server computers (including, by way of example, PC servers, UNIX servers, mid-range servers, mainframe computers, rack-mounted servers, etc.), server farms, server clusters, or any other appropriate arrangement and/or combination. The computing devices that make up information management system 110 may run any of operating systems or a variety of additional server applications and/or mid-tier applications, including HTTP servers, FTP servers, CGI servers, Java servers, database servers, and the like. Exemplary database servers include without limitation those commercially available from Oracle, Microsoft, Sybase, IBM and the like.
In various embodiments, the information management system 110 is responsible for supporting the access management and threat detection system 105 to protect and authorize user access to resources 125. The information management system 110 may be configured to obtain additional information associated with a user's access request in order to authenticate/authorize the user's access into the target system 130. This information may include, for instance, the client IP address from where the request originated, device information, user information, resource being requested, time of request, and so on. The information management system 110 may be further configured to analyze the information to create and publish new policies (e.g., dynamic inspection and enforcement policies) that overwrite static policies for a predetermined period of time. In some embodiments, as the real-time data becomes available it is presented visually as a part of system threat analytics to a customer. As the data is provided to the customer in real-time, an action may be determined quickly and responsive to those real-time threat analytics. Various embodiments may store the data and use the stored data (i.e., historical data) to generate additional rules or policies that can be applied in real-time. By mining historical data, certain embodiments may produce dynamic inspection and enforcement policies based on the historical data. In other embodiments, both the historical data and analytics from the analyzed information that is computed in real-time are used to produce dynamic inspection and enforcement policies.
The collection bus 205 and policy bus 210 include a network topology in which nodes such as the analytics server 220, the machine learning component 225, the visualization server 230, the one or more agents 235, the one or more proxies 240, the one or more access managers 245, and/or the one or more Webgates 250 are connected to a common linear (or branched) link called a bus or enterprise service bus. The collection bus 205 and policy bus 210 implement a software architecture for distributed computing that include routing messages and data between the various nodes, controlling deployment of various policies (inspection and enforcement policies), and providing services such as facilitating the collection of data based on inspection policies and publishing the various policies (inspection and enforcement policies) to listeners (i.e., the agents).
The an analytics server 220, machine learning component 225, and visualization server 230 may comprise one or more computers and/or servers, which may be general purpose computers, specialized server computers (including, by way of example, PC servers, UNIX servers, mid-range servers, mainframe computers, rack-mounted servers, etc.), server farms, server clusters, or any other appropriate arrangement and/or combination. The computing devices that make up analytics server 220, machine learning component 225, and visualization server 230 may run any of operating systems or a variety of additional server applications and/or mid-tier applications, including HTTP servers, FTP servers, CGI servers, Java servers, database servers, and the like. Exemplary database servers include without limitation those commercially available from Oracle, Microsoft, Sybase, IBM and the like.
The system memory 255 may be one or more storage mediums, including for example, non-transitory machine readable storage medium such as flash memory, permanent memory such as read-only memory (“ROM”), semi-permanent memory such as random access memory (“RAM”), any other suitable type of non-transitory storage component, or any combination thereof. The memory 255 provides for storage of computer readable program instructions, data structures, program modules and other data for operation of the system 200 in accordance with the different aspects. In embodiments, memory 255 may store an operating system, application programs, the policies, data such as information related to a user's activity and access requests, and program data in accordance with certain aspects.
With the system of
In certain embodiments, the general method proceeds as follows. An end user enters a URL or an identification of a requested resource residing in a protected policy domain. The user's browser sends the URL as part of an HTTP request to a Web Server. The one or more agents 235, one or more proxies 240, and/or one or more Webgates 250 recognize and intercept the request. If the end user has not already been authenticated, the one or more agents 235, one or more proxies 240, and/or one or more Webgates 250 causes the Web Server to issue a challenge to the browser for log-in information. The received log-in information is then passed back to the Web Server and on to the one or more agents 235, one or more proxies 240, and/or one or more Webgates 250. The one or more agents 235, one or more proxies 240, and/or one or more Webgates 250 in turn makes an authentication request to the one or more access managers 245, which determines whether the user's supplied log-in information is authentic or not. The one or more access managers 245 performs the authentication by accessing attributes of the user's identity profile and the resource's authentication criteria stored in memory 255. If the user's supplied log-in information satisfies the authentication criteria, the process flows as described below; otherwise, the end user is notified that access to the requested resource is denied and the process halts.
After authenticating the user, the one or more agents 235, one or more proxies 240, and/or one or more Webgates 250 queries the one or more access managers 245 about whether the user is authorized to access the resource requested. The one or more access managers 245 in turn queries information management system 200 for the appropriate authorization criteria for the requested resource. The one or more access managers 245 retrieves the authorization criteria for the resource and answers the one or more agents 235, one or more proxies 240, and/or one or more Webgates 250 authorization query, based on the resource's authorization criteria and the user's identity profile. If the user is authorized, the user is granted access to the resource; otherwise, the user's request is denied. Various alternatives to the above described flow are also within the spirit and scope of the present invention.
The authentication and authorization decisions may be made based on policy domains and policies (e.g., static and dynamic enforcement policies). A policy domain is a logical grouping including Web Server host ID's, host names, URL prefixes, and rules. Host names and URL prefixes specify the course-grain portion of the web name space a given policy domain protects. Rules of the policy domain specify the conditions in which access to requested resources is allowed or denied, and to which end users these conditions apply. Policy domains may comprise two levels of rules: first level default rules and second level rules contained in policies. The first level default rules may apply to any resource in a policy domain not associated with a policy. The second level rules may apply to any resource in a policy domain associated with a policy. A policy is a grouping including a URL pattern, resource type, operation type (such as a request method), and rules that restrict access to particular resources by user, static or dynamic group memberships, time of the day or week, IP (Internet Protocol) addresses, etc. A policy may be static or dynamic, attached to a policy domain, and specify the fine-grain portion of a web name space that a policy protects. In practice, the host names and URL prefixes from the policy's policy domain are logically concatenated with the policy's URL pattern. The resulting overall pattern is compared to the incoming URL. If there is a match, then the policy's various rules are evaluated to determine whether the request should be allowed or denied; if there is not a match, then default policy domain rules are used.
The static and dynamic enforcement policies are statements that bring together attributes to express what is allowed and what is not allowed. The enforcement policies may use any type of attributes (user attributes, resource attributes, object, actions, environment attributes, etc.) and comprise logic such as Boolean logic, in which rules contain statements (e.g., “IF, THEN”) to evaluate the attributes and determine what is allowed and is not allowed (e.g., whether the user making the request is authenticated, whether the user making the request is authorized to access the requested resource, whether the user making the request is authorized to take the request action on the requested resource, etc). For example: IF the requestor is a manager, THEN allow read/write access to sensitive data. The static enforcement policies comprise default rules or rules written/rewritten through-out the life span of the system (e.g., created by an administrator of the system) to evaluate evolving dynamics or attributes of the system. However, the rules contained within the static policies are not written/rewritten in real-time such that the policy is capable of evaluating evolving dynamics or attributes of the system in real-time. On the other hand, the dynamic enforcement policies comprise rules written/rewritten (e.g., created by machine learning techniques or an administrator of the system) to evaluate evolving dynamics or attributes of the system in real-time.
In various embodiments, systems and methods for static and dynamic policy provisioning and enforcement are provided based on threat detection. The static and dynamic enforcement policies may be enforced by the various agents (e.g., one or more agents 235, one or more proxies 240, and/or one or more Webgates 250) along the enforcement path and the policies may be interpreted as each applies to the agents' position in the enforcement path. In some embodiments, the dynamic policies can be created manually by an administrator or can be injected automatically by the machine learning component 225 into the system. Certain embodiments may also designate a time period (e.g., a predetermined period of time) in which the dynamic policy should be run. For example, a policy may be set for only a predetermined period of time (e.g., 5 minutes, 10 minutes, 4 hours, 1 day, 2 weeks, etc.) to allow the analytics server 220 and/or administrator to monitor and trigger anomalies based on data in that predetermined period of time. The policy may then expire after the predetermined period of time. As such, some embodiments may monitor the behavior and ensure the stability of the system with the newly added dynamic policy. The dynamic policies can be modified as they are monitored and can become a solid or persistent policy (i.e., not bounded by the predetermined period of time). Using the machine learning capabilities, some embodiments may create a dynamic policy for a predetermined time period (e.g., the next 30 minutes) and eventually have it permanently overwrite the static policies that are configured for the system. As should be understood, it would be inefficient and resource consuming to have a security administrator, who is viewing a visualization application, generate these policies quickly and push them into the system regardless of whether a full approval process is needed.
In some embodiments, a sticky policy (i.e., a static policy that cannot be overwritten) may be created where the policy may not be affected by the machine learning component 225. In other embodiments, the machine learning component 225 can learn about the default policies or policies created by an administrator (e.g., static policies that can be overwritten) and modify the policies or overwrite the policies with dynamic policies. In certain embodiments, the machine learning may cause a default policy or static policy previously configured by a system administrator to change based on additional data, and overwrite the default policy or static policy. For example, an anomaly can be put into a certain category that corresponds to a block policy, which is a high alert policy, that may overwrite another category such as a second factor authentication where even if a user is in a valid session, some action performed by the user may cause a form or a question to be present to the user for an additional layer of authentication. Other embodiments may specify to never create a block policy (e.g., a policy with logic configured to block a user or group of users from an action such as read/write on a resource), so that the administrator can monitor the types of policies the machine learning is triggering. For example, the administrator may for the first few months observe that the machine learning is creating several high alerts under certain circumstances or when there are certain patterns, verify those alerts, and determine that that the machine learning is not creating a high number of false positives. Then, the administrator may adjust the policy and indicate that instead of creating a high alert for this pattern, create a second factor authentication policy for the same pattern.
In one example, a user can be accessing servers (e.g., a target system) every day from 7-9 am from home or another location, and then from 10 am to 4 pm, accessing the servers from work or the headquarters. When the user travels to another location and tries to access the servers, the analytics server 220 may determine that the accessing is an anomaly and thereby trigger a second factor authentication because the system had already configured with a default or static policy for the anomaly to trigger second factor authentication when the location based data does not match the historical data. After a period of time, the system may learn and adapt from the default or static policies and determine that based on user behavior pattern, the system should not trigger an anomaly when the user is traveling to the other location. The system may also differentiate a user behavior pattern. Based on historical data and updated real-time data, the system may determine whether an anomaly should be triggered intelligently. The machine learning component 225 can be constantly learning from historical data and real-time data to create and modify the end user identity profiles or models of behavior and the polices governing the behavior. Instead of updating the identity profiles and policies every week or every other week, these identity profiles and policies are updated in real-time such that the following anomaly detections have taken all historical data and real-time data of the user's activity into account. This enables something that might have been identified as an anomaly to be taken into account promptly for the next determination. So in this example, the new location has already been updated in the memory 255 such that the next time the user logs in while the user is in this geographic location, the activity on the system doesn't cause the anomaly detection to be triggered. In essence, a new dynamic policy has been created that overwrites the previous policy.
In certain embodiments, anything that is published in the enterprise (e.g., on a network of the enterprise) may be available in the real-time data collection via the collection bus 205 and consumed and analyzed by the analytics server 220. In some embodiments, the analytics server 220 can perform event correlation and generate reports and publish the reports on a report bus 275. The report bus 275 is the bus from which the machine learning component 225 continuously receives the information in real time and then provides the information via visualization server 230 through a user interface. The machine learning component 225 is also consuming the real-time events as well as historical data from the collection bus 205, the memory 255, and the report bus 275. Accordingly, the machine learning component 225 can find anomalies and publish a policy (inspection or enforcement) into the policy bus 210.
In conventional techniques, agents may be configured to collect data, log the data as log ascii data name value pairs, and send the log periodically (e.g., every 5 minutes or 10 minutes) to a server. As the agents may be in the cloud, while the server is in the enterprise or the other way around, the shipping of these logs may be expensive. Moreover, by accumulating the logs and sending them altogether, it is time consuming. Instead of collecting and sending log ascii data name value pairs, various embodiments operate in real-time by using binary data to transport the data from the various agents to the collection bus 205 so the data is highly compressed. Certain embodiments may send the values and the mechanisms to map the data. For example, values may be sent from an agent to the collection bus 205, and the collection bus 205 will determine what kind of format is being sent from the agent (e.g., Schema 1). Once the format is identified, the values can be interpreted. This is a compressed and efficient way of transporting data.
In various embodiments, to detect and trigger a threat, the system may rely on data captured and sent by the agent(s) including one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250. A predefined set of attributes (e.g., user attributes, resource attributes, object, actions, environment attributes, etc.) may not suffice when the agent(s) have to support newer target systems, application(s), and change in existing application interfaces. Accordingly, the use of dynamic inspection policies may allow the system to send dynamic rules requesting agents to collect/inspect additional information or attributes such as data in various payloads (e.g., HTTP). This information may then be reported as part of the regular access request event. The machine learning component 225 can then detect anomalies on this new set of data or information, and insert a dynamic enforcement policy, which may then trigger more anomalies. As more anomalies are triggered, additional enforcement policies may be created to prevent particular types of traffic, thus completing the collection, detection, and enforcement cycle.
The collection bus 205 may be configured to obtain the information associated with a security event such as an end user's access request and report the information or data on the report bus 275. The configuration of the collection bus 205 may be based on default or static inspection policies comprising rules for collecting a predefined set of attributes (e.g., user attributes, resource attributes, object, actions, environment attributes, etc.) when certain criteria is satisfied. In certain embodiments, an inspection policy monitors data and informs an administrator when a certain criteria match a predefined pattern. The inspection policy does not cause an alert to be triggered when the pattern exists but collects the predefined set of attributes when the pattern exists. For example, the system may provide an inspection policy user interface (UI) that allows an administrator to designate the triggering of certain inspection policies when a set of criteria has been met (e.g., if header data matches, for a threshold time interval). In accordance with other aspects, the configuration of the collection may be based on dynamic inspection policies comprising rules for collecting the data or attributes. For example, the collection bus 205 and the analytics server 220 may work together to collect the predefined set of attributes and trigger anomalies based on rules that were previously configured (default, static, or dynamic inspection and enforcement policies). The inspection policies can designate the predefined set of attributes to be collected and the criteria for the patterns in the data to be identified. Once the attributes and patterns are collected via the collection bus 205, the analytics server 220 may inspect the attributes and patterns in the data and determine whether the attributes and patterns match any rules defined within the enforcement policies. Once the data comes into the collection bus 205, it may be stored in memory 255 and becomes part of historical data. The machine learning component 225 can be constantly learning from the historical data and real-time data to create and modify the inspection and enforcement policies to efficiently collect information required for threat assessment of user activity on the system.
The information associated with an event may be collected from one or more agents including the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 (as discussed with respect to
In some embodiments, the subset of parameters to be monitored may be identified/defined by a resource (e.g., a target application) on the target system that the user generally accesses and the target application may provide this information to the analytics server 220. For instance, the target application (e.g., a financial application) might want to track a user's access requests based on parameters such as the user id, the time of access, the duration of access, and so on. These parameters are configured with the analytics server 220, and the machine learning component 225 may then create an enforcement policy for a user or group of users by analyzing the incoming real-time data and the historical data of access requests over a period of time, against these parameters. In certain embodiments, in instances where data is not being collected to satisfy the subset of parameters to be monitored, the analytics server 220 and the machine learning component 225 mare configured to create a dynamic inspection policy that is triggered to obtain such data to satisfy the subset of parameters upon certain criteria being satisfied (e.g., the user or group of users logging into the system).
In certain embodiments, the analytics server 220 and machine learning component 225 may be configured to generate multiple policies for the user or group of users. These policies may be generated by analyzing incoming real-time data and the historical data of access requests for a user or group of users against different sets of parameters associated with the access requests. For example, as noted above, the analytics server 220 and machine learning component 225 may be configured to generate a time based policy for a user or group of users by analyzing the user's or group of users' access requests based on the time at which the user or group of users normally accesses various applications stored on the target system. In another instance, the analytics server 220 and machine learning component 225 may be configured to generate an application access pattern policy for the user by analyzing a pattern in which a user accesses various applications stored on the target system. The analytics server 220 and machine learning component 225 may be configured to generate a policy for the user by capturing the characteristics of security threats, intrusion, Denial Of Service (DOS) attacks from the access requests.
In some embodiments, the analytics server 220 and machine learning component 225 may be configured to generate a policy by classifying the incoming real-time data and the historical data of access requests associated with a user or group of users into one or more data clusters. In certain embodiments, the analytics server 220 and machine learning component 225 may be configured to generate the one or more data clusters using supervised or unsupervised machine learning or other clustering (e.g., K-means) techniques. In various embodiments, the machine learning component 225 may be configured to use unsupervised learning using a density based clustering algorithm and Euclidian distance to calculate the distance of the access request from the centroid of the cluster. In certain examples, the radius of the cluster is calculated based on the mean of the distance from centroid of each point in the cluster. Any point falling outside the radius will have higher risk based on the standard deviation. The closer user activity on the enterprise network is to the centroid, the lower is the risk for that access.
The incoming real-time data and the historical data values for parameters configured by the analytics server 220, the machine learning component 225, and/or the integrating application (e.g., the application that the user is requesting access to) can, in certain examples, become data points for building the cluster. Once the cluster is established, the analytics server 220 and machine learning component 225 may be configured to generate a policy that includes rules regarding the one or more data clusters. For example, a rule may be established that states: if certain parameters (x, y, and z) of a request from a user or group of users does not match parameters (x, y, and z) of the cluster then an action may be taken, e.g., a second factor authentication may be requested or a block may be placed on the user or group of users. Consequently, when a new request is received from the user or the group of users, the values of the parameters from the request are matched against the rules in the policy including the already established parameters of the cluster to determine if the access request from the user or group of users is anomalous.
In some embodiments, once the cluster is established, the analytics server 220 and machine learning component 225 may be further configured to categorize the policy based on threat levels. The threat levels may be determined based on the distance calculated from the center of a cluster. As an example, a traffic pattern on the enterprise network can have attributes that are used to generate a policy with rules set on criteria such as a distance of the traffic pattern from one or more clusters. If the distance is one time (e.g., one standard deviation from the mean), then the policy may be classified as a low risk and associated traffic patterns may trigger a low alert. If the distance is two times (e.g., two standard deviation from the mean), then the policy may be classified as a medium risk and associated traffic patterns may trigger a medium alert. If the distance is greater than three times (e.g., greater than three standard deviation from the mean), then the policy may be classified as a block and associated traffic patterns may trigger a block on such activity. Accordingly, the customer need not worry about whether it is an unusual pattern in the traffic pattern. Instead, the customer can be more focused on whether the traffic pattern created a low alert, a medium alert, a high alert, second factor authentication, or a block.
As described herein, a policy can be generated by the analytics server 220 and machine learning component 225, or an administrator (by a person seeing that an anomaly has arisen). Some embodiments use Structured Threat Information eXpression (STIX) as the standard in how the policy is declared. In various embodiments, once a policy (e.g., a new dynamic enforcement policy) is established or generated, the policy is published to the policy bus 210 for consumption by the agents (e.g., the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250) in order to enforce the policy. When the policy is being consumed by the agents, the agents all become a part of an enforcement ecosystem. For example, when a new access request is received from a user or group of users, the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 are configured to analyze the information associated with the access request against an enforcement policy (default, static, or dynamic) to determine if the user's or group of users' access request is anomalous.
In some embodiments, the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 may be configured to first select a policy for the user or group of users from a plurality of enforcement policies that are published on the policy bus 210. In certain embodiments, the policy may be specifically associated with the user or group of users. The selection may be based on, for example, the type of application that the user or group of users is requesting access to. For instance, if the user or group of users is requesting access to a financial application on the target system, the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 may be configured to select a policy from the plurality of policies that analyzes a subset of parameters defined by the financial application. For example, and as noted above, a financial application might want to analyze access requests from a user or group of users based on parameters such as the user id, the time of access, the duration of access, and so on. In other embodiments, the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 may be configured to obtain all of the plurality of enforcement published on the policy bus 210, and analyze access requests from a user or group of users based on parameters from all or a subset of the policies.
Once the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 has selected or obtained a particular policy, they may be configured to analyze the information associated with the access request against the policy and determine if the user's access request is anomalous. In some embodiments, the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 may be configured to determine an anomalous request by determining deviation of the access request from the one or more data clusters generated by the analytics server 220 and machine learning component 225. If the deviation is beyond a predetermined threshold value, the request is determined to be anomalous. The threshold value can be determined by a user (e.g., an administrator) of system, or automatically by the analytics server 220 and machine learning component 225. In certain embodiments, the threshold value may be a mahalanobis distance that takes into account correlations of the data set for a cluster.
Each agent can react to a published policy in its own way to achieve the same end goal (e.g., not granting an unauthorized/unauthenticated user access to a protected resource). In certain embodiments, when an anomaly is detected and a policy to block a user is instituted (e.g., in STIX format) and published onto the policy bus 210, the one or more agents 235, one or more proxies 240, one or more access managers 245, and/or one or more Webgates 250 may select or obtain the policy and determine its role in blocking the user or group of users. For example, when the user or group of users is accessing an application, the one or more access managers 245 can be the entity that validates a user's credentials and authenticates the user to be part of an authenticated session, while the one or more agents 235, one or more proxies 240, and/or one or more Webgates 250 can initiate, maintain, or drop the session such that whenever a user is accessing a resource within any part of the enforcement ecosystem, the user may be challenged and validated. The one or more proxies 240 may constantly monitor and learn a user's or groups of users' activity as it is happening, and trigger an anomaly and take action such as a block on activity based on the policy. For instance, the one or more proxies 240 may obtain information of which user to block from a policy, and when a session request is received from an IP address that corresponds to the user, the one or more proxies 240 could block the initiating of the session. Thus, even if a resource is not protected by the other agents, the one or more proxies 240 have the same policy from the policy bus 210 and can take independent action on user activity.
Additionally or alternatively, the one or more agents 235, one or more access managers 245, and/or one or more Webgates 250 may constantly monitor and learn a user's or groups of users' activity as it is happening (e.g., when a user tries to type in a username or password on a login page, when the user is trying to access a protected application, or when the user is trying to access another website through an authorized session), and trigger an anomaly and take action such as a block on the activity based on the same policy. For instance, the one or more agents 235 and/or one or more Webgates 250 may check whether the session is still valid based on whether a time period has expired. In some instances, the time session will be valid for a predetermined period of time such as an hour or eight hours. The moment that session is invalid the user will be asked to login again. The one or more agents 235 and/or one or more Webgates 250 may try to validate the session using the policy and drop the session if the session is no longer valid. The one or more access managers 245 may also obtain the same policy and the next time the same user tries to login using the correct username and password the one or more access managers 245 may not grant the user access. Thus, even if a resource is not protected by one of the agents such as the one or more proxies 240, the one or more agents 235, one or more access managers 245, and/or one or more Webgates 250 have the same policy from the policy bus 210 and can take independent action on user activity. Accordingly, each of the agents reacts to the policy separately and differently, as opposed to conventional systems where the agents react as a group the same way once a rule is determined.
The consolidated user interface 280 may be presented to a security administrator when they log into the system. The consolidated user interface 280 may present the top users that are creating the network traffic and the sources that these users are accessing. Collected real-time data from the collection bus 205 may be fed into the system. The consolidated user interface 280 may present how often the user is accessing different sources on the network within a time period (e.g., 5 minute window, 30 minute window). The consolidated user interface 280 may be constantly updated as new data comes in, e.g., showing current minus 5 minutes. The top IP addresses that are active can also be shown. Some embodiments may show a correlation between the IP addresses that are highly active and the sources (e.g., URLs) that are popular and have a high traffic. Certain embodiments may also notate the IP addresses (e.g., using an asterisk) where the user has not been identified.
Some embodiments may present client IP address to application mapping in addition to user to application mapping. Certain embodiments may show that a particular IP address can be causing accesses to many different sources and vice versa where a particular URL are being accessed by all the different users. The consolidated user interface 280 presents the end users (or client IP addresses) on one side and the end sources on the other side. Some embodiments may also use colors to differentiate the groups. Certain embodiments may also present information such as the number of times that each application is being accessed. By selecting a particular user or client IP address, some embodiments may present the number of times that the particular user or client IP address has accessed the application.
Some embodiments enable an administrator via the consolidated user interface 280 to set one or more criteria for matching and values for the criteria. Certain embodiments also enable the administrator via the consolidated user interface 280 to specify the desired alert and duration for the alert if the one or more criteria and values for the criteria for an event match those specified by the administrator. For instance, some embodiments can match up the user and the client IP address and which destination (e.g., host name, particular IP address, services) this user is accessing, or match up the activity of the user, and provide a corresponding alert as designated by the administrator.

UIs 320, 325, 330, and 335 are coupled to one or more application servers 340 and 345 (e.g., analytics server 220, machine learning component 225, and visualization server 230 as described with respect to
Application servers 340 and 345 are coupled to database management system 350 (e.g., memory 255 as described with respect to
In various embodiments, the presentation layer 305, application layer 310 and database layer 315 operate to provide UIs 320, 325, 330, and 335, which comprise active threat categories, a count of policies being triggered for each threat category, and associated trends. As shown in
The buckets 405, 410, 415, 420, and 425 may include for each classification the total number of policies “n” 430 with the corresponding classification that are being triggered at any given time by user activity on the enterprise network. The buckets 405, 410, 415, 420, and 425 may further include for each classification associated trends in the number of policies “n” 430 that are being triggered. For example, graphics such as markers 435 and graphs 440 may be used to denote the historical trends for the number of policies “n” 430 that are being triggered. In some embodiments, if the number of policies “n” 430 that are being trigger is increasing (e.g., n+1, 5, 10, 15, etc.), then a up-arrow can be used to easily denote this trend. In contrast, if the number of policies “n” 430 that are being trigger is decreasing (e.g., n−1, 5, 10, 15, etc.), then a down-arrow can be used to easily denote this trend. If the number of policies “n” 430 that are being trigger, is substantially remaining the same (e.g., +/−5%, 10%, or 15%), then a circle can be used to easily denote this trend. In certain embodiments, the buckets 405, 410, 415, 420, and 425 may further include drop down boxes 445 that may be accessed by an administrator to investigate further into the details regarding the policies being triggered and the activity being performed by users (e.g., sources being accessed) on the enterprise network. In certain embodiments, the consolidated UI 400 further includes an additional bucket 450 for the total number of policies “m” (all classification groups) being acted upon at any given time.
In accordance with the various aspects discussed herein, user behavior on the enterprise network may be monitored and one or more dynamic policies may be created for the users. In some embodiments, an administrator or the machine learning component 225 can set an enforcement policy where certain actions would trigger a block, a second factor authentication, a low alert, a medium alert, or a high alert. For example, the machine learning component 225 can detect a variation or deviation of real-time data from historic data (e.g., a user typically accessing from home around 7 or 8 pm and today the user is accessing from somewhere else), and create a policy for this deviant access. The policy may designate this access with an alert level (e.g., low, medium, or high alert) or a second factor authentication or block designation. Based on whether the user is authenticated with the challenges presented through the second factor authentication, the system may use this historical data to modify the policy. If the alert level becomes escalated depending on the user's further actions and causes a new policy to designate the action as a high alert item, then the consolidated user interface 400 may start presenting the high alert action through the dashboard 402. If there is repeated high alerts from this user (e.g., 10 or 20 times) within a short period of time (e.g., last 10 seconds, last 20 seconds), then the machine learning component 225 may alert the administrator via the consolidated user interface 400 since it is likely that there is a problem.
In some embodiments, the dashboard 402 may have various windows 455 that display information including the top access activity, top users accessing sources, top IP addresses being used to access sources, and top sources being accessed. The top or bottom can be defined as a threshold number such as the top or bottom 5, 10, 15, 35, or 50. Alternatively, the top or bottom can be defined as a threshold percent such as the top or bottom 5%, 10%, 15%, 35%, or 50%. The windows 455 can display the information using any number of graphical means. For example, the top access activity can be displayed using pictogram or a line diagram 460 that illustrates a line connecting each user ID or IP address to a resource or target system being accessed. Additionally or alternatively, the top user can be displayed using a proportional area chart, a bubble chart, or a tag cloud 465 with changes in typography such as font size or color. Additionally or alternatively, the top IP addresses can be displayed using a proportional area chart, a bubble chart, or a tag cloud 470 with changes in typography such as font size or color. Additionally or alternatively, the applications can be displayed using a proportional area chart, a bubble chart, or a tag cloud 475 with changes in typography such as font size or color.
In some embodiments, the presentation layer 305, application layer 310 and database layer 315 may further operate to provide additional functionality or information for an administrator. For example,
In some embodiments, the presentation layer 305, application layer 310 and database layer 315 may further operate to provide additional functionality for an administrator to create one or more policies (e.g., inspection or enforcement policies).
In some embodiments, the presentation layer 305, application layer 310 and database layer 315 may further operate to provide additional functionality or information for an administrator. Some embodiments display to an administrator the number of a certain type of policies (e.g., block policies) during a specific time interval. Certain embodiments allow for an administrator to view which policies caused a certain action or alert (e.g., a block) (e.g., by selecting a UI element). For example,
By displaying various types of information to the administrator, the administrator can take appropriate action (e.g., in response to seeing different trends). The UIs described herein displaying an upward trend for certain alerts may enable the administrator to only need to react and take appropriate action when he sees an increasing trend of alerts. Some embodiments may enable an administrator to view which user/client IP address/source, was blocked by a high alert when going to a certain application, under a certain policy. When looking at policies, there are attributes that would enable an administrator to distinguish a manually injected policy against a machine learning policy. In some embodiments, an administrator may only be able to edit a manually created policy as opposed to a machine learning policy.
In various embodiments, an administrator may monitor the low, medium, and high alerts, and provide recommendations that certain policies causing the alerts may need to modified, for example, any high alerts may need to be modified for a block policy. Another system administrator may be notified of those policies that are recommended to be modified and make a determination as to whether to upgrade the policy to a block policy.
In various embodiments, the presentation layer 305, application layer 310 and database layer 315 operate to provide UIs 320, 325, 330, and 335, which comprise users, resources being acted upon by users, and the policies, if any, implicated by the such activity. As shown in
IV. Processes and Operations for Utilizing a Threat Intelligence Platform
The processes and/or operations depicted by in
At optional step 1910, an inspection policy can be created based on the historical data or specifications of a target system or resource. In some embodiments, the collection of data is triggered by an inspection policy published on a policy bus. For example, the collection bus may be configured to obtain the information associated with a security event such as an end user's access request and report the information or data on the report bus. The configuration of the collection bus may be based on default or static inspection policies comprising rules for collecting a predefined set of attributes (e.g., user attributes, resource attributes, object, actions, environment attributes, etc.) when certain criteria is satisfied. In certain embodiments, the system may provide an inspection policy UI that allows an administrator to create the inspection policy by designate the triggering of certain inspection policies when a set of criteria has been met (e.g., if header data matches, for a threshold time interval). In other embodiments, the configuration of the collection may be based on dynamic inspection policies comprising rules for collecting the data or attributes. For example, the collection bus and the analytics server may work together to collect the predefined set of attributes and trigger anomalies based on rules that were previously configured (default, static, or dynamic inspection and enforcement policies). The inspection policies includes rules for collecting the data in real-time, which is a predefined set of attributes pertaining to the security event, when a set of criteria for the security event match a predefined pattern. Once the data comes into the collection bus, it may be stored in memory and becomes part of historical data. The machine learning component can be constantly learning from the historical data and real-time data to create and modify the inspection and enforcement policies to efficiently collect information required for threat assessment of user activity on the system.
At optional step 1915, the inspection policy may be published or injected into the policy bus such that the plurality of agents have access to the inspection policy. Publishing the inspection policy on the policy bus facilitates the collection of data by allowing the listeners (i.e., the agents) to access the policies and enforce the policies to collect the predefined set of attributes based on rules that were previously configured. At step 1920, data may be collected pertaining to a security event. In various embodiments, the data includes: (i) a source that identifies a user or the user device, and (ii) a destination that identifies the target system or the resource. The data may be collected by the collection bus from at least one of the plurality of agents. In some embodiments, the data is collected in accordance with a default, static, or dynamic inspection policy dynamic inspection policy. For example, if criteria of a live information flow including a flow of data from a source to a destination, matches a predefined pattern with in the default, static, or dynamic inspection policy, then the inspection policy may be triggered and one or more agents may collect attributes (e.g., the source and destination) of the information flow or a security event occurring within the information flow. The collected attributes may then be sent to the collection bus for further processing in accordance with various aspects discussed herein.
At step 1925, a dynamic enforcement policy may be created based on the data. The dynamic enforcement policy includes at least a specification of the source, the destination, an enforcement action, and a duration for the dynamic enforcement policy to be active. The duration may be a predetermined period of time of at least 5 minutes, at least 10 minutes, at least 30 minutes, or at least on hour, for example, 10 minutes, 30 minutes, 1 hour, 5 hours, 1 day, or 3 days. During the duration for the dynamic enforcement policy to be active, the dynamic enforcement policy overwrites a static enforcement policy that includes a specification of at least the same source and the same destination. For example, a static enforcement policy may be default or active for a user or group of users from an IP address that requires a first level authentication, whenever any user from that IP address tries to access a resource on a specified target system. A dynamic enforcement policy may be published for a user or group of users from the same IP address that requires a second factor authentication, whenever any user from that IP address tries to access a resource on the same specified target system. The dynamic enforcement policy may have a duration of 5 hours. Accordingly, the static enforcement policy is inactive during the predetermined period of time (e.g., 5 hours), the dynamic enforcement policy is active (e.g., second factor authentication is enforced on requests from the IP address to the specified target system) during the predetermined period of time (e.g., 5 hours), the dynamic enforcement policy is rendered inactive and may be removed from the policy bus after the predetermined period of time has expired, and the static enforcement policy is active (e.g., first level authentication is enforced on requests from the IP address to the specified target system) after the predetermined period of time has expired.
In certain embodiments, the system may provide an enforcement policy UI that allows an administrator to create the dynamic enforcement policy by designate the triggering of certain enforcement actions when a set of attributes has been met (e.g., if a source and destination of a live information flows matches a source and destination of the policy). In other embodiments, the analytics server and a machine learning component create the dynamic enforcement policy. The creating the dynamic enforcement policy may comprise: classifying the data collected in real-time and historical data into one or more data clusters, analyzing the predefined set of attributes using the one or more data clusters, and creating the source, the destination, the enforcement action, and the duration for the dynamic enforcement policy to be active based on the analysis. The one or more data clusters may be generated using supervised or unsupervised machine learning or clustering techniques, and the analyzing may include calculating a distance of the predefined set of attributes from a centroid of the one or more data clusters. The enforcement action such as a block or second factor authentication may be determined based on the distance of the predefined set of attributes from the centroid of the one or more data clusters.
At step 1930, the dynamic enforcement policy may be published on the policy bus such that the plurality of agents have access to the dynamic enforcement policy. Publishing the dynamic enforcement policy on the policy bus facilitates threat detection on for example an enterprise network by allowing the listeners (i.e., the agents) to access the policies and activate enforcement actions of the policies based on rules that were previously configured. At step 1935, the enforcement action for the security event may be implemented based on the dynamic enforcement policy. In some embodiments, at least one of the plurality of agents implements the enforcement action. The enforcement action may be implemented by at least one of the plurality of agents determining that attributes (e.g., a source and destination) of the information flow or a security event occurring within the information flow match the attributes (e.g., the source and destination) within the specification of the dynamic enforcement policy. Thereafter, the enforcement action may be implemented by at least one of the plurality of agents performing the enforcement action, for example, (i) blocking user access to the destination prior the user being authorization for access, (ii) dropping connection of the user with the destination, (iii) blocking authentication of the user on the system, (iii) requesting second factor authentication or authorization, (iv) reporting a low alert, medium alert, or high alert, etc.
At step 2010, one or more live information flows may be monitored. The live information flows may include flows of data from a plurality of sources to a plurality of destinations. In some embodiments, the monitoring is performed by the plurality of agents. The monitoring may be performed in accordance with various policies (e.g., inspection and enforcement policies). At step 2015, a user interface may be provide that includes a plurality of buckets. Each bucket may be associated with a different threat level or enforcement action, and each bucket displays a total number of enforcement policies presently triggered in real-time that include the associated threat level or enforcement action. In essence, the buckets are graphical silos classified in accordance with the same classification scheme (e.g., block, second factor authentication, low alert, medium alert, high alert, etc.) assigned to the enforcement policies based on the threat level or enforcement action declared in each policy, as shown in
At step 2020, an occurrence of a security event is determined within the one or more live information flows based on a trigger of an enforcement policy. The enforcement policy may include a specification of a source, a destination, and an enforcement action, and when the data within the one or more live information flows matches at least the source and the destination of the enforcement policy, the enforcement policy is triggered and the enforcement action is applied. At step 2025, the user interface may be updated to reflect the occurrence of the security event by: (i) identifying a bucket from the plurality of buckets that is associated with the enforcement action applied by the enforcement policy, and (ii) increasing the total number of enforcement policies presently triggered in real-time by the enforcement action and displayed within the identified bucket. In some embodiments, the increasing the total number of enforcement policies includes incrementing a count n for the total number of enforcement policies to a count of n+1. Optionally, at step 230, a trend indicator for the identified bucket may be updated based on the occurrence of the security event. For example, updating the trend indicator may comprise displaying an up-arrow, down-arrow, or neutral circle within the identified bucket.
Optionally, at step 2035, a user input may be received corresponding to a selection of a bucket from the plurality of buckets. In some embodiments, in response to the selection, the live information flows including the plurality of sources and the plurality of destinations corresponding to the selected bucket may be displayed within the user interface. In other embodiments, in response to the selection, the plurality of sources corresponding to the selected bucket may be display within the user interface as a tag cloud. The tag cloud may illustrate the plurality of sources corresponding to the selected bucket proportionally based on activity of each source.
Optionally, at step 2040, a user input may be received corresponding to a selection of a particular source from the plurality of sources. In some embodiments, in response to the selection, the live information flows starting at the particular source are displayed.

In some embodiments, in response to the selection, the live information flows ending at the particular destination are displayed. Optionally, at step 2050, the live information flows including the plurality of sources and the plurality of destinations may be displayed within the user interface. In some embodiments, an indication of a set of top sources may be provided based on an amount of the data flowing from the plurality of sources to the plurality of destinations.

In some embodiments, an indication of a set of top destinations may be provided based on an amount of the data flowing from the plurality of sources to the plurality of destinations. Optionally, at step 2060, the live information flows including the plurality of sources and the plurality of destinations may be displayed within the user interface. In some embodiments, an indication of a set of top enforcement policies may be provided based on an amount of the data flowing from the plurality of sources to the plurality of destinations, and a set of active enforcement policies published on the policy busy.
Optionally, at step 2065, a request to create a dynamic enforcement policy may be received based on the data. The dynamic enforcement policy may include a specification of a source, a destination, an enforcement action, and a duration for the dynamic enforcement policy to be active. Optionally, at step 2070, the dynamic enforcement policy may be published on a policy bus such that a plurality of agents have access to the dynamic enforcement policy. As discussed herein, the duration may be a predetermined period of time of at least 5 minutes, at least 10 minutes, at least 30 minutes, or at least on hour, for example, 10 minutes, 30 minutes, 1 hour, 5 hours, 1 day, or 3 days. During the duration for the dynamic enforcement policy to be active, the dynamic enforcement policy overwrites a static enforcement policy that includes a specification of at least the same source and the same destination. Optionally, at step 2075, the enforcement action may be implemented for another security event within the one or more live information flows based on the dynamic enforcement policy. At least one of the plurality of agents may implement the enforcement action. Optionally, at step 2080, the user interface may be updated to reflect the implementation of the enforcement action for the another security event by: (i) identifying a bucket from the plurality of buckets that is associated with the enforcement action applied by the dynamic enforcement policy, and (ii) increasing the total number of enforcement policies presently triggered in real-time by the enforcement action and displayed within the identified bucket.
At step 2110, a live information flow may be monitored. The live information flow may include a flow of data from a source to a destination. In some embodiments, the monitoring is performed by the plurality of agents. The monitoring may be performed in accordance with various policies (e.g., inspection and enforcement policies). Optionally, at step 2115, one or more live information flows may be monitored. For example, one or more additional live information flows may be monitored. The additional live information flows may include: (i) flows of data from a plurality of sources to a plurality of destinations, and (ii) one or more enforcement policies triggered by the data. At step 2120, a user interface may be provide that includes the source and the destination connected via a line. For example, each source included within live information flows may be connected via a graphical line to one or more destinations being accessed, as shown in
At step 2125, an occurrence of a security event may be determined within the live information flow based on a trigger of an enforcement policy. The enforcement policy may include a specification of the source, the destination, and an enforcement action, and when the data within the one or more live information flows matches at least the source and the destination of the enforcement policy, the enforcement policy is triggered and the enforcement action is applied. At step 2130, the user interface may be updated to reflect the occurrence of the security event by: (i) identifying an indicator of the enforcement policy, and (ii) displaying the line connecting the source and the destination running through the indicator of the enforcement policy. In some embodiments, the source is displayed on one side of a window of the user interface, the destination is displayed on a side of the window opposite the side having the source, and the indicator of the enforcement policy is displayed on the line between the source and the destination.
Optionally, at step 2135, a user input may be received corresponding to a selection of a particular source from the plurality of sources. In some embodiments, in response to the selection, the live information flows starting at the particular source including the one or more enforcement policies triggered by the data within the live information flows are displayed. Optionally, at step 2140, a user input may be received corresponding to a selection of a particular destination from the plurality of destinations. In some embodiments, in response to the selection, the live information flows ending at the particular destination including the one or more enforcement policies triggered by the data within the live information flows are displayed. Optionally, at step 2145, the live information flows including the plurality of sources and the plurality of destinations may be displayed within the user interface. In some embodiments, an indication of a set of top sources may be provided based on an amount of the data flowing from the plurality of sources to the plurality of destinations.

Optionally, at step 2160, a request to create a dynamic enforcement policy may be received based on the data. The dynamic enforcement policy may include a specification of a source, a destination, an enforcement action, and a duration for the dynamic enforcement policy to be active. Optionally, at step 2165, the dynamic enforcement policy may be published on a policy bus such that a plurality of agents have access to the dynamic enforcement policy.

In addition to services related to identity management, various other services may also be offered including without limitation online data storage and backup solutions, Web-based e-mail services, hosted office suites and document collaboration services, database processing, managed technical support services, and the like. Services provided by the cloud infrastructure system can dynamically scale to meet the needs of its users.
In certain embodiments, a specific instantiation of a service provided by cloud infrastructure system 2302 may be referred to herein as a “service instance.” In general, any service made available to a user via a communication network, such as the Internet, from a cloud service provider's system is referred to as a “cloud service.” Typically, in a public cloud environment, servers and systems that make up the cloud service provider's system are different from the customer's own on-premises servers and systems. For example, a cloud service provider's system may host an application, and a user may, via a communication network such as the Internet, on demand, order and use the application.
In some examples, a service in a computer network cloud infrastructure may include protected computer network access to storage, a hosted database, a hosted web server, a software application, or other service provided by a cloud vendor to a user, or as otherwise known in the art. For example, a service can include password-protected access to remote storage on the cloud through the Internet. As another example, a service can include a web service-based hosted relational database and a script-language middleware engine for private use by a networked developer. As another example, a service can include access to an email software application hosted on a cloud vendor's web site.
In certain embodiments, cloud infrastructure system 2302 may include a suite of applications, middleware, and database service offerings that are delivered to a customer in a self-service, subscription-based, elastically scalable, reliable, highly available, and secure manner. An example of such a cloud infrastructure system is the Oracle Public Cloud provided by the present assignee.
Cloud infrastructure system 2302 may also provide “big data” related computation and analysis services. The term “big data” is generally used to refer to extremely large data sets that can be stored and manipulated by analysts and researchers to visualize large amounts of data, detect trends, and/or otherwise interact with the data. This big data and related applications can be hosted and/or manipulated by an infrastructure system on many levels and at different scales. Tens, hundreds, or thousands of processors linked in parallel can act upon such data in order to present it or simulate external forces on the data or what it represents.
