12126620
The present disclosure relates to secure system access control, and more specifically, to delegation of access permission for secure systems.
Occasionally, situations arise that require an account owner to share access to their account on a secure system. For example, an account owner may need to share access with a colleague, customer, or family member. Some systems have a delegation feature that allows users to temporarily share their secure system privileges with others. However, not all systems provide such a delegation feature.
According to embodiments of the present disclosure, a computer-implemented method is provided. The method includes receiving a request for access to a secure system using an owner's account from an applier via a browser supplement module on the applier's computing device. The request is communicated to the account owner via a browser supplement module on the account owner's computing device. Approval of the request is received from the account owner. The secure system is logged into using the account owner's credential. A connection to the applier's computing device is established to act as a proxy for communication between the secure system and the applier's computing device. Further provided herein are a computer system and a computer program product for performing the method.
The above summary is not intended to describe each illustrated embodiment or every implementation of the present disclosure.
The drawings included in the present application are incorporated into, and form part of, the specification. They illustrate embodiments of the present disclosure and, along with the description, serve to explain the principles of the disclosure. The drawings are only illustrative of certain embodiments and do not limit the disclosure.
While the invention is amenable to various supplements and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all supplements, equivalents, and alternatives falling within the spirit and scope of the invention.
Aspects of the present disclosure relate to secure system account delegation, and more particular aspects relate to browser supplement modules for secure system account delegation. While the present disclosure is not necessarily limited to such applications, various aspects of the disclosure may be appreciated through a discussion of various examples using this context.
When account owners don't have access to a delegation feature, they tend to share their credentials with others. This introduces security risks and the account owner's control over their account.
Embodiments of the present disclosure may provide for account delegation without revealing the owner's credentials to other users. Using a browser supplement module, an applier can send a request to an account owner to access the owner's secure system account. The browser supplement module may be a piece of software that extends the functionality of a browser, such as a plugin, extension, add-on, etc. Thus, embodiments of the present disclosure may be implemented for systems that do not have a delegation feature. With the account owner's approval, the applier may be given access to a secure system via a delegation system (centralized) or a browser supplement module on the account owner's system (decentralized). In centralized embodiments, the delegation system may use access control, certificates, single sign on (SSO), etc. to identify users. In decentralized embodiments, the owner's system may use certificates, Oauth, SSO, etc. to identify requesters.
In centralized embodiments, each user of the delegation system may install and activate a browser supplement module on their computer system to act as a client of a delegation system. Upon activation of the browser supplement module, an account owner may enter user information into the browser supplement module to register with an account delegation server. The user information may include a user account name for a secure system. For example, a user account name could be in the format username@domain.com. The account owner's browser supplement module may send the user information for the account owner and an Internet Protocol (IP) address for the account owner's computer system to the account delegation server. The account delegation server may store the user information and IP address for later use. When an applier wants to access the owner's account on the secure system, they may enter the user information for the owner (e.g., in the format owner@securesystem.com) into the browser supplement module on their computer system and the browser supplement module may send a request to the account delegation server with the user information. The account delegation server may use the user information to identify the IP address of the account owner's computer system. The account delegation server may map the IP address and send the applier's request to the account owner. The account owner's browser supplement module may receive the request and prompt the account owner to approve the request. The account owner may approve the request and enter their credential into the browser supplement module. The browser supplement module may communicate the account owner's credential to the account delegation server. The account delegation server may login to the secure system using the account owner's credential and establish a connection with the applier system to act as a proxy for communication between the applier and the secure system. The account delegation server may maintain a log of the applier's actions using the secure system while acting as proxy. The owner may use the browser supplement module to access the log and stop the connection when they choose.
In decentralized embodiments, each user of the delegation system may install and activate a browser supplement module to act as a system agent. An applier may enter an IP address and user information for an account owner into their browser supplement module (e.g., in the format owner@domain.com/192.168.10.1). The applier's browser supplement module may map the IP address and send a request to access a secure system with the user information to the account owner's computer system. In response to receiving the request, the account owner's browser supplement module may prompt the account owner to approve the request. The account owner may approve the request and log in to the secure system using the account owner's credential. The account owner's browser supplement module may establish a connection with the applier's system and act as a proxy for communication between the applier and the secure system. The account owner's browser supplement module may log actions taken by the applier using the secure system.

Delegation system 110 may be computing system, such as a server, configured to provide secure system account delegation for an account owner using owner system 120 and an applier using applier system 130. Delegation system 110 may be configured to communicate over one or more networks with owner system 120, applier system 130, and secure system 140. Delegation system 110 includes user information storage 112. User information storage 112 may store user information such as user addresses (e.g., IP addresses) and user identification (such as a username for the secure system 140). User information storage 112 may be any suitable storage device. In some embodiments, user information storage 112 may be an external storage, such as a database, in communication with delegation system 110. Delegation system 110 may also store a log 116. Delegation system 110 may store, in log 116, actions taken by a user of applier system 130 while accessing another user's secure system account using the delegation system. Log 116 may be stored in any suitable storage device. In some embodiments, log 116 may be stored in the same storage device as user information storage 112.
Owner system 120 includes a browser 124 and browser supplement module 128. Applier system 130 also includes a browser 134 and browser supplement module 138. Browser supplement modules 128 and 138 may be configured to provide additional functionality to browsers 124 and 134, respectively, to have them function as clients of delegation system 110. Browser supplement modules 128 and 138 may be configured to communicate with delegation system 110 for user registration and secure system account delegation for secure system 140. Browsers 124 and 134 may be the same type of browser or may be different. In some embodiments, the browser supplement module is the same for an applier and an owner. For example, owner system 120 and applier system 130 may be essentially the same, with either system capable of requesting access to a secure system account of a user of the other system. In other embodiments, a different browser supplement module may be used to implement functions for the account owner of a secure system than the functions for an applier to use an account owner's secure system account. While two user systems and one secure system are depicted, embodiments could include any number of user systems and any number of secure systems.

Prior to executing method 300, account delegation system 110 may collect user information from owner system 120 during a registration process. The registration process may occur in response to a user of owner system 120 activating browser supplement module 128. Upon activation, browser supplement module 128 may cause owner system 120 to communicate user information to delegation system 110 over one or more networks. For example, owner system 120 may communicate user identification and an address (such as an IP address) for owner system 120. Browser supplement module 128 may prompt the account owner to enter their user identification for the account to send it to delegation system 110.
At operation 310, the account delegation system 110 receives a request from applier system 130 to log in to the secure system 140 as the account owner. An applier may input a user identification (such as a username for the secure service account) into browser supplement module 138 and the module may cause applier system 130 to communicate the request with the user identification over one or more networks to delegation system 110. The applier may also enter a specific secure system, such as secure system 140, and the module may include the specific secure system in the request.
At operation 320, the account delegation system 110 may request approval for the request from the owner. In some embodiments, the account delegation system may identify an IP address for the user in user information storage 112 using a user identification provided in the applier's request. The account delegation system 110 may map the IP address and communicate the request to owner system 120. In response to receiving the request, browser supplement module 128 may prompt the owner to approve or deny the request.
At operation 330, the account delegation system 110 determines whether the request was approved. In some embodiments, the request may be denied by receiving a communication from owner system 120 indicating that the request is denied. For example, the owner may select option provided by browser supplement module 128 to deny the request and the module may cause owner system 120 to communicate the denial of the request to delegation system 110. In some embodiments, the request may be determined to be denied if no response is received from owner system 120 within a specified period of time. In response to the request being denied, account delegation system 110 may communicate the denial of the request to applier system 130 at operation 340.
The account delegation system 110 may determine that the request has been approved if a communication indicating that the request has been approved is received from owner system 120. In some embodiments, the communication from owner system 120 may include a credential for connecting to the owner's account on secure system 140. At operation 330, if the account delegation system 110 determines that the request has been approved, the account delegation system may connect to the secure system using the owner's credential at operation 350. In some embodiments, the credential may be received from owner system 120 with the approval of the request. In some embodiments, the credential may be retrieved from user information storage 112 if it was provided by the owner system 120 during registration.
At operation 360, account delegation system 110 establishes a connection with applier system 130 and acts as a proxy for communication between applier system 130 and secure system 140.
At operation 370, account delegation system 110 maintains a log 116 of actions taken by applier system 130 over the connection. The owner may request the log to review the actions that were taken by the applier while accessing the owner's account.
Method 300 will now be described in reference to decentralized delegation environment 200. At operation 310, owner system 220 receives a request to access secure system 240 from applier system 230. In some embodiments, an applier may enter user information for the account owner and the IP address for owner system 220 into browser supplement module 238. In response, browser supplement module 238 may map the IP address and cause applier system 230 to communicate the request to owner system 220 over one or more networks. The request may include the user information, such as a username, that identifies the account that the applier wants to access. In some embodiments, the applier further identifies secure system 240 in browser supplement module 238 and browser supplement module 238 includes the identification of secure system 240 in the request to owner system 220.
At operation 320, owner system 220 requests approval of the request from the owner of the account. In some embodiments, browser supplement module 228 may display the request information to the account owner including, for example, identification of the applier, user information for the account, and identification of the secure system. The account owner may approve the request and input their credential into browser supplement module 228 or may deny the request.
At operation 330, owner system 220 determines whether the request has been approved. If the owner has denied the request, owner system 220 may communicate the denial to applier system 230 at operation 340. If the owner approves the request, owner system 230 may establish a connection with secure system 240 using the owner's credential at operation 350.
At operation 360, owner system 220 establishes a connection with applier system 230 to act as a proxy for communications between applier system 230 and secure system 240.
At operation 370, owner system 220 maintains a log 216 of actions taken by applier system 230 over the connection to secure system 240.

In the foregoing, reference is made to various embodiments. It should be understood, however, that this disclosure is not limited to the specifically described embodiments. Instead, any combination of the described features and elements, whether related to different embodiments or not, is contemplated to implement and practice this disclosure. Many modifications and variations may be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. Furthermore, although embodiments of this disclosure may achieve advantages over other possible solutions or over the prior art, whether or not a particular advantage is achieved by a given embodiment is not limiting of this disclosure. Thus, the described aspects, features, embodiments, and advantages are merely illustrative and are not considered elements or limitations of the appended claims except where explicitly recited in a claim(s).
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.
