Patent Application
20130239166
Large scale system operation may be provided. Security and privacy are primary concerns Software as a Service (SaaS) systems. Customers want service providers to operate with a very low human touch and a minimum number of operators and engineers with potential access to customer data. Conventional approaches for this problem are to segregate access and ensure that users who need full administrator access have gone through complete background clearance. Such approaches must also assume good intentions on the part of those users, who are provided standing persistent permissions.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter. Neither is this Summary intended to be used to limit the claimed subject matter's scope.
Large scale system operation may be provided. Upon receiving an action request from a user, a determination may be made as to whether the user requires elevated permissions to perform the action request. In response to determining that the user requires elevated permissions to perform the action request, the action request may be forwarded to a lockbox for evaluation and a permission response may be received from the lockbox.
Both the foregoing general description and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing general description and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.
The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate various embodiments of the present invention. In the drawings:
The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the invention may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the invention.
Large scale system operation may be provided. Administrative access to systems used to provide cloud services may be regulate to ensure that there are no unauthorized access or exposure to the customer generated data. Furthermore, full auditing and reporting of all administrator activity and/or access may be provided. Such access management may be fully automated to grant, monitor, revoke and report access based on the needs of operating a large scale service and/or a complex on-premise system.
By default, everyone who has access to operate the service, debug issues, and/or respond to escalations and incidents in the system may be provided configuration view only permissions. Nobody in the system may belong to a full administrator and/or other elevated permissions security group. When an elevated access is needed, as when making a change in the system as a corrective action and/or to do invasive debugging of customer specific issues, the user may be expected to submit a request to an on-demand elevation system such as a lockbox.
The lockbox may evaluate the role of the requestor and the role group that they are requesting access to with a set of pre-defined policies. The lockbox may then make a decision either to automatically elevate and/or request explicit approval from an approval body as dictated by the policies. During elevation, the lockbox may stamp an attribute in the user object with an expiry time based on a requested interval. This lockbox may automatically de-elevate at a configured interval by default. The lockbox policies may also allow for elevation for a requested period of time. A de-elevate component of the lockbox may execute at configurable intervals looking for folks to be de-elevated.
All the activity on elevation requests may be audited and monitored. The lockbox may grant permissions at a granular level that segregates the duties and ensures that malicious activity can't happen. For example, those with permissions to change a configuration that is potentially exposing customer data do not have permissions to wipe off the audit trail of such change. The lockbox may monitor account usage and automatically disables user accounts inactive accounts and/or accounts associated with users who no longer have rights to access the services system.
Method 200 may then advance to stage 215 where computing device 300 may determine whether the requested action requires an elevated permission. For example, on-call engineer 140 may have basic permission to view a log entry, but restarting software service 120(B) may require an elevated permission.
In response to determining that the requested action requires the elevated permission, method 200 may advance to stage 220 where computing device 300 may determine whether the action request complies with at least one of a plurality of permission policies associated with a lockbox service. For example, the requested action may be forwarded to lockbox component 115 and checked for compliance with at least one permission policy of plurality of permission policies 135 by permission module 125. Such policies may comprise checks for factors such as a user group criterion, a security flag criterion, an action scope criterion, and a schedule criterion. For example, a user may belong to an “onsite” user group that allows greater automated elevation of permissions that a user accessing server 110 from offsite.
Method 200 may then advance to stage 225 where computing device 300 may grant the elevated permission to the user. For example, lockbox component 115 may elevate the permissions allocated to on-call engineer 140 in order to allow the requested action to be performed. This elevation may be for a limited duration, that may be defined, for example, by the permission policy, by a configuration setting associated with the software service, and/or by a configuration setting associated with the at least one user group. Such permissions may comprise a set of permissions associated with a task, such as the need to modify overall configuration data for server 110 and restart several core services (e.g., network and/or user management services) in order to install a new software service into production.
If the action request is determined not to comply with the permission policies, method 200 may advance to stage 227 where computing device 300 may forward the action request to at least one approval user. For example, lockbox component 115 may forward the request to administrator 150 for review.
After elevating the access at stage 225, or if the requested action is determined not to need elevated access at stage 215, method 200 may advance to stage 230 where computing device 300 may perform the requested action. For example, on-call engineer 140 may be allowed to perform a debugging trace as allowed by the newly elevated permissions.
Method 200 may then advance to stage 235 where computing device 300 may create a log entry of the action request. The log entry may comprise whether the request resulted in automatic approval of the permissions elevation at stage 225 and/or whether the request was sent for administrator approval at stage 227. The log entry may further comprise a record of data accessed by the requesting user while the elevated permissions were in force. Consistent with embodiments of the invention, users who receive elevated permissions that permit access to user data 122(A)-(C) may be denied, by policies 135, if they request an action to modify log entries associated with such access. Such denials may also be logged and/or forwarded to administrator 150.
Method 200 may advance to stage 240 where computing device 300 may determine whether any users currently granted at least one second elevated permission should have those permissions revoked. For example, policies 135 may define a configurable length of time that such elevations are to remain in effect.
In response to identifying a user that should have their elevated permission revoked, method 200 may advance to stage 245 where computing device 300 may revoke the elevated permission and/or restore the user to only basic level access.
After revoking the elevated permissions at stage 245, or if no users were found to need permissions revoked at stage 240, method 200 may advance to stage 250 where computing device 300 may detect whether any users should have all access revoked. For example, a user who has been inactive for a configurable length of time or a user who is no longer employed by an organization associated with operating multi-tenant server 110 may be identified as candidates for removal.
In response to determining that the identified user should be removed, such as where the user is no longer associated with one of software services 120(A)-(C), method 200 may advance to stage 255 where computing device 300 may remove the user's access. For example, the user may be removed from the basic level user group and may have their access, including the ability to request actions, revoked.
Method 200 may then advance to stage 260 where computing device 300 may provide an audit report. For example, administrator 150 may be provided with an audit report comprising a list of all users who have been granted elevated permissions that allow access to user data 122(A)-(C). Method 200 may then end at stage 265.
An embodiment consistent with the invention may comprise a system for providing large scale system operation. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive an action request from a user, determine whether the user requires elevated permissions to perform the action request, and in response to determining that the user requires elevated permissions to perform the action request, forward the action request to a lockbox and receive a permission response from the lockbox. In response to determining that the permission response comprises the approval, the processing unit may be operative to grant the user temporary elevated permission to perform the requested action. The permission response may be the result of the processing unit applying one of a plurality of permission policies that may each comprise a plurality of pre-defined evaluation rules, such as a rule associated with the user's role and/or user group membership (e.g., an onsite and/or on-call operator), an expiration rule (e.g., how long an elevated permission may persist), a security flag rules (e.g., whether the user's account indicates that the user has undergone a security clearance and/or background check), and an action request evaluation rule that may determine whether the requested action violates a privacy policy (e.g., denying elevations that may allow the user to modify a log entry associated with their own actions.)
Another embodiment consistent with the invention may comprise a system for providing large scale system operation. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive an action request requiring an elevated permission from a user and determine whether the action request complies with at least one of a plurality of permission policies. In response to determining that the action request complies with the at least one of the plurality of permission policies, the processing unit may be operative to grant the user an elevated permission to perform the requested action. Otherwise, the processing unit may be operative to forward the action request to at least one approval user. The processing unit may be further operative to provide an audit report comprising a plurality of log entries associated with requested actions from various users. The granted elevated permissions may comprise, for example, a set of permissions for various actions associated with a task such as deploying a new software service to production on a cloud server.
Yet another embodiment consistent with the invention may comprise a system for providing large scale system operation. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive an action request from a user and determine whether the requested action requires an elevated permission. In response to determining that the requested action requires the elevated permission, the processing unit may be operative to determine whether the action request complies with at least one of a plurality of permission policies associated with a lockbox service and, if not, forward the action request to at least one approval user. Otherwise, the processing unit may be operative to grant the elevated permission to the user for a limited duration, perform the requested action, and create a log entry associated with the user and the requested action. The processing unit may be further operative to periodically determine whether any users currently granted elevated permissions should have those elevated permissions revoked, such as after an expiration time defined by one of the permission policies and, if so, revoke the elevated permissions. The processing unit may be further operative to periodically detect whether any users are no longer associated with the at least one software service, such as where an operator is moved to a new project and/or leaves the organization associated with supporting the software service and, if so, remove the at least one third user from the at least one user group. The processing unit may also be operative to provide an audit report comprising a plurality of log entries associated with a plurality of requested actions.
