Abstract: Described is a technology by which access to a resource is determined by evaluating a resource label of the resource against a user claim of an access request, according to policy decoupled from the resource. The resource may be a file, and the resource label may be obtained by classifying the file into classification properties, such that a change to the file may change its resource label, thereby changing which users have access to the file. The resource label-based access evaluation may be logically combined with a conventional ACL-based access evaluation to determine whether to grant or deny access to the resource.

Abstract: Providing services within a network of service providers sharing an authentication service and a set of business rules. A central server receives a first request from a first server to provide a first service to a user via a client without forcing the user to present credentials. In response to the received first request, the central server stores data identifying the first service on the client. The central server further receives a second request from a second server to provide a second service to the user via the client after the user presents the credentials to the second service. After receiving the second request and the presented credentials, the central server allows the user access to the second service. In response to allowing the user access to the second service, the central server further allows the user access to the first service as a result of the stored data.

Abstract: Described is a technology, such as implemented in an operating system security system, by which a resource's metadata (e.g., including data properties) is evaluated against an audit rule or audit rules associated with that resource (e.g., object). The audit rule may be associated with all such resources corresponding to a resource manager, and/or by a resource-specific audit rule. When a resource is accessed, each audit rule is processed against the metadata to determine whether to generate an audit event for that rule. The audit rule may be in the form of one or more conditional expressions. Audit events may be maintained and queried to obtain audit information for various usage scenarios.

Abstract: Existing mechanisms that control access to data based upon whether the user seeking to access the data is identified among the users that are allowed to access the data, can be extended to further control access based upon the provision of credential data by the user, or processes associated therewith. Access control entries can limit access based upon Boolean conditionals, including those referencing credential data, such that access can be granted only to specific users that provide the credential data or, alternatively, to any user that provides it. The referenced credential data can be specified in the access control information in an obfuscated form for security purposes. Information associated with the user, such as a user token, can be temporarily updated to include credential data when provided by the user, so as to enable access to the data but to prevent such access from remaining open too long.

Abstract: Abstracting access control policy from access check mechanisms allows for richer expression of policy, using a declarative model with semantics, than what is permitted by the access check mechanisms. Further, abstracting access control policy allows for uniform expression of policy across multiple access check mechanisms. Proof-like reasons for any access query are provided, such as who has access to what resource, built from the policy statements themselves, independent of the access check mechanism that provide access. Access is audited and policy-based reasons for access are provided based on the access control policy.

Abstract: Creating an account via a mobile device. A request to create an account is received from a user via a mobile device. The request is received from the mobile device according to a wireless communications protocol. In response to the received request, a confirmation message is delivered to the mobile device for rendering to the user as a challenge. A response to the rendered challenge is received from the user via the mobile device. It is determined if the received response to the rendered challenge corresponds to the delivered confirmation message. And the account is created for the user if the received response to the rendered challenge is determined to correspond to the delivered confirmation message. Other aspects of the invention are directed to computer-readable media for use with account creation via a mobile device.
