Mandatory access control list for managed content
View Patent ↗Restricting access to managed content to users that are both ( 1 ) members of one or more required groups identified in an ACL associated a content item to which access is requested and ( 2 ) otherwise granted access under the ACL, e.g., by virtue of their individual identity, role, or group membership is disclosed. In some embodiments, an ACL is configured to identify one or more groups as being a “required” group, membership in which is required for a user to be granted access to a content item with which the ACL is associated. If a user is not a member of a required group, the user is denied access (or denied access above a certain level), even if the user is otherwise delegated access rights in the ACL.
1. A method of controlling access to managed content, comprising:
receiving at a content management system a request associated with a user to access a content item included in a body of managed content;
reading an access control list associated with the content item;
determining at the content management system whether the user is granted an access right based on one or more entries included in the access control list;
determining at the content management system whether the user is a member of an aggregated required group, comprising one of the following:
determining the aggregated required group based on one individual required group if the access control list includes only one individual required group; and
determining the aggregated required group by combining two or more individual required groups using one or more AND operations or OR operations if the access control list includes two or more individual required groups; and
providing access to the user if the user is granted the access right and further is a member of the aggregated required group.
2. The method as recited in claim 1 , wherein the request is received from an application running on a framework associated with the content management system.
3. The method as recited in claim 1 , wherein the determination whether the user is a member of the aggregated required group is made by business logic associated with the content management system.
4. The method as recited in claim 1 , wherein determination whether the user is a member of the aggregated required group is based at least in part on one or more of the following: an individual identity of the user, a security classification or level of the user, a group of which the user is a member, a role associated with the user, a supplemental security classification associated with the user, a session data associated with the user, and a session data associated with the request.
5. The method as recited in claim 1 , wherein the requested access comprises one or more of the following types of access: browse, read, relate, version, write, and delete.
6. A content management system, comprising:
a communication interface configured to receive a request to access a content item included in a body of managed content; and
a processor coupled to the communication interface and configured to:
read an access control list associated with the content item;
determine at the content management system whether the user is granted an access right based on one or more entries included in the access control list;
determine at the content management system whether the user is a member of an aggregated required group, comprising one of the following:
determine the aggregated required group based on one individual required group if the access control list includes only one individual required group; and
determine the aggregated required group by combining two or more individual required groups using one or more AND operations or OR operations if the access control list includes two or more individual required groups; and
provide access to the user if the user is granted the access right and further is a member of the aggregated required group.
7. The system as recited in claim 6 , further comprising a content store configured to store the content item.
8. The system as recited in claim 6 , further comprising a metadata store configured to store the access control list and a linking data associating the access control data with the content item.
9. A computer program product for controlling access to managed content, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions which when executed by a computer cause the computer to perform the steps of
receiving at a content management system a request to access a content item included in a body of managed content;
reading an access control list associated with the content item;
determining at the content management system whether the user is granted an access right based on one or more entries included in the access control list;
determining at the content management system whether the user is a member of an aggregated required group, comprising one of the following:
determining the aggregated required group based on one individual required group if the access control list includes only one individual required group; and
determining the aggregated required group by combining two or more individual required groups using one or more AND operations or OR operations if the access control list includes two or more individual required groups; and
providing access to the user if the user is granted the access right and further is a member of the aggregated required group.
10. The computer program product as recited in claim 9 , wherein determination whether the user is a member of the aggregated required group is based at least in part on one or more of the following: an individual identity of the user, a security classification or level of the user, a group of which the user is a member, a role associated with the user, a supplemental security classification associated with the user, a session data associated with the user, and a session data associated with the request.
11. The method as recited in claim 1 , wherein determining whether the user is a member of the aggregated required group comprises using session data.
12. The system as recited in claim 6 , wherein determining whether the user is a member of the aggregated required group comprises using session data.
13. The computer program product as recited in claim 9 , wherein determining whether the user is a member of the aggregated required group comprises using session data.
14. The system as recited in claim 6 , wherein the request is received from an application running on a framework associated with the content management system.
15. The system as recited in claim 6 , wherein the determination whether the user is a member of the aggregated required group is made by business logic associated with the content management system.
16. The system as recited in claim 6 , wherein determination whether the user is a member of the aggregated required group is based at least in part on one or more of the following: an individual identity of the user, a security classification or level of the user, a group of which the user is a member, a role associated with the user, a supplemental security classification associated with the user, a session data associated with the user, and a session data associated with the request.
17. The system as recited in claim 6 , wherein the requested access comprises one or more of the following types of access: browse, read, relate, version, write, and delete.
