Abstract

A system and method for authorization to adaptively control access to a resource, comprising the steps of providing for the mapping of a principal to at least one role, wherein the at least one role is hierarchically related to the resource; providing for the evaluation of a policy based on the at least one role; and providing for the determination of whether to grant the principal access to the resource based on the evaluation of the policy.

Claims

1. A computer readable medium having instructions stored thereon that when executed by a processor cause a system to:

map a principal to at least one role, wherein the at least one role is hierarchically related to the resource, the resource being part of a resource hierarchy;

wherein the resource is a portal, a portlet or a page, the resource inheriting a role from another resource higher in the resource hierarchy;

evaluate a policy based on the at least one role; and

determine whether to grant access to the resource based on the evaluation of the policy;

wherein roles are inherited by resources lower in the resource hierarchy unless the resources lower in the resource hierarchy are associated with roles of the same name, in which case, the role inheritance is overridden.

2. The computer readable medium of claim 1 further comprising instructions which when executed cause the system to:

allow the principal to be an authenticated user, group or process.

3. The computer readable medium of claim 1 wherein:

mapping includes determining whether or not the at least one role is satisfied by the principal.

4. The computer readable medium of claim 1 further comprising instructions which when executed cause the system to:

evaluate the at least one role to true or false for the principal in a context.

5. The computer readable medium of claim 1 wherein:

the at least one role is a Boolean expression that can include at least one of another Boolean expression and a predicate.

6. The computer readable medium of claim 5 wherein:

the predicate is evaluated against the principal and a context.

7. The computer readable medium of claim 5 wherein:

the predicate is one of user, group, time and segment.

8. The computer readable medium of claim 7 wherein:

the segment predicate is specified in plain language.

9. The computer readable medium of claim 1 wherein:

the policy is an association between the resource and a set of roles.

10. The computer readable medium of claim 9 further comprising instructions which when executed cause the system to:

grant access to the resource if the at least one role is in the set of roles.

11. A computer readable medium have sets of instructions stored thereon which, when executed by a machine, cause the machine to:

evaluate a policy based on at least one role applicable to a principal attempting to access the resource, the resource being part of a resource hierarchy;

wherein the resource is a portal, a portlet or a page, the resource inheriting a role from another resource higher in the resource hierarchy;

grant access to the resource based on the evaluation; and

wherein the resource, the policy and the at least one role are hierarchically related;

wherein roles are inherited by resources lower in the resource hierarchy unless the resources lower in the resource hierarchy are associated with roles of the same name, in which case, the role inheritance is overridden.

12. The computer readable medium of claim 11, wherein the sets of instructions when further executed by the machine, cause the machine to allow the principal to be an authenticated user, group or process.

13. The computer readable medium of claim 11, wherein the at least one role is applicable to a principal if the at least one role is satisfied by the principal.

14. The computer readable medium of claim 11 , wherein the sets of instructions when further executed by the machine, cause the machine to evaluate the at least one role to true or false for the principal in a context.

15. The computer readable medium of claim 11, wherein the at least one role is a Boolean expression that includes at least one of (1) another Boolean expression and (2) a predicate.

16. The computer readable medium of claim 15 , wherein the sets of instructions when further executed by the machine, cause the machine to evaluate the predicate against the principal and a context.

17. The computer readable medium of claim 15, wherein the predicate is one of user, group, time and segment.

18. The computer readable medium of claim 17, wherein the segment predicate is specified in plain language.

19. The computer readable medium of claim 11, wherein the policy is an association between the resource and a set of roles.

20. The computer readable medium of claim 19, wherein the sets of instructions when further executed by the machine, cause the machine to grant access to the resource if the at least one role is in the set of roles.
