Download free ISO 27001 Access Control Security Mechanism Checklists. This Access Control Checklist covers:

• Access control lists (ACLs). ACLs are posted centrally and implement access by representing the columns as lists of users attached to the protected objects. The speed of ACL searches can be increased by the use of user groups and wildcards. Also, groups make the management of ACLs easier. Access to the ACLs need to be controlled as tightly as the objects themselves or they can be manipulated.

• Capabilities. This involves the assignment of a required capability set to an object (file, directory, process, and so forth) such that only those subjects (users or processes) who possess all of the required capabilities are permitted to access the object. Essentially, users (subjects) are assigned capabilities (sets). The objects have lists of required capabilities that users must have in order to access them. This noncentralized approach makes tracking and administering permissions difficult, particularly in revocations, since it is difficult to know who has access to what objects and they can still pass access on to others.

• Profiles. Profiles are posted with users and implement user access to an object only if it falls within the user’s profile. However, since object names are not consistent or amenable to grouping, they cannot be reduced. Also, if a user has access to many protected objects, his or her profile can get long. Another problem is change. That is, if an object’s path/location changes, all user profiles accessing it must somehow be located and changed. Again, the lack of a centralized permissions list makes tracking and administering difficult.
