→Rule Based Access Control
Rule Based Access Control (RBAC) introduces acronym ambiguity by using the same four letter abbreviation (RBAC) as Role Based Access Control.
Under Rules Based Access Control, access is allowed or denied to resource objects based on a set of rules defined by a system administrator. As with ''Discretionary Access Control'', access properties are stored in Access Control Lists (ACL) associated with each resource object. When a particular account or group attempts to access a resource, the operating system checks the rules contained in the ACL for that object .
Examples of Rules Based Access Control include situations such as permitting access for an account or group to a network connection at certain hours of the day or days of the week.
