It is used as an add-on to various types of access provisioning systems (Role-Based, Mandatory, and Discretionary) and can further change or modify the access permission to the particular set of rules as and when required. Symmetric RBAC supports permission-role review as well as user-role review. With router ACLs we determine which IPs or port numbers are allowed through the router, and this is done using rules.
