What is a policy enforcement point?

The Policy Enforcement Point (PEP) is the piece of network or security equipment that controls user access and ensures the authorization decision made by the Policy Decision Point (PDP). In some NAC implementations, the PDP is a wired switch or wireless access point.

What is PBAC and ABAC?

Policy Based Access Control (PBAC) also known as Attribute Based Access Control (ABAC) uses attributes to dynamically enforce access controls according to business policies.

What is RBAC and PBAC?

What is XACML in Oasis?

What is the XACML profile for role based access control (RBAC)?

This specification defines a profile for the use of XACML in expressing policies that use role based access control (RBAC). It extends the XACML Profile for RBAC Version 1.0 to include a recommended Attribute field for roles, but reduces the scope to address only “core” and “hierarchical” RBAC.

What is an authorization decision in XACML?

  Any proprietary system using the XACML specification MUST transform an XACML context element into the form of its authorization decision.
