Explanation
RADIUS Change of Authorization (CoA) is used in network access control (NAC) implementations to dynamically change the authorization attributes of an authenticated session. It allows administrators to push new policies or enforce updated access controls without requiring the user to reauthenticate or disconnect. Typical use cases for RADIUS CoA include: - Updating the user's access control list (ACL) based on post-authentication checks. - Assigning VLANs dynamically based on policy changes. - Enforcing new quality of service (QoS) settings.
