If AAA Services are not used for 802.1x authentication or to authenticate privileged users for device management, this is not applicable. Verify AAA Services are configured to use a unique shared secret with clients requesting authentication services. The shared secret is to be the same for communication between AAA Services and the client devices. All shared secrets must meet password complexity requirements. If AAA Services are not configured to use a unique shared secret for communication with clients requesting authentication services, this is a finding.

Fix Text (F-87795r1_fix)
Configure AAA Services to use a unique shared secret for communication (i.e. RADIUS, TACACS+) with all clients requesting authentication services.
