F5BI-AP-000077 - The BIG-IP APM module must restrict user authentication traffic to specific authentication server(s) when providing user authentication to virtual servers - s when providing user auth to virtual servers.
User authentication can be used as part of the policy filtering rule sets. Some URLs or network resources can be restricted to authenticated users only. Users are prompted by the application or browser for credentials. Authentication service may be provided by the ALG as an intermediary for the application; however, the authentication credential must be stored in the site's directory services server. This requirement only applies to components where this is specific to the function of the device or has the concept of an organizational user (e.g., proxy capability). This does not apply to authentication for the purpose of configuring the device itself (i.e., device management). NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
If user authentication intermediary services are provided, configure an access policy in the BIG-IP APM module to restrict user authentication traffic to specific authentication server(s).
