Fix Recommendation

If user authentication intermediary services are provided, configure the BIG-IP Core to use a specific authentication server(s) as follows:

Configure a policy in the BIG-IP APM module to use authentication for network access to non-privileged accounts.

Apply the APM policy to the applicable Virtual Server(s) in BIG-IP LTM module to restrict user authentication traffic to specific authentication server(s) when providing access control to virtual servers.

Check Contents

If the BIG-IP Core does not provide user authentication intermediary services for virtual servers, this is not applicable.

When user authentication intermediary services are provided, verify the BIG-IP Core is configured as follows:

Verify Virtual Server(s) in the BIG-IP LTM module are configured with an APM policy to use a specific authentication server(s).

Navigate to the BIG-IP System manager >> Local Traffic >> Virtual Servers >> Virtual Servers List tab.

Select Virtual Servers(s) from the list to verify.

Verify under "Access Policy" section that "Access Policy" has been set to use an APM access policy that has been configured with a pre-established trust relationship and mechanisms with appropriate authorities that validate each user access authorization and privileges.

If the BIG-IP Core provides user authentication intermediary services and does not restrict user authentication traffic to a specific authentication server(s), this is a finding.
