The BIG-IP Core implementation providing user authentication intermediary services must restrict user authentication traffic to specific authentication server(s) when providing access control to virtual servers.
An XCCDF Rule
Description
<VulnDiscussion>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).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
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.
