F5BI-LT-000085 - The BIG-IP Core implementation providing PKI-based, user authentication intermediary services must be configured to map the authenticated identity to the user account for PKI-based authentication to virtual servers.
Information
Authorization for access to any network element requires an approved and assigned individual account identifier. To ensure only the assigned individual is using the account, the account must be bound to a user certificate when PKI-based authentication is implemented. This requirement applies to ALGs that provide user authentication intermediary services (e.g., authentication gateway or TLS gateway). This does not apply to authentication for the purpose of configuring the device itself (device management). NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
If PKI-based, user authentication intermediary services are provided, configure the BIG-IP Core as follows: Configure a policy in the BIG-IP APM module to map the authenticated identity to the user account for PKI-based authentication. Apply APM policy to the applicable Virtual Server(s) in BIG-IP LTM module to map the authenticated identity to the user account for PKI-based authentication to virtual servers.
