F5BI-LT-000075 - The BIG-IP Core implementation must be configured with a pre-established trust relationship and mechanisms with appropriate authorities (e.g., Active Directory or authentication, authorization, and accounting (AAA) server) that validate user account access authorizations and privileges when providing access control to virtual servers.

Information

User account and privilege validation must be centralized in order to prevent unauthorized access using changed or revoked privileges.

ALGs can implement functions such as traffic filtering, authentication, access, and authorization functions based on computer and user privileges. However, the directory service (e.g., Active Directory or LDAP) must not be installed on the ALG, particularly if the gateway resides on the untrusted zone of the Enclave.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

If user access control intermediary services are provided, configure the BIG-IP Core as follows:

Configure a policy in the BIG-IP APM module with a pre-established trust relationship and mechanisms with appropriate authorities that validate each user access authorization and privileges.

Apply the APM policy to the applicable Virtual Server(s) in the BIG-IP LTM module to validate user account access authorizations and privileges when providing access control to virtual servers.
