The F5 BIG-IP appliance must be configured to use a Diffie-Hellman (DH) Group of 16 or greater for Internet Key Exchange (IKE) Phase 1.

Description
NIST cryptographic algorithms approved by NSA to protect NSS. Based on an analysis of the impact of quantum computing, cryptographic algorithms specified by CNSSP-15 and approved for use in products in the CSfC program, the approved algorithms have been changed to more stringent protocols configure with increased bit sizes and other secure characteristics to protect against quantum computing threats. The Commercial National Security Algorithm Suite (CNSA Suite) replaces Suite B.

From the BIG-IP GUI: 1. Network. 2. IPsec. 3. IKE Peers. 4. Click on the IKE Peer Name. 5. In "IKE Phase 1 Algorithms", verify "MODP4096" or higher is selected for "Perfect Forward Secrecy". If the BIG-IP appliance is not configured to use a Diffie-Hellman (DH) Group of 16 or greater for Internet Key Exchange (IKE) Phase 1, this is a finding.
