AS24-W1-000800 - The Apache web server must only accept client certificates issued by DoD PKI or DoD-approved PKI Certification Authorities (CAs).
Non-DoD-approved PKIs have not been evaluated to ensure they have security controls and identity vetting procedures in place that are sufficient for DoD systems to rely on the identity asserted in the certificate. PKIs lacking sufficient security controls and identity vetting procedures risk being compromised and issuing certificates that enable adversaries to impersonate legitimate users. NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Configure the web server's trust store to trust only DoD-approved PKIs (e.g., DoD PKI, DoD ECA, and DoD-approved external partners).
