Description
A DoD private web site must utilize PKI as an authentication mechanism for web users. Information systems residing behind web servers requiring authorization based on individual identity shall use the identity provided by certificate-based authentication to support access control decisions. Not using client certificates allows an attacker unauthenticated access to private web sites.
