Description
DOD root and intermediate PKI certificates are used to verify the authenticity of PKI certificates of users and web services. If the root and intermediate certificates are not available, an adversary could falsely sign a certificate in such a way that it could not be detected. Providing access to the DOD root and intermediate PKI certificates greatly diminishes the risk of this attack. SFR ID: FMT_MOF_EXT.1.2 #47
