Description
To ensure users do not experience denial of service when performing certificate-based authentication to DOD websites due to the system chaining to a root other than DOD Root CAs, the US DOD CCEB Interoperability Root CA cross-certificates must be installed in the Untrusted Certificate Store. This requirement only applies to unclassified systems. Satisfies: SRG-OS-000066-GPOS-00034, SRG-OS-000403-GPOS-00182
