Information
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 DoD Interoperability Root CA cross-certificates must be installed in the Untrusted Certificate Store. This requirement only applies to unclassified systems.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
Install the DoD Interoperability Root CA cross-certificates on unclassified systems.

Administrators should run the Federal Bridge Certification Authority (FBCA) Cross-Certificate Removal Tool once as an administrator and once as the current user.
The FBCA Cross-Certificate Remover tool and user guide is available on IASE at http-//iase.disa.mil/pki-pke/Pages/tools.aspx.
