IIST-SI-000241 - The IIS 10.0 website must only accept client certificates issued by DoD PKI or DoD-approved PKI Certification Authorities (CAs).

Information

The use of a DoD PKI certificate ensures clients the private website they are connecting to is legitimate, and is an essential part of the DoD defense-in-depth strategy.
