Note: This requirement is not applicable if the router or switch does not have any public key certificates. Review the switch configuration to determine if a CA trust point has been configured. The CA trust point will contain the URL of the CA in which the switch has enrolled with. Verify this is a DOD or DOD-approved CA. This will ensure the switch has enrolled and received a certificate from a trusted CA. The CA trust point configuration would look similar to the example below: crypto pki trustpoint CA_X enrollment url http://trustpoint1.example.com Note: A remote end-point's certificate will always be validated by the switch by verifying the signature of the CA on the certificate using the CA's public key, which is contained in the switch's certificate it received at enrollment. If the Cisco switch is not configured to obtain its public key certificates from an appropriate certificate policy through an approved service provider, this is a finding.
