Verify the AOS configuration with the following command:

1. Site-to-site VPN:
Using the CLI:
show crypto isakmp sa

If the IPsec security association is not operating with certificates ("-c"), this is a finding.

2. Hardware client VPN:
Using the web GUI, navigate to Configuration >> Access Points >> Remote APs. Review each provisioned Remote Access Point (RAP) and verify that each AP has "c" in the FLAGS column.

If certificate authentication is not configured for each RAP, this is a finding.
