The Cisco ISE must deny network connection for endpoints that cannot be authenticated using an approved method. This is required for compliance with C2C Step 4.
An XCCDF Rule
Description
Without identifying devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Identification failure does not need to result in connection termination or preclude compliance assessment. This is particularly true for unmanaged systems or when the Cisco ISE is performing network discovery.

A Manual Procedure
Configure each policy set so that authorization policies have either "deny-access" or restricted access on their default authorization policy set.
1. Work Centers >> Network Access >> Policy Sets.
2. Choose ">" on the desired policy set.
3. Expand Authorization Policy.
On the default authorization rule, select "Deny-Access" or a result that is configured for a restricted VLAN, ACL, SGT, or any combination of these used to restrict the access.
