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.

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.

Who does this work

7 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-242600r812782_chk)

If DoD is not at C2C Step 4 or higher, this is not a finding. Verify that the 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. If the default authorization policy within each policy set has "deny-access" or restricted access, this is not a finding.

Fix Text (F-45832r714109_fix)

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.
