Title

The Cisco ISE must verify host-based IDS/IPS software is authorized and running on posture required clients defined in the NAC System Security Plan (SSP) prior to granting trusted network access. This is required for compliance with C2C Step 4. (Cat I impact)

Discussion

Automated policy assessments must reflect the organization's current security policy so entry control decisions will happen only where remote endpoints meet the organization's security requirements. If the remote endpoints are allowed to connect to the organization's network without passing minimum-security controls, they become a threat to the entire network.

Check Content

If DoD is not at C2C Step 4 or higher, this is not a finding. If not required by the NAC SSP, this is not a finding. Verify that the posture policy will verify that a host-based IPS is running. 1. Navigate to Work Center >> Posture >> Posture Policy. 2. Look over the enabled posture policies analyzing all the conditions. 3. Review the requirements listed on polices that the posture required clients will use. 4. Navigate to Work Centers >> Posture >> Policy Elements. 5. Review the requirements applied in the posture policy to ensure there is one with a firewall condition applied. 6. Review the firewall condition ensuring it is configured to verify that the client firewall is enabled. If there is not a firewall condition tied to a requirement that is applied to an applicable posture policy, this is a finding.
