Assessment Procedure

Check Text

If DOD is not at C2C Step 4 or higher, this is not a finding.

Verify the posture policy will verify that anti-malware software is installed and up to date.

If not required by the NAC SSP, this is not a finding.

1. Navigate to Work Center >> Posture >> Posture Policy.
2. Check the enabled posture policies analyzing all the conditions.
3. Review the requirements listed on polices the posture required clients will use.
4. Navigate to Work Center >> Posture >> Policy Elements.
5. Review the requirements applied in the posture policy to verify anti-malware conditions have been applied.
6. Review the anti-malware conditions, to determine if one is configured to verify that the software is installed, and one is configured to verify the software is up to date. 

If this requirement is met by another system or application, this is not applicable. 

If there is not a firewall condition tied to a requirement applied to an applicable posture policy, this is a finding.
