Forescout must deny or restrict access for endpoints that fail critical endpoint security checks. This is required for compliance with C2C Step 4.

Rule version FORE-NC-000140 · STIG v2 · 2026-09-01

Discussion

Devices that do not meet minimum-security configuration requirements pose a risk to the DoW network and information assets.

Endpoint devices must be disconnected or given limited access as designated by the approval authority and system owner if the device fails the authentication or security assessment. The user will be presented with a limited portal, which does not include access options for sensitive resources. Required security checks must implement DoW policy requirements.

Check

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

Verify Forescout has been configured to redirect non-compliant devices to a limited access network to include a remediation network or apply an ACL limited access network.

If a policy does not exist that redirects the failed device to an authorized network for remediation or limited access or the NAC does not deny or restrict access for endpoints that fail critical endpoint security checks, this is not a finding.

Fix

Use the Forescout Administrator UI to configure any pre-connect policies to ensure endpoints that fail the baseline security configuration requirements are set to either restrict access or isolate the endpoint.

1. Log on to the Forescout UI. 2. From the Policy tab, check any Pre-Connect policies to ensure devices that fail the baseline security configuration requirements are set to either restrict access to production network, are granted access to only remediation network, or are granted to a limited access network.
