STIGQter: STIG Summary: Forescout Network Access Control Security Technical Implementation Guide Version: 2 Release: 5 Benchmark Date: 01 Jul 2026:

For endpoints that require automated remediation, Forescout must be configured to logically separate endpoints from the trusted network traffic during remediation. This is required for compliance with C2C Step 4.

Fix Recommendation

Use the Forescout Administrator UI to configure a policy, per the SSP, that isolates endpoints requiring automated remediation from other endpoints on the trusted network. The following is an example only.

1. From the Policy tab, select the top most policy.
2. Select Add >> Classification >> Primary Classification, and then click Next.
3. Give the policy a name, then click Next.
4. Select the IP Address Range the policy will apply to, click "OK," and then click "Next".
5. Select "Finish", and then click "Apply".

This collects a series of attributes for each endpoint that can then be used in a policy as the unique identifier. However, by default the IP address is used, for example in the log records.

Check Contents

If DOD is not at C2C Step 4 or higher, this is not a finding.
If a separate remediation network is configured and isolated from the trusted network, this is not a finding.

Use the Forescout Administrator UI to verify that Forescout is configured to either redirect endpoints requiring automated remediation to a network segment that is isolated from trusted traffic or, if assessment is done on the Forescout, the endpoint traffic is logically separate during remediation.

If Forescout does not isolate endpoints during remediation, this is a finding.
