Fix Recommendation

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.

Check Contents

If a policy does not exist that redirects the failed device to an authorized network for remediation or limited access, this is not a finding.

If the NAC does not deny or restrict access for endpoints that fail critical endpoint security checks, this is a finding.
