Check Text ( C-36515r605663_chk )
Verify Forescout admission policy has been configured to revoke access to endpoints that have not met or are removed from the authorized group. If Forescout is not configured with an admissions policy that enforces the revocation of endpoint access authorizations based on when devices are removed from an authorization group, this is a finding.

Fix Text (F-36480r605664_fix)
Log on to the Forescout UI. From the Policy tab, check that the authorization policy has a Block Action enabled on any devices that have not met or are removed from the authorized group.
