Forescout must enforce the revocation of endpoint access authorizations at the next compliance assessment interval based on changes to the compliance assessment security policy. This is required for compliance with C2C Step 4.

Description
This requirement gives the option to configure for automated remediation and/or manual remediation. A detailed record must be passed to the remediation server for action. Alternatively, the details can be passed in a notice to the user for action. The device status will be updated on the network access server/authentication server so that further access attempts are denied. The NAC must have policy assessment mechanisms with granular control to distinguish between access restrictions based on the criticality of the software or setting failure.

Who does this work

17 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-233321r1001247_chk)

If DOD is not at C2C Step 4 or higher, this is not a finding. 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-36481r803464_fix)

Use the Forescout Administrator UI to configure the authorization policy to configured to perform a control action on any devices that have not met authorization requirement or are no longer authorized. 1. Log on to the Forescout UI. 2. 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.
