Remote connections must be disconnected and verified as disconnected when nonlocal maintenance sessions have been terminated and are no longer available for use.
Verify the operating system verifies remote disconnection at the termination of nonlocal maintenance and diagnostic sessions, when used for nonlocal maintenance sessions. If it does not, this is a finding.
