| Description | ||||
| If the remote connection is not closed and verified as closed, the session may remain open and be exploited by an attacker; this is referred to as a zombie session. Remote connections must be disconnected and verified as disconnected when nonlocal maintenance sessions have been terminated and are no longer available for use. | ||||
