Description
A session lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system, but does not want to log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. Rather than be forced to wait for a period of time to expire before the user session can be locked, network elements need to provide users with the ability to manually invoke a session lock so users may secure their session should the need arise for them to temporarily vacate the immediate physical vicinity. This policy only applies to gateways (e.g., identity management or authentication gateways) that provide user account services as part of the intermediary services.
