Description
A session time-out 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 log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. This is typically at the operating system-level, but may also be at the application level. The organization must define the period of inactivity before a session lock is initiated, so this setting must be configurable. In SharePoint, enabling security validation provides application level security for web pages while the authenticated user is absent. The user must be required to re-authenticate after a specified inactivity period is exceeded.
