Technical

>Control Description

(A) The information system prevents further access to the system by initiating a session lock after ⚙organization-defined time period of inactivity or upon receiving a request from a user. (B) The information system retains the session lock until the user re-establishes access using established identification and authentication procedures.

>Supplemental Guidance

Session locks are temporary actions taken when users stop work and move away from the immediate vicinity of information systems but do not want to log out because of the temporary nature of their absences. Session locks are implemented where session activities can be determined. This is typically at the operating system level, but can also be at the application level.

Session locks are not an acceptable substitute for logging out of information systems, for example, if organizations require users to log out at the end of workdays. Related control: AC-7
