AC.L2-3.1.11 — Session Termination

This requirement addresses the termination of user-initiated logical sessions in contrast to the termination of network connections that are associated with communications sessions (i.e., disconnecting from the network) in [](#/cprt/framework/version/SP_800_171_3_0_0/home?element=03.13.09)03.13.09. A logical session is initiated whenever a user (or processes acting on behalf of a user) accesses a system. Logical sessions can be terminated (and thus terminate user access) without terminating network sessions. Session termination ends all system processes associated with a user’s logical session except those processes that are created by the user (i.e., session owner) to continue after the session is terminated. Conditions or trigger events that require automatic session termination can include organization-defined periods of user inactivity, time-of-day restrictions on system use, and targeted responses to certain types of incidents.
