Title

IBM z/OS must employ a session manager to manage retaining a users session lock until that user reestablishes access using established identification and authentication procedures.

Check Content

Verify the any Session Manager in use retains a user's session lock until that user reestablishes access using established identification and authentication procedures. If it does not, this is a finding.

Discussion

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. Regardless of where the session lock is determined and implemented, once invoked, the session lock will remain in place until the user re-authenticates. No other activity aside from re-authentication will unlock the system.

Fix

Configure any Session Manager in use to retain a user's session lock until that user reestablishes access using established identification and authentication procedures.
