SLEM 5 must initiate a session lock after a 15-minute period of inactivity. (Cat II impact)

Discussion

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. Rather than relying on the users to manually lock their SLEM 5 session prior to vacating the vicinity, SLEM 5 needs to be able to identify when a user's session has idled and take action to initiate the session lock. The session lock is implemented at the point where session activity can be determined and/or controlled.

Check Content

Verify SLEM 5 must initiate a session logout after a 15-minute period of inactivity for all connection type with the following command: > cat /etc/profile.d/autologout.sh TMOUT=900 readonly TMOUT export TMOUT If the file "/etc/profile.d/autologout.sh" does not exist or the output from the function call is not exactly the same, this is a finding.

Fix Text

Configure SLEM 5 to initiate a session lock after a 15-minute period of inactivity. Create or edit the "/etc/profile.d/autologout.sh" file and add or modify the following lines: TMOUT=900 readonly TMOUT export TMOUT Set the proper permissions for the "/etc/profile.d/autologout.sh" file with the following command: > sudo chmod +x /etc/profile.d/autologout.sh
