Title

RHEL 10 must automatically exit interactive command shell user sessions after 10 minutes of inactivity.

Control

Verify RHEL 10 is configured to exit interactive command shell user sessions after 10 minutes of inactivity or less with the following command: $ sudo grep -i tmout /etc/profile /etc/profile.d/*.sh /etc/profile.d/tmout.sh:declare -xr TMOUT=600 If "TMOUT" is not set to "600" or less in a script located in the "/etc/'profile.d/" directory, is missing, or is commented out, this is a finding.

Discussion

Terminating an idle interactive command shell user session within a short time period reduces the window of opportunity for unauthorized personnel to take control of it when left unattended in a virtual terminal or physical console. Satisfies: SRG-OS-000163-GPOS-00072, SRG-OS-000029-GPOS-00010

Fix
