Description
All systems are vulnerable if terminals are left logged in and unattended. Leaving system terminals unsecure poses a potential security hazard. If the interface is AIXwindows (CDE), use the xlock command to lock the sessions.

Check Text (C-215188r958400_chk)

If AIX CDE (X11) is not used, this is Not Applicable. Check the system to determine if "X11.apps.clients" is installed: # lslpp -L X11.apps.clients If the "X11.apps.clients" fileset is not installed, this is a finding. Check if "xlock" command exists using the following command: # ls /usr/bin/X11/xlock The above command should display the following: /usr/bin/X11/xlock If the above command does not show that "/usr/bin/X11/xlock" exists, this is a finding.

Fix Text (F-16384r294016_fix)

Install "X11.apps.clients" fileset from the AIX DVD Volume 1 using the following command (assuming that the DVD is mounted to/dev/cd0): # installp -aXYgd /dev/cd0 -e /tmp/install.log X11.apps.clients
