| 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. | ||||

Details
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
