Check: PHTN-67-000095
VMware vSphere 6.7 Photon OS STIG:
PHTN-67-000095
(in versions v1 r6 through v1 r1)
Title
The Photon operating system must be configured so that the x86 Ctrl-Alt-Delete key sequence is disabled on the command line. (Cat II impact)
Discussion
When the Ctrl-Alt-Del target is enabled, a locally logged-on user who presses Ctrl-Alt-Delete, when at the console, can reboot the system. If accidentally pressed, as could happen in the case of a mixed OS environment, this can create the risk of short-term loss of systems availability due to unintentional reboot.
Check Content
At the command line, execute the following command: # systemctl status ctrl-alt-del.target Expected result: ctrl-alt-del.target Loaded: masked (/dev/null; bad) Active: inactive (dead) If the output does not match the expected result, this is a finding.
Fix Text
At the command line, execute the following command: # systemctl mask ctrl-alt-del.target
