The Photon operating system must be configured so that the x86 Ctrl-Alt-Delete key sequence is disabled on the command line.

| Description |
|---|
| 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. |
