The Common Unix Print System (CUPS) provides the ability to print to both local and network printers. A system running CUPS can also accept print jobs from remote systems and print them to local printers. It also provides a web based remote administration capability.
If the system does not need to print jobs or accept print jobs from other systems, it is recommended that CUPS be disabled to reduce the potential attack surface.
Run the following command to verify cups is not installed:
# dpkg-query -W -f='${binary:Package}\t${Status}\t${db:Status-Status}\n' cups
If installed, run:
# systemctl is-enabled cups.socket cups.service
# systemctl is-active cups.socket cups.service
Verify the services are not enabled and not active.
cups should not be installed, or if installed, the services should be stopped and masked.
Run the following commands to stop, mask, and purge cups:
# systemctl stop cups.socket cups.service
# systemctl mask cups.socket cups.service
# apt purge cups
cups is installed by default on desktop installations.
