Information
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.
Rationale:
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.
Impact:
Disabling CUPS will prevent printing from the system, a common task for workstation systems.
Solution
Run the following command to disable cups:
# systemctl --now disable cups
