6.3 Ensure print server is not enabled (Not Scored)

Profile Applicability

• Level 1

Description

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.

Audit Procedure

Using Command Line

Ensure no start conditions listed for cups:

initctl show-config cups cups

Expected Result

No start conditions should be listed for cups.

Remediation

Using Command Line

Remove or comment out start lines in /etc/init/cups.conf:

sed -i 's/^start/#start/' /etc/init/cups.conf

Default Value

Enabled by default on Ubuntu 12.04 LTS Server.
