Puppet Class: cis_security_hardening::rules::cups

Defined in:
manifests/rules/cups.pp

Summary

Ensure CUPS is not enabled

Overview

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.

Examples:

class { 'cis_security_hardening::rules::cups':
    enforce => true,
}

Parameters:

  • enforce (Boolean) (defaults to: false) —

    Enforce the rule
