Puppet Class: cis_security_hardening::rules::dhcp

Defined in:
manifests/rules/dhcp.pp

Summary

Ensure DHCP Server is not enabled

Overview

The Dynamic Host Configuration Protocol (DHCP) is a service that allows machines to be dynamically assigned IP addresses.

Rationale: Unless a system is specifically set up to act as a DHCP server, it is recommended that this service be disabled to reduce the potential attack surface.

Examples:

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

Parameters:

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

    Enforce the rule
