Puppet Class: security_baseline::rules::common::sec_dhcpd

Defined in:
manifests/rules/common/sec_dhcpd.pp

Summary

Ensure DHCP Server is not enabled (Scored)

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 security_baseline::rules::common::sec_dhcpd {
    enforce => true,
    message => 'Test',
    log_level => 'info'
}

Parameters:

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

    Enforce the rule or just test and log

  • message (String) (defaults to: '') —

    Message to print into the log

  • log_level (String) (defaults to: '') —

    The log_level for the above message
