Puppet Class: security_baseline::rules::common::sec_dns

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

Summary

Ensure DNS Server is not enabled (Scored)

Overview

The Domain Name System (DNS) is a hierarchical naming system that maps names to IP addresses for computers, services and other resources connected to a network.

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

Examples:

class security_baseline::rules::common::sec_dns {
    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
