Puppet Class: cis_security_hardening::rules::disable_atm

Defined in:
manifests/rules/disable_atm.pp

Summary

Ensure ATM is disabled

Overview

The operating system must disable the asynchronous transfer mode (ATM) protocol.

Rationale: It is detrimental for operating systems to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors.

Failing to disconnect unused protocols can result in a system compromise.

The Asynchronous Transfer Mode (ATM) is a protocol operating on network, data link, and physical layers, based on virtual circuits and virtual paths. Disabling ATM protects the system against exploitation of any laws in its implementation.

Examples:

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

Parameters:

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

    Enforce the rule.
