Puppet Class: cis_security_hardening::rules::rsh_server

Defined in:
manifests/rules/rsh_server.pp

Summary

Ensure rsh-server is not installed

Overview

The operating system must not have the rsh-server package installed.

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.

Operating systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions).

Examples of non-essential capabilities include, but are not limited to, games, software packages, tools, and demonstration software, not related to requirements or providing a wide array of functionality not required for every mission, but which cannot be disabled.

Examples:

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

Parameters:

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

    Enforce the rule
