Puppet Class: cis_security_hardening::rules::sshd_install

Defined in:
manifests/rules/sshd_install.pp

Summary

Ensure SSH is installed and active

Overview

The operating system must use SSH to protect the confidentiality and integrity of transmitted information.

Rationale: Without protection of the transmitted information, confidentiality and integrity may be compromised because unprotected communications can be intercepted and either read or altered.

This requirement applies to both internal and external networks and all types of information system components from which information can be transmitted (e.g., servers, mobile devices, notebook computers, printers, copiers, scanners, and facsimile machines). Communication paths outside the physical protection of a controlled boundary are exposed to the possibility of interception and modification.

Protecting the confidentiality and integrity of organizational information can be accomplished by physical means (e.g., employing physical distribution systems) or by logical means (e.g., employing cryptographic techniques). If physical means of protection are employed, then logical means (cryptography) do not have to be employed, and vice versa.

Satisfies: SRG-OS-000423-GPOS-00187, SRG-OS-000425-GPOS-00189, SRG-OS-000426- GPOS-00190

Examples:

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

Parameters:

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

    Enforce the rule.
