Puppet Class: cis_security_hardening::rules::krb5_server

Defined in:
manifests/rules/krb5_server.pp

Summary

Ensure the krb5-server package has not been installed on the system

Overview

The krb5-server package must not be installed. Rationale: Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be relied upon to provide confidentiality or integrity, and DoD data may be compromised.

RHEL 8 operating systems utilizing encryption are required to use FIPS-compliant mechanisms for authenticating to cryptographic modules.

Currently, Kerberos does not utilize FIPS 140-2 cryptography.

FIPS 140-2 is the current standard for validating that mechanisms used to access cryptographic modules utilize authentication that meets DoD requirements. This allows for Security Levels 1, 2, 3, or 4 for use on a general-purpose computing system.

Examples:

class { 'cis_security_hardening::rules::krb5_server':
  enforce => true,
}

Parameters:

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

    Enforce the rule.
