Puppet Class: cis_security_hardening::rules::shadow_perms

Defined in:
manifests/rules/shadow_perms.pp

Summary

Ensure permissions on /etc/shadow are configured

Overview

The /etc/shadow file is used to store the information about user accounts that is critical to the security of those accounts, such as the hashed password and other security information.

Rationale: If attackers can gain read access to the /etc/shadow file, they can easily run a password cracking program against the hashed password to break it. Other security information that is stored in the /etc/shadow file (such as expiration) could also be useful to subvert the user accounts.

Examples:

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

Parameters:

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

    Enforce the rule
