Puppet Class: cis_security_hardening::rules::shells_perms

Defined in:
manifests/rules/shells_perms.pp

Summary

Ensure permissions on /etc/shells are configured

Overview

/etc/shells is a text file which contains the full pathnames of valid login shells. This file is consulted by chsh and available to be queried by other programs.

Rationale: It is critical to ensure that the /etc/shells file is protected from unauthorized access. Although it is protected by default, the file permissions could be changed either inadvertently or through malicious actions.

Examples:

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

Parameters:

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

    Enforce the rule
