RHEL 9 Goss config

Overview

based on RedHat 8 CIS 2.0.0

Set of configuration files and directories to run the first stages of CIS of RHEL 9 servers

This is configured in a directory structure level.

Goss is run based on the goss.yml file in the top level directory. This specifies the configuration.

Requirements

You must have goss available to your host you would like to test.

You must have sudo/root access to the system as some commands require privilege information.

Assuming you have already clone this repository you can run goss from where you wish.

Please refer to the audit documentation for usage.

• Audit Documents

This also works alongside the Ansible Lockdown RHEL9-CIS role

Which will:

• install
• audit
• remediate
• audit

variables

file: vars/CIS.yml

Please refer to the file for all options and their meanings

CIS listed variable for every control/benchmark can be turned on/off or section

• other controls enable_selinux run_heavy_tasks

• bespoke options If a site has specific options e.g. password complexity these can also be set.

Usage

You must have goss available to your host you would like to test.

You must have root access to the system as some commands require privilege information.

• Run as root not sudo due to sudo and shared memory access

Assuming you have already clone this repository you can run goss from where you wish.

• full check
