This repository is a work in progress. It is not yet ready for use on Debian 11.
This repository is a fork of ansible-lockdown/UBUNTU22-CIS since ansible-lockdown/DEBIAN11-CIS has not been publically released yet but there is significant overlap between the CIS Benchmark for Ubuntu 22 and Debian 11.
Configure a Ubuntu 22 machine to be CIS compliant
Based on CIS Ubuntu Linux 22.04 LTS Benchmark v1.0.0 Release

This role will make changes to the system that could break things. This is not an auditing tool but rather a remediation tool to be used after an audit has been conducted.
This role was developed against a clean install of the Operating System. If you are implementing on an existing system, please review this role for any site-specific changes that are needed.

- Getting the Most Out of the Role
General:
- Basic knowledge of Ansible, below are some links to the Ansible documentation to help get started if you are unfamiliar with Ansible
- Functioning Ansible and/or Tower Installed, configured, and running. This includes all of the base Ansible/Tower configurations, needed packages installed, and infrastructure setup.
- Please read through the tasks in this role to gain an understanding of what each control is doing. Some of the tasks are disruptive and can have unintended consequences in a live production system. Also, familiarize yourself with the variables in the defaults/main.yml file or the Main Variables Wiki Page.
Technical Dependencies:
- Running Ansible/Tower setup (this role is tested against Ansible version 2.10.1 and newer)
- Python3 Ansible run environment
- goss >= 0.4.0 (If using for audit)
This can be turned on or off within the defaults/main.yml file with the variable run_audit. The value is false by default, please refer to the wiki for more details.
This is a much quicker, very lightweight, checking (where possible) config compliance and live/running settings.
A new form of auditing has been developed, by using a small (12MB) go binary called goss along with the relevant configurations to check. Without the need for infrastructure or other tooling. This audit will not only check the config has the correct setting but aims to capture if it is running with that configuration also trying to remove false positives in the process.
Refer to UBUNTU22-CIS-Audit.

This role is designed so the end user should not have to edit the tasks themselves. All customizing should be done via the defaults/main.yml file or with extra vars within the project, job, workflow, etc.
- devel - This is the default branch and the working development branch. Community pull requests will be pulled into this branch
- main - This is the release branch
- reports - This is a protected branch for our scoring reports, no code should ever go here
- gh-pages - This is the GitHub pages branch
- all other branches - Individual community member branches
We encourage you (the community) to contribute to this role. Please read the rules below.
- Your work is done in your own individual branch. Make sure to Signed-off and GPG sign all commits you intend to merge.
- All community Pull Requests are pulled into the devel branch
- Pull Requests into devel will confirm your commits have a GPG signature, Signed-off, and a functional test before being approved
- Once your changes are merged and a more detailed review is complete, an authorized member will merge your changes into the main branch for a new release
uses:
- ansible-core 2.12
- ansible collections - pulls in the latest version based on the requirements file
- runs the audit using the devel branch
- This is an automated test that occurs on pull requests into devel
- pre-commit can be tested and can be run from within the directory
