## Caution(s)
This role **will make changes to the system** which may have unintended consequences. This is not an auditing tool but rather a remediation tool to be used after an audit has been conducted.
Check Mode is not supported! The role will complete in check mode without errors, but it is not supported and should be used with caution. The RHEL9-CIS-Audit role or a compliance scanner should be used for compliance checking over check mode.
- Testing is the most important thing you can do.
This role was developed against a clean install of the Operating System. If you are implementing to an existing system please review this role for any site specific changes that are needed.
- Check Mode is not supported! The role will complete in check mode without errors, but it is not supported and should be used with caution. The RHEL9-CIS-Audit role or a compliance scanner should be used for compliance checking over check mode.
To use the release version, please point to the `main` branch and relevant release for the cis benchmark you wish to work with.

- To use release version please point to main branch and relevant release/tag for the cis benchmark you wish to work with.
- If moving across major releases e.g. v2.0.0 - v3.0.0 there are significant changes to the benchmarks and controls it is suggested to start as a new standard not to upgrade.
- Containers references vars/is_container.yml this is an example and to be updated for your requirements

## Coming from a previous release
CIS release always contains changes, it is highly recommended to review the new references and available variables. This has changed significantly since the ansible-lockdown initial release.
This is now compatible with python3 if it is found to be the default interpreter. This does come with prerequisites which configure the system accordingly.

## Auditing (new)
This can be turned on or off within the `defaults/main.yml` file with the variables `setup_audit` and `run_audit`. The value is `false` by default. Please refer to the wiki for more details. The defaults file also populates the goss checks to check only the controls that have been enabled in the ansible role.

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](https://github.com/goss-org/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 try to remove [false positives](https://www.mindpointgroup.com/blog/is-compliance-scanning-still-relevant/) in the process.

## Example Audit Summary
This is based on a vagrant image with selections enabled. e.g. No Gui or firewall.
Note: More tests are run during audit as we check config and running state.

## Known Issues
CIS 1.2.4 - repo_gpgcheck is not carried out for RedHat hosts as the default repos do not have this function. This also affect EPEL(not covered by var).
- Rocky and Alma not affected.
Variable used to unset.
rhel9cis_rhel_default_repo: true # to be set to false if using repo that does have this ability
Almalinux BaseOS, EPEL and many cloud providers repositories, do not allow gpgcheck(rule_1.2.1.2) or repo_gpgcheck (rule_1.2.1.3) this will cause issues during the playbook unless or a workaround is found.

## Local Testing
- Ansible
Molecule can be used to work on this role and test in distinct _scenarios_.
- ansible-base 2.10.17 - python 3.8
- ansible-core 2.13.4 - python 3.10
