## 🚨 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.
- Testing is the most important thing you can do.
- 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.
- Check Mode is not guaranteed! 🚫 The role will complete in check mode without errors, but it is not supported and should be used with caution.
- 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.
- 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
- To use release version please point to main branch and relevant release for the cis benchmark you wish to work with.
- Did we mention testing??

## Coming From A Previous Release ⏪
CIS release always contains changes, it is highly recommended to review the new references and available variables. This have changed significantly since ansible-lockdown initial release.
This is now compatible with python3 if it is found to be the default interpreter. This does come with pre-requisites which it configures the system accordingly.
Further details can be seen in the [Changelog](./ChangeLog.md)

## Role Variables
This role is designed that 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.
## Tags
## Tags 🏷️
There are many tags available for added control precision. Each control has it's own set of tags noting what level, if it's scored/notscored, what OS element it relates to, if it's a patch or audit, and the rule number.
There are many tags available for added control precision. Each control has its own set of tags noting what level, what OS element it relates to, whether it's a patch or audit, and the rule number. Additionally, NIST references follow a specific conversion format for consistency and clarity.
### Conversion Format for NIST References:
1. Standard Prefix:
- All references are prefixed with "NIST".
2. Standard Types:
- "800-53" references are formatted as NIST800-53.
- "800-53r5" references are formatted as NIST800-53R5 (with 'R' capitalized).
- "800-171" references are formatted as NIST800-171.
3. Details:
- Section and subsection numbers use periods (.) for numeric separators.
- Parenthetical elements are separated by underscores (_), e.g., IA-5(1)(d) becomes IA-5_1_d.
- Subsection letters (e.g., "b") are appended with an underscore.
Below is an example of the tag section from a control within this role. Using this example if you set your run to skip all controls with the tag services, this task will be skipped. The opposite can also happen where you run only controls tagged with services.

- ansible-core 2.16
- ansible collections - pulls in the latest version based on requirements file
- runs the audit using the devel branch
- This is an automated test that occurs on pull requests into devel
- self-hosted runners using OpenTofu
## Known Issues
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.
