# Ensure audit configuration files group owner is configured

The integrity of the system's audit logs is paramount for security monitoring and forensic analysis. The auditd configuration files in `/etc/audit/rules.d/` dictate what system activities are logged. If these files can be modified by unauthorized users, an attacker could alter the rules to stop logging their malicious actions, effectively rendering them invisible to system administrators and security tools. Restricting group ownership to `root` ensures that only the superuser can manage audit rules, preventing tampering and upholding the principle of least privilege. The audit script verifies that all files in the audit rules directory are owned by the `root` group. The remediation script corrects any deviations by using the `chgrp` command to reset the group ownership to `root`. All recommended security levels (Basic, Moderate, and Strict) mandate `root` as the group owner. There is no less-secure-but-acceptable alternative; any group other than `root` introduces an unacceptable risk of audit system compromise. This strict requirement is a foundational security control for maintaining a trustworthy audit trail.

## Recommended State Configuration

| Security Level | Value |
|----------------|-------|
| **Basic** | `['root']` |
| **Moderate** | `['root']` |
| **Strict** | `['root']` |
| **Type** | `ENUM` |

## Audit Script Working

Bash script to check the group owner of all configuration files within the `/etc/audit/rules.d/` directory. If all files are owned by the `root` group, the script must output the string `root`. If any file is owned by a different group, the script should output the group name of the first file found that is not owned by `root`. If the directory does not exist or contains no files, the script should output `Not Applicable`.

## Remediation Script Working

Bash script that accepts one positional command-line argument, which is the desired group name (e.g., `root`). The script must use this argument to set the group ownership for all files located in the `/etc/audit/rules.d/` directory. The script must output `true` upon successful completion or `false` if an error occurs.
