# Ensure audit tools group owner is configured

Necessity: Properly configuring the group owner for audit log directories is crucial for maintaining the integrity and confidentiality of audit trails. If an unauthorized group owns the directory, users within that group could potentially read, modify, or delete sensitive audit records, effectively blinding security monitoring and covering up malicious activities. This control enforces the principle of least privilege, ensuring that only authorized administrative personnel or processes can access critical security logs.

Auditing and Remediation: The audit script verifies the current group owner of the '/var/log/audit/' directory using file system metadata. The remediation script utilizes the 'chgrp' command to set the group ownership to a specified, more secure group, thereby restricting access to the audit logs.

Recommended State Rationale:
- Basic: Setting the group to 'root' is the default and provides a fundamental level of security, as only the superuser can manage the logs.
- Moderate: Using the 'adm' group is a common administrative practice. It allows system administrators and specific daemons that are part of this group to access logs without requiring full root privileges, which can be beneficial for log management and analysis tools.
- Strict: Creating and using a dedicated 'audit' group is the most secure configuration. This approach adheres strictly to the principle of least privilege by isolating audit log access to only those users or services explicitly placed in the 'audit' group, significantly minimizing the risk of unauthorized access or tampering.

## Recommended State Configuration

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

## Audit Script Working

Bash script that retrieves the group owner of the '/var/log/audit/' directory. The script must output only the group name, with no additional text or formatting.

## Remediation Script Working

Bash script that accepts a single positional argument, which is the desired group name. The script must change the group owner of the '/var/log/audit/' directory to the provided name. It must return 'true' on success and 'false' on failure.
