# Ensure audit tools group owner is configured

Necessity: The auditd tools are critical for monitoring system activity and detecting potential security breaches. Ensuring they are owned by the `root` group is essential to prevent unauthorized modification. If a non-privileged user or group could alter these tools, they could potentially disable auditing, hide malicious actions, or create false audit trails, thereby compromising the integrity of the entire system's security monitoring framework. Misconfiguration poses a severe risk of undetected intrusion and data tampering.

Auditing and Remediation: The audit script verifies the current group owner of the key auditd executable files. The remediation script uses the `chgrp` command to reset the group ownership of these critical binaries to a secure, specified group.

Recommended State Rationale: The Basic, Moderate, and Strict recommendation is uniformly `['root']`. This is because system-level security and auditing tools must be exclusively managed by the superuser to maintain their integrity. Assigning group ownership to any other group, even a dedicated administrative group, introduces an unnecessary attack vector. Any user within that group could potentially gain the ability to modify the tools, which is an unacceptable risk. Therefore, `root` ownership is the only appropriate and secure configuration for all hardening levels.

## Recommended State Configuration

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

## Audit Script Working

bash script that uses the `stat -c %G` command on the primary audit tool executables (e.g., `/sbin/auditctl`, `/sbin/aureport`, `/sbin/ausearch`). The script must verify that all tools share the same group owner and output only the name of that group.

## Remediation Script Working

bash script that accepts a single positional command-line argument representing the desired group name. The script must use the `chgrp` command to set the group ownership for all audit executables (`/sbin/auditctl`, `/sbin/aureport`, `/sbin/ausearch`, `/sbin/autrace`, `/sbin/augenrules`) to the group specified in the argument. The script must output `true` on success and `false` if any operation fails.
