# 6.3.4.9 Ensure audit tools owner is configured (Automated)

## Profile Applicability

- Level 2 - Server
- Level 2 - Workstation

## Description

Audit tools include, but are not limited to, vendor-provided and open source audit tools needed to successfully view and manipulate audit information system activity and records. Audit tools include custom queries and report generators.

## Rationale

Protecting audit information includes identifying and protecting the tools used to view and manipulate log data. Protecting audit tools is necessary to prevent unauthorized operation on audit information.

## Audit

Run the following command to verify the audit tools are owned by the `root` user:

```bash
stat -Lc "%n %U" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/augenrules | awk '$2 != "root" {print}'
```

Nothing should be returned.

## Remediation

Run the following command to change the owner of the audit tools to the `root` user:

```bash
chown root /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/augenrules
```
