# The /usr/sbin/runc executable should be audited, if applicable
Classification:complianceFramework:cis-dockerControl:1.2.12 
## Description{% #description %}

Audit `/usr/sbin/runc`, if applicable.

## Rationale{% #rationale %}

As well as auditing the Linux file system and system calls, you should also audit all Docker-related files and directories. The Docker daemon runs with root privileges and its behavior depends on some key files and directories, including `/usr/sbin/runc`, and so it should be audited.

## Audit{% #audit %}

Verify that there is an audit rule corresponding to the `/usr/sbin/runc` file. To display the rule for the `/usr/sbin/runc` file, run:

```bash
auditctl -l | grep /usr/sbin/runc
```

## Remediation{% #remediation %}

You should add a rule for the `/usr/sbin/runc` file. For example, add the following line to a new file in `/etc/audit/rules.d/`. For instance, create a file named `docker.rules`:

```bash
echo "-w /usr/sbin/runc -k docker" > /etc/audit/rules.d/docker.rules
```

Then, reload the audit rules:

```bash
augenrules --load
```

Next, restart the audit daemon using the following command:

```bash
service auditd restart
```

## Impact{% #impact %}

Auditing can generate large log files. You should ensure that these are rotated and archived periodically. A separate partition should also be created for audit logs to avoid filling up any other critical partition.

## Default value{% #default-value %}

By default, Docker-related files and directories are not audited. The file `/usr/sbin/runc` may not be present on the system, and in that case, this recommendation is not applicable.
