1.1.7 Ensure auditing is configured for Docker files and directories - docker.service

Information

Audit the docker.service if applicable.

Rationale:

As well as auditing the normal 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 with docker.service being one such file. The docker.service file might be present if the daemon parameters have been changed by an administrator. If so, it holds various parameters for the Docker daemon and should be audited.

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.

Solution

If the file exists, a rule for it should be added.
For example:
Add the line as below in /etc/audit/audit.rules file:

-w /usr/lib/systemd/system/docker.service -k docker

Then restart the audit daemon.
For example:

systemctl restart auditd

Default Value:

By default, Docker related files and directories are not audited. The file docker.service may not be present on the system.
