Control: 1.1.11 Ensure auditing is configured for Docker files and directories - /etc/docker/daemon.json

Description

Audit the /etc/docker/daemon.json if applicable. As well as auditing the normal Linux file system and system calls, you should audit all Docker related files and directories. The Docker daemon runs with root privileges and its behavior depends on some key files and directories. /etc/docker/daemon.json is one such file. It holds various parameters related to the Docker daemon and should therefore be audited.

Remediation

You should add a rule for the /etc/docker/daemon.json file For example, Add the line as below to the /etc/audit/audit.rules file:

-w /etc/docker/daemon.json -k docker

Then, restart the audit daemon using the following command

systemctl restart auditd

Default Value

By default, Docker related files and directories are not audited. The file /etc/docker/daemon.json may not exist on the system and in that case, this recommendation is not applicable.
