Control: 1.1.10 Ensure auditing is configured for Docker files and directories - /etc/default/docker

Description

Audit the /etc/default/docker 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/default/docker 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/default/docker file For example, Add the line as below to the /etc/audit/audit.rules file:

-w /etc/default/docker -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 so these defaults should be changed in line with organizational security policy. The file /etc/default/docker may not be present, and if so, this recommendation is not applicable.
