Control: 1.1.9 Ensure auditing is configured for Docker files and directories - docker.socket

Description

Audit the containerd.sock if applicable. As well as auditing the normal Linux file system and system calls, you should also audit the Docker daemon. Because this daemon runs with root privileges, it is very important to audit its activities and usage. Its behavior depends on some key files and directories with containerd.sock being one such file, and as this holds various parameters for the Docker daemon, it should be audited.

Remediation

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

-w /run/containerd/containerd.sock -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 containerd.sock may not be present, but if it is, it should be audited.
