Control: 1.1.4 Ensure auditing is configured for Docker files and directories - /run/containerd

Description

Audit /run/containerd.

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 behaviour depends on some key files and directories. /run/containerd is one such directory. As it holds all the information about containers it should be audited.

Remediation

You should add a rule for the /run/containerd directory. For example, Add the line as below to the /etc/audit/audit.rules file:

-a exit,always -F path=/run/containerd -F perm=war -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.

Usage

Run the control in your terminal:

powerpipe control run docker_compliance.control.cis_v160_1_1_4

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run docker_compliance.control.cis_v160_1_1_4 --share

This control uses a named query:
