Cis Docker V160 1.1.4

CIS Docker Benchmark v1.6.0 - 1.1.4

Profile Applicability

• Level 1 - Docker - Linux
• Level 2 - Docker - Linux

Description

Audit /run/containerd.

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 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.

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.

Audit Procedure

You should verify that there is an audit rule applied to the /run/containerd directory. For example, you could execute the command below:

auditctl -l | grep /run/containerd

This should list a rule for the /run/containerd directory.

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.
