Cis Docker V170 1.1.3

CIS Docker Benchmark v1.7.0 - Control 1.1.3

Profile

• Level: 1 - Docker - Linux
• Assessment Status: Automated

Description

Audit all Docker daemon activities.

Rationale

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.

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

Verify that there are audit rules for the Docker daemon. For example, you could execute the following command:

auditctl -l | grep /usr/bin/dockerd

This should show the rules associated with the Docker daemon.

Remediation

You should add rules for the Docker daemon. For example: Add the line below to the /etc/audit/rules.d/audit.rules file:

-w /usr/bin/dockerd -k docker

Then, restart the audit daemon using the following command

systemctl restart auditd

Default Value

By default, the Docker daemon is not audited.
