CIS Docker Benchmark v1.6.0 - 1.1.10

Profile Applicability

• Level 2 - Docker - Linux

Description

Audit /etc/default/docker, if applicable.

Rationale

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.

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 associated with the /etc/default/docker file.

For example, you could execute the command below:

auditctl -l | grep /etc/default/docker

This should display a rule for the /etc/default/docker file.

Remediation

You should add a rule for the /etc/default/docker file.

For example: Add the line below to the /etc/audit/audit.rules file:

-w /etc/default/docker -k docker

Then restart the audit daemon.

For example:

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.
