Cis Docker 1.1.13

Ensure auditing is configured for Docker files and directories - /etc/sysconfig/docker (Automated)

Description

Audit /etc/sysconfig/docker if applicable

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. Its behavior depends on some key files and directories and /etc/sysconfig/docker is one such file as it contains various parameters related to the Docker daemon when run on CentOS and RHEL based distributions. If present, it is important that it is 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

You should verify that there is an audit rule present relating to the /etc/sysconfig/docker file.

For example, you could execute the command below:

auditctl -l | grep /etc/sysconfig/docker

This should display a rule for /etc/sysconfig/docker file.

Remediation

You should add a rule for /etc/sysconfig/docker file.

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

-w /etc/sysconfig/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. The file /etc/sysconfig/docker may not be present on the system and in that case, this recommendation is not applicable.
