1.1.13 Ensure auditing is configured for Docker files and directories - /etc/sysconfig/docker

Information

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.

Solution

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 presemt on the system and in that case, this recommendation is not applicable.
