1.11 Audit Docker files and directories - /etc/docker/daemon.json

Information

Audit /etc/docker/daemon.json, if applicable.

Rationale:

Apart from auditing your regular Linux file system and system calls, audit all Docker related files and directories. Docker daemon runs with 'root' privileges. Its behavior depends on some key files and directories. /etc/docker/daemon.json is one such file. It holds various parameters for Docker daemon. It must be audited, if applicable.

Solution

Add a rule for/etc/docker/daemon.jsonfile.

For example,

Add the line as below in /etc/audit/audit.rules file:

-w /etc/docker/daemon.json -k docker

Then, restart the audit daemon. For example,

service auditd restart

Impact:

Auditing generates quite big log files. Ensure to rotate and archive them periodically. Also, create a separate partition of audit to avoid filling root file system.


Default Value:

By default, Docker related files and directories arenot audited.The file /etc/docker/daemon.json may not be available on the system. In that case, this recommendation is not applicable.
