Auditing for the Docker daemon configuration file is configured








Set up the docker integration.


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


As well as auditing Linux file system and system calls, you should also audit all Docker related files and directories. The Docker daemon runs with root privileges and its behavior depends on some key files and directories, including /etc/docker/daemon.json. This holds various parameters for the Docker daemon, and so it should be audited.


Verify that there is an audit rule associated with the /etc/docker/daemon.json file. To display the rule for the /etc/docker/daemon.json file, run:

auditctl -l | grep /etc/docker/daemon.json


You should add a rule for the /etc/docker/daemon.json file. For example, add the following line to the /etc/audit/audit.rules file:

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

Then restart the audit daemon:

service auditd restart


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.

Default value

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