1.11 Audit Docker files and directories - docker.socket

Information

Audit docker.socket,if applicable.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. docker.socketis one such file. It holds various parameters for Docker daemon socket. It must be audited, if applicable.

Solution

If the file exists, add a rule for it.
For example,
Add the line as below in /etc/audit/audit.rules file-
-w /usr/lib/systemd/system/docker.socket -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 are not audited.The file docker.socket may not be available on the system.
