Details
Audit /usr/bin/docker-runc, 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. /usr/bin/docker-runc is one such file. Docker now relies on containerd and runC to spawn containers. It must be audited, if applicable.
Solution
Add a rule for /usr/bin/docker-runc file.
For example,
Add the line as below in /etc/audit/audit.rules file:
-w /usr/bin/docker-runc -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/usr/bin/docker-runc may not be available on the system. In that case, this recommendation is not applicable.
