1.1.18 Ensure auditing is configured for Docker files and directories - /usr/bin/runc

Information

Audit /usr/bin/runc if applicable

Rationale:

As well as auditing the normal 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. /usr/bin/runc is one such file, and as such it should be 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 /usr/bin/runc file.
For example:
Add the line below to the /etc/audit/audit.rules file:

-w /usr/bin/runc -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 /usr/bin/runc may not be present on the system and in that case this recommendation is not applicable.
