InformationAudit /usr/bin/runc if applicable
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.
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.
SolutionYou should add a rule for /usr/bin/runc file.
Add the line below to the /etc/audit/audit.rules file:
-w /usr/bin/runc -k docker
Then restart the audit daemon.
systemctl restart auditd
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.
