InformationAudit docker.sock, if applicable.
As well as auditing the normal Linux file system and system calls, you should also audit the Docker daemon. Because this daemon runs with root privileges, it is very important to audit its activities and usage. Its behavior depends on some key files and directories with docker.socket being one such file, and as this holds various parameters for the Docker daemon, 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.
SolutionIf the file exists, you should add a rule for it.
Add the line below to the /etc/audit/rules.d/audit.rules file:
-w /var/run/docker.sock -k docker
Then restart the audit daemon.
systemctl restart auditd
By default, Docker related files and directories are not audited. The file docker.sock may not be present, but if it is, it should be audited.
