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.
If the file exists, you should add a rule for it. For example: Add the line: '-w /var/run/docker.sock -k docker' to the /etc/audit/audit.rules file. Then, restart the audit daemon using the following command: systemctl restart auditd
