1.1.12 Ensure auditing is configured for Docker files and directories - /etc/containerd/config.toml


Audit /etc/containerd/config.toml 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 and /etc/containerd/config.toml is one such file as it contains various parameters. If present, it is important that it is 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.


You should add a rule for /etc/containerd/config.toml file.
For example:
Add the line below to the /etc/audit/audit.rules file:

-w /etc/containerd/config.toml -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 /etc/containerd/config.toml may not be present on the system and in that case, this recommendation is not applicable.
