Control: 1.1.11 Ensure auditing is configured for Docker files and directories - /etc/docker/daemon.json
Description
Audit the /etc/docker/daemon.json if applicable. As well as auditing the normal Linux file system and system calls, you should audit all Docker related files and directories. The Docker daemon runs with root privileges and its behavior depends on some key files and directories. /etc/docker/daemon.json is one such file. It holds various parameters related to the Docker daemon and should therefore be audited.
Remediation
You should add a rule for the /etc/docker/daemon.json file
For example,
Add the line as below to the /etc/audit/audit.rules file:
-w /etc/docker/daemon.json -k docker
Then, restart the audit daemon using the following command
systemctl restart auditd
Default Value
By default, Docker related files and directories are not audited. The file
/etc/docker/daemon.json may not exist on the system and in that case, this
recommendation is not applicable.
Usage
Run the control in your terminal:
powerpipe control run docker_compliance.control.cis_v160_1_1_11Snapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe control run docker_compliance.control.cis_v160_1_1_11 --shareSQL
This control uses a named query:
with os_output as ( select btrim(stdout_output, E' \n\r\t') as os, _ctx ->> 'connection_name' as os_conn from exec_command where command = 'uname -s'), hostname as ( select btrim(stdout_output, E' \n\r\t') as host, _ctx ->> 'connection_name' as host_conn, _ctx from exec_command where command = 'hostname'),
linux_output as ( select stdout_output, _ctx ->> 'connection_name' as conn from exec_command, os_output where os_conn = _ctx ->> 'connection_name' and command = 'sudo -n auditctl -l | grep /etc/docker/daemon.json')select host as resource, case when os.os ilike '%Darwin%' then 'skip' when o.stdout_output = '' then 'alarm' else 'ok' end as status, case when os.os ilike '%Darwin%' then host || ' /etc/containerd/config.toml does not exist on ' || os.os || ' OS.' when o.stdout_output = '' then host || ' /etc/docker/daemon.json auditing is not configured.' else host || ' /etc/docker/daemon.json auditing is configured.' end as reason , h._ctx ->> 'connection_name' as connection_namefrom hostname as h, os_output as os, linux_output as owhere os.os_conn = h.host_conn and h.host_conn = o.conn;
