You should verify that the Docker socket file has permissions of 660 or are configured more restrictively.
Only root and the members of the docker group should be allowed to read and write to the default Docker Unix socket. The Docker socket file should therefore have permissions of 660 or more restrictive permissions.
None.
You should execute the command below to verify that the Docker socket file has permissions of 660 or more restrictive permissions
stat -c %a /var/run/docker.sock
You should execute the command below.
chmod 660 /var/run/docker.sock
This sets the file permissions of the Docker socket file to 660.
By default, the permissions for the Docker socket file is correctly set to 660.
| Controls Version | Control | IG 1 | IG 2 | IG 3 |
|---|---|---|---|---|
| v8 | 3.3 Configure Data Access Control Lists Configure data access control lists based on a user's need to know. Apply data access control lists, also known as access permissions, to local and remote file systems, databases, and applications. | ● | ● | ● |
| v7 | 14.6 Protect Information through Access Control Lists Protect all information stored on systems with file system, network share, claims, application, or database specific access control lists. These controls will enforce the principle that only authorized individuals should have access to the information based on their need to access the information as a part of their responsibilities. |
