# The Docker socket file should have permissions of 660 or stricter
Classification:complianceFramework:cis-dockerControl:3.16 
## Description{% #description %}

You should verify that the Docker socket file has permissions of 660 or are configured more restrictively.

## Rationale{% #rationale %}

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.

## Audit{% #audit %}

Verify that the Docker socket file has permissions of `660` or more restrictive, by running:

```gdscript3
stat -c %a /var/run/docker.sock
```

## Remediation{% #remediation %}

Run the command `chmod 660 /var/run/docker.sock`

This sets the file permissions of the Docker socket file to 660.

## Impact{% #impact %}

None

## Default value{% #default-value %}

By default, the permissions for the Docker socket file is correctly set to 660.
