Docker Enterprise docker.socket file permissions must be set to 644 or more restrictive.
An XCCDF Rule
Description
<VulnDiscussion>Verify that the docker.socket file permissions are correctly set to 644 or more restrictive. docker.socket file contains sensitive parameters that may alter the behavior of Docker remote API. Hence, it should be writable only by root to maintain the integrity of the file. This file may not be present on the system. In that case, this recommendation is not applicable. By default, if the file is present, the file permissions for this file are correctly set to 644.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
