Docker Enterprise server certificate file permissions must be set to 444 or more restrictive.

Description

<VulnDiscussion>Verify that the Docker server certificate file (the file that is passed along with --TLScert parameter) has permissions of 444 or more restrictive. The Docker server certificate file should be protected from any tampering. It is used to authenticate Docker server based on the given server certificate. Hence, it must have permissions of 444 to maintain the integrity of the certificate. By default, the permissions for Docker server certificate file might not be 444. The default file permissions are governed by the system or user specific umask values.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
