Docker Enterprise server certificate key file ownership must be set to root:root.

Description

<VulnDiscussion>Verify that the Docker server certificate key file (the file that is passed along with --TLSkey parameter) is owned and group-owned by root. The Docker server certificate key file should be protected from any tampering or unneeded reads. It holds the private key for the Docker server certificate. Hence, it must be owned and group-owned by root to maintain the integrity of the Docker server certificate. By default, the ownership and group-ownership for Docker server certificate key file is correctly set to root.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
