Docker Enterprise Universal Control Plane (UCP) must be configured to use TLS 1.2.
An XCCDF Rule
Description
<VulnDiscussion>By default docker UCP is configured to use TLS v1.2, if this setting is misconfigured, older protocols containing security weaknesses could be utilized. TLS requires a handshake between client and server which is where the TLS version utilized in the connection is negotiated. For DoD use cases, all TLS must be at version 1.2.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
