The vCenter VAMI service must enable honoring the SSL cipher order.
An XCCDF Rule
Description
<VulnDiscussion>During a Transport Layer Security (TLS) session negotiation, when choosing a cipher during a handshake, normally the client's preference is used. This is potentially problematic as a malicious, dated, or poorly configured client could select the most insecure cipher offered by the server, even if it supports stronger ones. If "ssl.honor-cipher-order" is enabled, the "ssl.cipher-list" setting will be treated as an ordered list of cipher values from most preferred to least, left to right.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
