The vCenter Server must disable the distributed virtual switch health check.
An XCCDF Rule
Description
<VulnDiscussion>Network health check is disabled by default. Once enabled, the health check packets contain information on host#, vds#, and port#, which an attacker would find useful. It is recommended that network health check be used for troubleshooting and turned off when troubleshooting is finished.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
