VCWN-06-000012 - The system must disable the distributed virtual switch health check.
Information
Network Healthcheck is disabled by default. Once enabled, the healthcheck packets contain information on host#, vds#, port#, which an attacker would find useful. It is recommended that network healthcheck be used for troubleshooting, and turned off when troubleshooting is finished.NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
Solution
From the vSphere Web Client go to Networking >> Select a distributed switch >> Manage >> Settings >> Health Check. Click the edit button and disable both health checks.or
From a PowerCLI command prompt while connected to the vCenter server run the following command:
Get-View -ViewType DistributedVirtualSwitch | ?{($_.config.HealthCheckConfig | ?{$_.enable -notmatch 'False'})}| %{$_.UpdateDVSHealthCheckConfig(@((New-Object Vmware.Vim.VMwareDVSVlanMtuHealthCheckConfig -property @{enable=0}),(New-Object Vmware.Vim.VMwareDVSTeamingHealthCheckConfig -property @{enable=0})))}
