Using Starwind SAN 8.0

Is there a way to authenticate iSCSI targets with passwords? We're trying to prevent an attacker from connecting to the iSCSI target and mount the iSCSI storage.
I see there is Partner Authentication Settings, is this the same thing?

I also just installed Starwind 8 build 7145 on Server 2012 R2, and was *not* presented with an option for either VSphere or Hyper-V. My license is for Hyper-V. The service that gets installed each time is "StarWind Virtual SAN for vSphere."
Is this a problem?
