Windows 2012 Hyper-V brought a lot of new features. There are many improvements in security as well:
•DHCP Guard is a security feature that drops DHCP server messages from unauthorized virtual machines pretending to be DHCP servers.
•Router Guard is a security feature that drops Router Advertisement and Redirection messages from unauthorized virtual machines pretending to be routers.
•Port Mirroring duplicates all egress and ingress traffic to/from one or more switch ports (being monitored) to another switch port (performing monitoring)
These settings are configured per Virtual Machine and Virtual Switch. To configure :
- Open the Hyper-V Manager and then select the Virtual Machine (e.g. W2012-FS01)
- On the right panel, click on Settings.
- Select the Virtual Switch (e.g. v-External-Wired) you want to configure and expand Advanced Features.
