Virtualization both simplifies and complicates networking environments for IT pros.

Virtualization improves the operational flexibility of IT assets. That’s a fact most IT professionals know first-hand at this point. However, at the same time, virtualization also serves to complicate your network environment. What once were individual machines one could point to while speaking their names are now virtualized away into an infrastructure designed specifically to make them mobile. 

That mobility, whether through VMware’s vMotion or Microsoft Hyper-V’s Live Migration, ensures the highest uptime. That mobility also introduces a host of potential issues related to security. 

If VMs are moving about, how can they be controlled? If they can be anywhere, how can you apply controls?

Luckily, virtualization’s stunningly-quick embrace by IT has driven high-level security guidance at a pace faster than this wholesale shift in mindset might otherwise have seen. Consider these three tips as critical steps towards enhancing network security across your dynamic virtual environment.
