Many people in the information security field strongly suspected that government eavesdropping was pervasive.

Many IT organizations met this recommendation with either confusion (What’s a SQL injection?) or disbelief (Why would someone try to do that?). Often, the former audience was the network engineering…

Well, there is a missing link in the chain, namely security. The promise of SDN is the ability to define data paths via the network that are optimized for scale and efficiency. Tried and true technologies such as routing…
