In the world of network traffic analysis and network security monitoring, free and open discourse is extremely important. Analytical techniques that are subject to discussion and critique will always be better than those that aren't. Quite simply put, analysts cannot thrive in a bubble, and neither can a robust network security monitoring program.
Unfortunately, there are some organizations that keep their analysts insulated, for whatever reason. These organizations tend to wall themselves off from the free exchange of ideas. In my experience, this hurts those organizations, as their analysts often fall behind the collective intelligence.
The good news is that ideas are always willing to be heard if someone is willing to listen.
