The TaoSecurity News page says I taught 41 classes lasting a day or more, from 2002 to 2014. All of these involved some aspect of network security monitoring (NSM) Many times students would ask me when I would create the “advanced” version of the class. I could never answer them, so I decided to do so in this blog post. At some point, advanced NSM is no longer NSM, expand beyond NSM to other aspects of the cyber security landscape.”]
