ENI is a one-day course designed to teach all methods of network traffic access. If you register before 6 June you will save $250. If you take a full SANS track my class only costs $450. This is the only time I’ll be teaching this class in 2007.Update: I cancelled the class. Please email me privately if you want reasons for canceling the class, or if you need to have a reason to do so. Please note SANS set all of these prices and schedules.”]
