This is Matt Luallen, my instructor for the Security Essentials class by SANS. This guy is an amazing instructor and he made the course so worth it. He's an IT Security expert, he knows his stuff, and he's really smart. He has his own security consulting company called Sph3r3, and lectures at DePaul University among many other things. If you get the chance, don't hesitate to attend any of his conferences, lectures, or courses. He's highly recommend. Thanks Matt for a great week of learning!
