This weekend I taught the second part of Security Networking at Master on Free Software. After studying networking foundations, enjoying some practical labs and going on Linux networking stack in depth we finished with practical attacks and defenses as usual.
By the way, I coincided with MSWL students and several students of previous editions at Brussels attending to FOSDEM too. Drinking some beers and chatting about free and open technology was nice. This shot catched some students while sharing their keys at the FOSDEM's keysigning event :)
