Security and Privacy Lunch

People interested in network security and privacy meet once a week over lunch break and watch videos related to security and privacy recorded at high-quality scientific conferences (IEEE Security and Privacy, ACM CCS, NDSS, NSDI, USENIX Security, ACM SIGCOMM, ...). After the presentation, there will likely be a short discussion and brainstorming related to the presentation. This is a great way to spend your lunch break and keep pace with cutting edge security and privacy research. Watching and talking about scientific presentations often leads to interesting new ideas, possibly laying the foundation for your future thesis topic.
