Lecture: Network Security

You want to know how today’s attacks against networks work? You want to learn about countermeasures and how to secure your network? Then this is your lecture! The lecture introduces actual threats on and attacks against computer networks (e.g. worms, bot-nets). You will gain a practical insight into their functioning and damage potential. During the lecture, you will be hacking systems yourself, but also learn about security protocols and state-of-the-art defense measures, including Intrusion Detection Systems and Honeypots. So, if you are interested in network security and willing to work, we would be happy to see you in the first lecture.
