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.

Required Programming Skills
The lecture Network Security teaches security from a very practical point of view. This includes hands-on exercises, hacks and the development of countermeasures.
For students participating in the lecture it is mandatory to have basic programming skills. We are providing a self-test, which shows the level of your skills and tells you if you are capable to deal with the practical tasks. A "network programming" crash course is offered for those who might need a fresh-up in that area (c.f. below)
"Network Programming" crash course
We will also provide a "network programming" crash/fresh-up course as additional offer during the first two weeks of the lecture. The course does not teach basic programming but helps people that are not familiar with network programming to cope with the practical exercises more easily. The dates are:
Mailing List - "Network-Security"
The mailing list "Network-Security" is used for news concerning the lecture "Network Security". An additional purpose is to discuss problems, e.g. with viewing or printing slides or assignment sheets. More information on subscribing the mailing list can be found here.
