Lern- und Lehrformen

Lecture and exercise.

Every week a 90 minutes lecture (in english) is held and streamed over the internet. Students have to solve and submit their exercises weekly.


50 % of the maximum exercise points (in 1st and 2nd half of semester) are needed to be able to take part in the examination at the end of the semester. In the middle of the semester (14.12.2009,  13:30?Uhr B.E 2?) there will be a written intermediate exam which counts about 1/3. At the end of the course there is a second written exam (counts about 2/3). Students who want to improve their mark can also register for an oral examination. Outstanding exercise results and participation in discussion can lead to a better mark.

There will be two practical hands-on exercises including reconnaissance, analysis, and practical attack of a prepared victim network.
