I wanted to report regularly on the preparations for the next semester. There is a project and a course in system security to be prepared. And as usual I want to improve the material I have at hand. System security is split up in two parts: Vulnerabilities and Countermeasures — or Attack and Defense, if you want. For the masters project I have proposed to set up PalaestrAI in the lab to train attack and defense agents — or at least explore the methods available nowadays. Let's see what is possible with the available computing power and creativity. The main task of the next week will be to set up a fundamental scenario (that's the term for a configuration of a set of virtual machines and networks in our lab setup tool). But the first steps are always cleaning up the servers, preparations and planning. I started with sketching the scenario and discussing it with lab staff and collecting source code and repositories. (But as the last semester is not completed yet, there is still grading and examinations to be done. I set a personal record of grading the written exams for math in only 3 days. Next week I'll do the same for IT-security.)
