I will be teaching a guest lecture on "Security" for the "Computer Infrastructures" course that is taught at our department. The request of the teacher is that it is "a little bit technical" and last anywhere between one and two hours. I am taking suggestions for a lecture outline :-)

Oh; a day later, I will also be presenting AIRT at a SURFnet seminar. If you're interested to attend, please sign up. Attendance is free, in both senses of the word.
