Welcome to my course, Hack the Planet. These lectures are an introduction to basic practical security, or "hacking". You can also take part in the online course: http://hackthe.pl/anet.
This course assumes you have a little bit of background knowledge in programming: the students taking this course had taken a semester worth of C programming. Hopefully the lecture content should be accessible even if you haven't done any programming, although you might have to research a few concepts if you get stuck.
