Security is difficult; open source security sometimes even more so

I have prepared a presentation on Open Source security for the Open Source Specialist Group of British Computer Society (BCS OSSG):

• A_Look_at_Open_Source_Security  (PDF)

The main aim of the presentation is to give an overview of the current state of security in open source projects. I discuss why security is difficult (hint: it's because few people care), and why security in open source is sometimes even more difficult. At the end, I give a simple 3-point strategy for quick evaluation of the security posture of open source projects.
