I don't know if anyone's brought it up or not, but I've found that a great resources for software engineering publications is through ACM or IEEE. If you are a student, you can get a discount on registering and get access to many articles. You can find a great multitude of articles on security with examples.
In my case, I actually get free access as a student
Just wanted to bring this point up since it offers a different flavor than published books. Anyone else know any digital libraries with security articles?
