Summary

In this chapter, I outlined some of the core principles you should adopt when building software today. In my experience, none of these principles are hard to implement, yet the rewards are huge. You should adopt each of these concepts within your development organization as soon as possible. If you had to choose one principle to get you started, choose Employ secure defaults because doing so will reduce the potential attack population (and it leads nicely to Use defense in depth and Use least privilege ). A close second would be Learn from mistakes. It's all very well making a mistake we're human, and we make mistakes. Just don't keep making the same mistakes!
