In this first part, we set the stage for this book. We present how we think about security, development, and how they fit together. We analyze where problems tend to occur and what we think can be done about it. The opening chapter covers these aspects, together with an example of what we mean by secure by design.

We finish this part with an intermission chapter that is more of a light read. Here, we introduce some of the ideas of the next part through a case study from a client we’ve worked with. So, let’s get started with how security and development fit together, and the basic ideas behind secure by design.
