Description

Security and Usability; pick one at the expense of the other is the story we've all heard time and again. More secure systems are harder to use; for example longer secure passwords are harder to remember than shorter, more easily guessed ones.



In the real world it has been recently noticed that when security "gets in the way"; it is often circumvented by the users. For example, systems that "upgrade security" by requiring lengthy passwords often result in sticky notes appearing as people begin to write their passwords down. The book explores a number of topics from the perspective that improved usability can enhance the real world security of a system.



The chapters are written by different authors and grouped around related topics. It's hard to pull off these kinds of books well, but I believe this one succeeds. I put the chapters into three categories; talking points, patterns I can use, and presentations.



Talking point chapters help me explain to others how improving usability can improve security; examples include "Usable Security" and "Design for Usability". Patterns I can use chapters present a framework for evaluating different approaches to common security problems; such as evaluating authentication mechanisms. Presentation chapters discuss a particular topic presenting pros and cons, such as "Identifying Users from Their Type Patterns" or "Informed Consent by Design".



I enjoyed reading this book. If you're considering buying or designing a secure system I recommend checking it out.
