Zero trust is the latest buzzword in cybersecurity and this is one of the few books on the topic after more than a decade Kindervag coined the term (now Forrester calls it ZTX) and Google implemented it with its BeyondCorp. As microservices and microsegmentation is not the best architecture for all, zero trust may not be the best investment for every business yet,but need to eventually migrate. This maybe a dry read yet a very good reference covering the basic principles and pillars as well as all related concepts.
When I read a non-fiction book that has the explicit purpose of teaching me something, I don't liked being talked down to. The writing style of this book most certainly talked down to me. If I cut out every paragraph where the authors used "of course," then I think I'd be left with half of the book. The use of language that implies that things are self-evident is annoying! If something was truly self-evident and merited using the phrase "of course," then I wouldn't be reading the book because I wouldn't be learning something!
The only reason I'm giving this book two stars is because, buried under all that dismissive language, there actually are some interesting concepts in the text. Unfortunately, I was really disappointed in the way these concepts were represented.
