Context, Strategies and Wisdom in a single package
Format: Kindle
This was my first book I have read by this particular author. I had spent some time looking for a comphrensive approach to Cyber Security and found many other texts to be lacking. Certain aspects are well documented, but no single source that brought it all together. This is exactly what First Principles brings to the table. As a practicioner that looks for better ways to formulate the objectives of SecOps Use Cases I have found the methods presented in this book to be immensely helpful. I have also given copies aways as a gifts to students who are just entering the field as this is by far the best intro to the long history of Cyber Security that combines the best direction for the future. The historical context that the author brings through first hand experience is beyond a treasure trove. It has been said many times in cheezy ads, but honestly, if you only read one book on Cyber Security make it this one.

Every cybersecurity professional should read this book, probably twice
Format: Audiobook
This is the Phoenix Project for cybersecurity professionals.
Every chapter of this book brought clarity and a new perspective from the way industry approaches aspects of cybersecurity. The book won’t be all things to everyone, nor is it perfect, but its the single most practical and effective approach to cybersecurity I’ve found. In a time where IT is excruciatingly complex and securing environments seems like an impossible task, this has been invaluable and has affected how I think about the future.
Im not associated with the author in any way. Im just in a leadership role facing these challenges every day and I think this book may some day become mandatory reading in the field.

Actionable and pragmatic
Format: Paperback
Rick Howard's Cybersecurity First Principles is an excellent read on numerous fronts. First, I love the historical references to our profession. Second, Rick provides actionable guidance on how to make our organizations and the security programs we build more resilient. The pragmatism of Rick's recommendations cannot be overstated. You'll need a couple of pens handy given how much of the book you are likely to underline as on-going references. This is a must-read book.

Great read. Well laid out.
Format: Paperback
You can tell Rick has years of experience in the field and this book is a great distillation and alignment of security to first principle thinking. Only thing better than the book IMO is the clear passion of the author. This is certainly a must read for any cybersecurity professional.
