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 First, I love the historical references to our profession.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.

Cute book for babies!
Format: Board book
Bought this for my best friend’s daughter for her 1st birthday along with some other little beach items. Me and her both have many fond memories of our beach trips throughout the years together. We both have daughters 2 months apart and can not WAIT for all our future girls beach trips together! 🏖️ She absolutely loved this adorable little book for her little one!
