Deep Dive: Exploring the Real-world Value of Open Source Intelligence 1st Edition

This is a useful desk reference for CyberSec professionals. The material in digital artifacts and detailed information on non traditional intelligence tradecraft is useful in the knowledge domains of maritime intelligence ,HUMINT, IoT, cyber physical systems and promises/threats of OSINT.Well crafted book. I highly recommend this resource.Larry Leibrock

I love the way this book doesn’t make any assumptions about past knowledge and is very well cited. Enjoy this book if you’re curious about diving into OSINT or to update your knowledge as an experienced investigator.

owning a company that does Cyber Intelligence work, this book is a treasure trove of information. I would highly recommend it to anyone in the business or just want to know what the world does that now one sees.

I feel like my life is nothing but reading cybersecurity books and articles so it was an honest pleasure to sit down with Rae Baker's book and found it both informative and entertaining. If you are a beginner in the world of Open Source Intelligence you will find this book perfect tutor for learning the field from the ground up if you have mastered OSINT (unlikely..lol) you will find the book a great resource.

It took me a while to complete reading this book. It is about 500 pages and each of them go into a good amount about the techniques relating to various types of intelligence. Rae does a great job focusing on the methods and references some tools here and there. However, it never felt like you were being bombarded by tools. I personally learned a lot, and will definitely use this knowledge in the future. For me, it was well worth the money.Sad side tangent: I was reading this book so much, that while I was reading this book, my wife left me. According to the court documents she said "He spends too much time reading the amazing OSINT book called Deep Dive: Exploring the Real-world Value of Open Source Intelligence by Rae Baker. If he left the book for even a second, we would still be together". Bad news was my wife left me. Good news is that I have new OSINT techniques and methods to work harder at becoming a great OSINT analyst.

Although the book does examine many primary sources for open source intelligence it seems to cite Wikipedia for sourcing data quite often. If you happen to have domain knowledge in a certain area this book will probably not help you to expand your knowledge base.

As an OSINT professional, I'm always looking to learn new tricks of the trade. This book not only showed me new pivots I can use in my investigations, but also explained every topic in an easy-to-understand way. Deep Dive is definitely a good entry book into OSINT, and also a great read for subject matter experts and everyone in between. One of the best parts about this book is that it doesn't focus on tools, which can become outdated, but more on critical thinking and which questions to ask to get the answers you're seeking. The use of cases and examples makes every topic come together neatly. You can tell Rae put her heart and a lot of passion into writing this. I will be recommending this book to all of my mentees.

As both an OSINT instructor and practitioner, this is the book I can easily recommend to new OSINT analysts just starting out, or give to those who may need a refresher in specific subject area. Rae thought of everything and set it out from the very beginning. She didn't wait until the end to discuss critical thinking, bias, or ethics. These are fundamental and should be discussed early and often. And, because this book is more about methodology than a running list of resources, she made sure to include OPSEC at every turn to ensure the integrity, safety and security of one's research. For those in the OSINT community, this is the page turner you've been waiting for.
