The book addresses the concept, value as well as practical application of Open Source Intelligence (OSINT) in various domains related to policing and national security from law enforcement and defense to security services and cyber-security. It provides a comprehensive view into the newest methologies for OSINT analytics and visualizations combined with real-life case studies to showcase the application as well as challenges of OSINT investigations across domains. It further provides guidance on legal and ethical considerations, making it relevant reading for practitioners as well as academics and students with a view to obtain thorough, first-hand knowledge from serving experts in the field.
Like any anthology, some essays were better/more interesting than others, but all seemed high-quality. Some were overly technical/narrow and, as is the nature of technology-focused writings, many feel already out-of-date, despite recent publication.
I had to read about half of this book for a course, but I wanted to read the other half for myself, and I'm glad I did. A lot of essays in particular gave me food for thought or touched on topics (new or familiar) in interesting ways. I wouldn't necessarily recommend it for casual reading, but there are certainly essays that I would extract to share with colleagues or fellow students.
