Chapter 1: Introduction to Cyber Threat Intelligence, Analytical Models, and Frameworks
Generally speaking, there are a few "shiny penny" terms in modern IT terminology – blockchain, artificial intelligence, and the dreaded single pane of glass are some classic examples. Cyber Threat Intelligence (CTI) and threat hunting are no different. While all of these terminologies are tremendously valuable, they are commonly used for figurative hand-waving by marketing and sales teams to procure a meeting with a C-suite. With that in mind, let's discuss what CTI and threat hunting are in practicality, versus as umbrella terms for all things security.
Through the rest of this book, we'll refer back to the theories and concepts that we will cover here. This chapter will focus a lot on critical thinking, reasoning processes, and analytical models; understanding these is paramount because threat hunting is not linear. It involves constant adaption with a live adversary on the other side of the keyboard. As hard as you are working to detect them, they are working just as hard to evade detection. As we'll discover as we progress through the book, knowledge is important, but being able to adapt to a rapidly changing scenario is crucial to success.
In this chapter, we'll go through the following topics:
- What is cyber threat intelligence?
- The Intelligence Pipeline
- The Lockheed Martin Cyber Kill Chain
- Mitre's ATT&CK Matrix
- The Diamond Model
