Operationalizing Threat Intelligence

By: Kyle Wilhoit, Joseph Opacki

Overview of this book

We’re living in an era where cyber threat intelligence is becoming more important. Cyber threat intelligence routinely informs tactical and strategic decision-making throughout organizational operations. However, finding the right resources on the fundamentals of operationalizing a threat intelligence function can be challenging, and that’s where this book helps. In Operationalizing Threat Intelligence, you’ll explore cyber threat intelligence in five fundamental areas: defining threat intelligence, developing threat intelligence, collecting threat intelligence, enrichment and analysis, and finally production of threat intelligence. You’ll start by finding out what threat intelligence is and where it can be applied. Next, you’ll discover techniques for performing cyber threat intelligence collection and analysis using open source tools. The book also examines commonly used frameworks and policies as well as fundamental operational security concepts. Later, you’ll focus on enriching and analyzing threat intelligence through pivoting and threat hunting. Finally, you’ll examine detailed mechanisms for the production of intelligence. By the end of this book, you’ll be equipped with the right tools and understand what it takes to operationalize your own threat intelligence function, from collection to production.

Summary

In this chapter, we introduced you to the concept of similarity analysis to help you with your pivoting and hunting journey. Specifically, we talked about the motivations for doing similarity analysis, introduced you to similarity groups, and then tried to introduce you to some discrete mathematics concepts but tried to go light on the math! After that, we identified several grouping tools that could be used to build your graphs before introducing you to hashing and fingerprinting tools. These tools can run algorithmic hash functions against a file-based payload or a network infrastructure to allow you to identify similarities between files or the uniqueness of an infrastructure target.

In the next chapter, we're going to move on to another phase of the intelligence cycle and focus on how to prepare, evaluate, and disseminate threat intelligence information.
