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.

The need and motivation for enrichment and analysis

For threat intelligence and security teams to successfully sift through the mountains of data that is often generated from an organizational environment, CTI and security functions need to examine enriched or contextualized data to action their workflows and understand the attack itself. This need is often achieved through an enrichment process, or the act of adding contextualization to specific data, making it more actionable.

Threat intelligence enrichment or analysis is the process of appending or enhancing the relevant context for data and, more specifically, threat intelligence data. Additionally, enrichment encompasses normalization processes for processing CTI data, such as deduplication. CTI functions aren't the sole beneficiary of enriched threat intelligence. Many additional teams outside of threat intelligence can benefit from enrichment, such as incident response, forensics, network security, Security Operation...
