Mastering Cyber Intelligence

By: Jean Nestor M. Dahj

Overview of this book

The sophistication of cyber threats, such as ransomware, advanced phishing campaigns, zero-day vulnerability attacks, and advanced persistent threats (APTs), is pushing organizations and individuals to change strategies for reliable system protection. Cyber Threat Intelligence converts threat information into evidence-based intelligence that uncovers adversaries' intents, motives, and capabilities for effective defense against all kinds of threats. This book thoroughly covers the concepts and practices required to develop and drive threat intelligence programs, detailing the tasks involved in each step of the CTI lifecycle. You'll be able to plan a threat intelligence program by understanding and collecting the requirements, setting up the team, and exploring the intelligence frameworks. You'll also learn how and from where to collect intelligence data for your program, considering your organization level. With the help of practical examples, this book will help you get to grips with threat data processing and analysis. And finally, you'll be well-versed with writing tactical, technical, and strategic intelligence reports and sharing them with the community. By the end of this book, you'll have acquired the knowledge and skills required to drive threat intelligence operations from planning to dissemination phases, protect your organization, and help in critical defense decisions.

Open Source Intelligence Feeds (OSINT)

Threat intelligence sources can be expensive to acquire from private sources. For small and medium enterprises, spending thousands of dollars on TI data subscriptions could be unrealistic (financially disadvantageous). However, organizations can leverage public data from open sources to build intelligence. OSINT sources and feeds are a result of collective intelligence in a public fashion. Organizations, analysts, and researchers aggregate and structure their security output results and publish them as feeds for free. OSINT sources include overt feeds, search engines, usernames, email addresses, domains, social networks, IP and DNS lookups, and URLs. The list of OSINT sources is long, and the CTI team must be able to select the correct OSINT data for a specific intelligence program. Let's have a look at some benefits of OSINT.
