In the ever-evolving world of cybersecurity, the need for robust and proactive threat intelligence has never been more critical. This book is designed to arm you with the essential knowledge and tools required to establish a world-class cyber threat intelligence (CTI) capability. Authored by Crawford Thomas, a seasoned expert with over two decades of frontline experience in military intelligence and cyber threat intelligence within the financial sector, this guide is not just theoretical—it's a distillation of hard-earned, practical wisdom. This book is not a typical consultation manual filled with checkboxes and generic advice. Instead, it draws from the real-world experiences of a practitioner who has navigated the complexities of regulatory pressures and excelled in environments that demand nothing less than excellence. Notably, during a recent CBEST testing, Thomas’s leadership and the performance of his CTI team were described as "formidable." This recognition underscores the level of expertise and effectiveness you can expect to learn from. You are invited on a comprehensive journey through the critical stages of building a CTI function: from developing a strategic vision, formulating prioritized intelligence requirements, and selecting the right vendors, to mastering the nuances of intelligence reporting. This book is designed to guide you in creating a CTI capability that not only protects your business, but also enhances its efficacy and fosters an environment of reliability and trust—both internally and externally. The necessity for this book stems from the current cybersecurity landscape where businesses face an increasing barrage of threats. They require impeccable IT security across all platforms, often taking on risks that stretch beyond their risk appetite. Email systems, provided ubiquitously by major vendors, remain a prime target despite advanced security measures. Meanwhile, the rise of Ransomware as a Service has given a new edge to this already formidable threat, turning organizations into unwitting participants in attacks aimed at third-party applications.  What You Will Learn:How to build a world leading cyber threat intelligence capability that is threat vector focused.
