Now a Days, cyber security is widely viewed as a matter of pressing national importance. Many elements of cyberspace are notoriously vulnerable to an expanding range of attacks by a spectrum of hackers, criminals, terrorists, and state actors. For example, government agencies and private-sector companies both large and small suffer from cyber thefts of sensitive information, cyber vandalism (e.g., defacing of Web sites), and denial-of-service attacks. The nation's critical infrastructure, including the electric power grid, air traffic control system, financial systems, and communication networks, depends extensively on information technology for its operation. National policy makers have become increasingly concerned that adversaries backed by considerable resources will attempt to exploit the cyber vulnerabilities in the critical infrastructure, thereby inflicting substantial harm on the nation. Numerous policy proposals have been advanced, and a number of bills have been introduced in Congress to tackle parts of the cyber security challenge. This book is designed to serve as the textbook for a semester course devoted to cyber security. It is focused on helping students acquired the skills sought in the professional workforce.

CYBER THREAT INTELLIGENCE"Martin takes a thorough and focused approach to the processes that rule threat intelligence, but he doesn't just cover gathering, processing and distributing intelligence. He explains why you should care who is trying to hack you, and what you can do about it when you know."--Simon Edwards, Security Testing Expert, CEO SE Labs Ltd., Chair AMTSOEffective introduction to cyber threat intelligence, supplemented with detailed case studies and after action reports of intelligence on real attacksCyber Threat Intelligence introduces the history, terminology, and techniques to be applied within cyber security, offering an overview of the current state of cyberattacks and stimulating readers to consider their own issues from a threat intelligence point of view. The author takes a systematic, system-agnostic, and holistic view to generating, collecting, and applying threat intelligence.The text covers the threat environment, malicious attacks, collecting, generating, and applying intelligence and attribution, as well as legal and ethical considerations. It ensures readers know what to look out for when considering a potential cyber attack and imparts how to prevent attacks early on, explaining how threat actors can exploit a system's vulnerabilities. It also includes analysis of large scale attacks such as WannaCry, NotPetya, Solar Winds, VPNFilter, and the Target breach, looking at the real intelligence that was available before and after the attack.Topics covered in Cyber Threat Intelligence include:* The constant change of the threat environment as capabilities, intent, opportunities, and defenses change and evolve* Different business models of threat actors, and how these dictate the choice of victims and the nature of their attacks* Planning and executing a threat intelligence programme to improve an organistation's cyber security posture* Techniques for attributing attacks and holding perpetrators to account for their actionsCyber Threat Intelligence describes the intelligence techniques and models used in cyber threat intelligence. It provides a survey of ideas, views and concepts, rather than offering a hands-on practical guide. It is intended for anyone who wishes to learn more about the domain, particularly if they wish to develop a career in intelligence, and as a reference for those already working in the area.Reviews:I really enjoyed this engaging book, which beautifully answered one of the first questions I had coming into the profession of cyber security: 'What is Cyber Threat Intelligence?' It progressively walked me through the world of cyber threat intelligence, peppered with rich content collected through years' of experience and knowledge. It is satisfyingly detailed to make it an interesting read for those already in cyber security wanting to learn more, but also caters to those who are just curious about the prevalent cyber threat and where it may be headed. One of the takeaways from this book for me is how finding threats is not the most important thing but how the effective communication of it is equally important so that it triggers appropriate actions at appropriate timing. Moreover, as a penetration tester, we are used to looking at the little details so it was refreshing and eye-opening to learn about the macro view on cyber threat landscape. Ryoko Amano, Penetration TesterCyber threats are a constant danger for companies in the private sector, which makes cyber threat intelligence an increasingly crucial tool for identifying security risks, developing proactive strategies, and responding swiftly to attacks. Martin Lee's new book is a comprehensive guide that takes the mystery out of using threat intelligence to strengthen a company's cyber defence. With a clear and concise explanation of the basics of threat intelligence, Martin provides a full picture of what's available and how to use it. Moreover, his book is packed with useful references and resources that will be invaluable for threat intelligence teams. Whether you're just starting in cybersecurity or a seasoned professional, this book is a must-have reference guide that will enhance your detection and mitigation of cyber threats. Gavin Reid, CISO VP Threat Intelligence at Human SecurityMartin Lee blends cyber threats, intel collection, attribution, and respective case studies in a compelling narrative. Lee does an excellent job of explaining complex concepts in a manner that is accessible to anyone wanting to develop a career in intelligence. What sets this book apart is the author's ability to collect related fundamentals and applications described in a pragmatic manner. Understandably, the book's challenge is non-disclosure of sensitive operational information. This is an excellent reference that I would highly recommend to cyber security professionals and academics wanting to deepen their domain expertise and broaden current knowledge. Threats indeed evolve and we must too. Dr Roland Padilla, FACS CP (Cyber Security), Senior Cyber Security Advisor - Defence Program (CISCO Systems), Army Officer (AUS DoD)An interesting and valuable contribution to the literature supporting the development of cyber security professional practice. This well researched and thoroughly referenced book provides both practitioners and those studying cyber threats with a sound basis for understanding the threat environment and the intelligence cycle required to understand and interpret existing and emerging threats. It is supported by relevant case studies of cyber security incidents enabling readers to contextualise the relationship between threat intelligence and incident response. Hugh Boyes, University of WarwickA valuable resource for anyone within the cyber security industry. It breaks down the concepts behind building an effective cyber threat intelligence practice by not only explaining the practical elements to gathering and sharing intelligence data, but the fundamentals behind why it's important and how to assess the usefulness of it. By also providing a detailed history of intelligence sharing across the ages with a rich set of examples, Martin is able to show the value of developing this side of cyber security that is often neglected. This book is equally accessible to those beginning their careers in cyber security as well as to those who have been in the industry for some time and wish to have a comprehensive reference. Stephan Freeman, Director, Axcelot LtdThis book is a wonderful read; what most impressed me was Martin's ability to provide a succinct history of threat intelligence in a coherent, easy to read manner. Citing numerous examples throughout the book, Martin allows the reader to understand what threat intelligence encompasses and provides guidance on industry best practices and insight into emerging threats which every organisation should be aware of. An incumbent read for any cybersecurity professional!

The Conficker worm infected its first computer in November 2008 and within a month had infiltrated 1.5 million computers in 195 countries. Banks, telecommunications companies, and critical government networks (including the British Parliament and the French and German military) were infected. No one had ever seen anything like it. By January 2009 the worm lay hidden in at least eight million computers and the botnet of linked computers that it had created was big enough that an attack might crash the world. Surprisingly, the U.S. government was only vaguely aware of the threat that Conficker posed, and the task of mounting resistance fell to disparate but gifted group of geeks, Internet entrepreneurs, and computer programmers. They formed what came to be called the Conficker Cabal, and began a tireless fight against the worm. But when Conficker's controllers became aware that their creation was beginning to encounter resistance, they began refining the worm's code to make it more difficult to trace and more powerful testing the Cabal's unity and resolve. Will the Cabal lock down the worm before it is too late? Game on. Worm reports on the fascinating battle between those determined to exploit the internet and those committed to protect it.

The Art of Cyber Security - A practical guide to winning the war on cyber crimeThis book is about cyber security, but it's also about so much more; it's about giving you the skills to think creatively about your role in the cyber security industry.In Part 1, the author discusses his thoughts on the cyber security industry and how those that operate within it should approach their role with the mindset of an artist.Part 2 explores the work of Sun Tzu's The Art of War.

Data and technology are so important to our lives, that protecting people who use technology is incredibly important. The professionals working to protect children, adults and corporations have a tough job, and this book celebrates their work while advocating ways for improving cyber security services and fighting cyber crime.This book will challenge your thinking and force you to approach cyber security and data protection from theoretical, philosophical, strategic, tactical and operational perspectives.

There is a threat lurking behind every online interaction that was first recognized nearly three decades ago, but very little has been done to fix it. It's only a matter of time before the unimaginable becomes reality -- life without the Internet. The race is on to get ahead of the danger and protect the Domain Name System (DNS) infrastructure of the Internet before the worst-case scenario ends the Internet as we know it.Based on decades of experience acquired by author Craig MacKinder as an information technology and cybersecurity expert, Cyberdefense: Domain Name Systems as the Next Public Utility is a multi-layered, comprehensive, extensively researched solution to the DNS threat. The way out of this imminent peril begins with securing online data by localizing queries to secure municipal DNS servers nationwide.The DNS is a fundamental and critical part of our global infrastructure, yet most users have no idea what it is, how it works, or how the DNS contributes to the overall stability of the Internet. This book explains the DNS in ways the average reader will easily digest and understand. The menace to Internet security is laid out and then confronted as the pros and cons of the existing partial solutions are explored. Finally, this book delivers an explanation of how local governments will provide universal Internet access to the public as the best mitigation for insecure DNS infrastructure.
