Threat Modeling

The only security book to be chosen as a Dr. Dobbs Jolt Award Finalist since Bruce Schneier's Secrets and Lies and Applied Cryptography ! Adam Shostack is responsible for security development lifecycle threat modeling at Microsoft and is one of a handful of threat modeling experts in the world. Now, he is sharing his considerable expertise into this unique book. With pages of specific actionable advice, he details how to build better security into the design of systems, software, or services from the outset. You'll explore various threat modeling approaches, find out how to test your designs against threats, and learn effective ways to address threats that have been validated at Microsoft and other top companies. Systems security managers, you'll find tools and a framework for structured thinking about what can go wrong. Software developers, you'll appreciate the jargon-free and accessible introduction to this essential skill. Security professionals, you'll learn to discern changing threats and discover the easiest ways to adopt a structured approach to threat modeling. Provides a unique how-to for security and software developers who need to design secure products and systems and test their designs Explains how to threat model and explores various threat modeling approaches, such as asset-centric, attacker-centric and software-centric Provides effective approaches and techniques that have been proven at Microsoft and elsewhere Offers actionable how-to advice not tied to any specific software, operating system, or programming language Authored by a Microsoft professional who is one of the most prominent threat modeling experts in the world As more software is delivered on the Internet or operates on Internet-connected devices, the design of secure software is absolutely critical. Make sure you're ready with Threat Modeling: Designing for Security .

A major update to the definitive guide on threat modeling techniques for secure by design More than just a second edition, Threat Modeling: Designing for Security in an AI World thoroughly updates and expands on Adam Shostack's classic text and structured approach to analyzing and designing systems, software, and services for security flaws to address threats and technologies that didn’t exist when the first edition published. Most notably every reader will benefit from two new chapters covering using LLMs to threat model and exploring threats to LLMs, AIs, and ML Models themselves. There’s a new deep focus on agile and an expansion of who's involved in threat modeling, now including non-technical product owners. All told, half of this edition is completely new or heavily revised. Often called “the Bible of threat modeling,” Shostack’s approach has been adopted across industry, governments and is at the heart of OWASP’s threat modeling approaches. The first edition proved to be enduring and timeless, providing techniques that continued to work as technology and development paradigms shifted. This second edition presents an updated version of Shostack's Four-Question Framework that structures the threat modeling process from initial analysis through remediation. The specific actionable techniques proven from the first edition are updated to draw on thousands of conversations over the last decade. The guidance spans all technology. Readers gain structured methods to evaluate new additions to their technology, or business enterprise, and to select and prioritize effective defenses. You'll also discover: Increased discussion of cloud, IoT, and mobile A new chapter on boundaries, including how to identify and validate them across complex system architectures A new chapter on attack lifecycle models introduces the two most popular cyber kill chains, mapping attacker progression stages to identify optimal defensive intervention points A new framework for selecting and implementing effective defenses, spanning and clarifying choices from designs on the back of a napkin through systems that have been in operation since before the first edition Proven techniques for defensively managing remaining risk after threat identification, with structured and repeatable organizational approaches A cohesive scaling chapter transitions readers from the technical skills they acquire to the business challenges of scaling threat modeling Five legacy chapters and four appendices from the first edition are now available online at the book’s website, making room in the book for all of the new content while keeping cut material available for reference Written for engineers of all sorts, including security architects, security engineers, penetration testers, software developers building secure products, and IT administrators with security responsibilities, this Second Edition equips practitioners with structured, repeatable methods for identifying threats and designing defenses across any technology stack. The first edition showed how secure by design was a real possibility. The second shows even more clearly how to make it happen in your technology and products.

Threat modeling is one of the most essential--and most misunderstood--parts of the development lifecycle. Whether you're a security practitioner or a member of a development team, this book will help you gain a better understanding of how you can apply core threat modeling concepts to your practice to protect your systems against threats. Contrary to popular belief, threat modeling doesn't require advanced security knowledge to initiate or a Herculean effort to sustain. But it is critical for spotting and addressing potential concerns in a cost-effective way before the code's written--and before it's too late to find a solution. Authors Izar Tarandach and Matthew Coles walk you through various ways to approach and execute threat modeling in your organization. Explore fundamental properties and mechanisms for securing data and system functionality Understand the relationship between security, privacy, and safety Identify key characteristics for assessing system security Get an in-depth review of popular and specialized techniques for modeling and analyzing your systems View the future of threat modeling and Agile development methodologies, including DevOps automation Find answers to frequently asked questions, including how to avoid common threat modeling pitfalls
