“It is about time that a book like The New School came along. The age of security as pure technology is long past, and modern practitioners need to understand the social and cognitive aspects of security if they are to be successful. Shostack and Stewart teach readers exactly what they need to know--I just wish I could have had it when I first started out.” --David Mortman, CSO-in-Residence Echelon One, former CSO Siebel Systems Why is information security so dysfunctional? Are you wasting the money you spend on security? This book shows how to spend it more effectively. How can you make more effective security decisions? This book explains why professionals have taken to studying economics, not cryptography--and why you should, too. And why security breach notices are the best thing to ever happen to information security. It’s about time someone asked the biggest, toughest questions about information security. Security experts Adam Shostack and Andrew Stewart don’t just answer those questions--they offer honest, deeply troubling answers. They explain why these critical problems exist and how to solve them. Drawing on powerful lessons from economics and other disciplines, Shostack and Stewart offer a new way forward. In clear and engaging prose, they shed new light on the critical challenges that are faced by the security field. Whether you’re a CIO, IT manager, or security specialist, this book will open your eyes to new ways of thinking about--and overcoming--your most pressing security challenges. The New School enables you to take control, while others struggle with non-stop crises. Better evidence for better decision-making Why the security data you have doesn’t support effective decision-making--and what to do about it Beyond security “silos”: getting the job done together Why it’s so hard to improve security in isolation--and how the entire industry can make it happen and evolve Amateurs study cryptography; professionals study economics What IT security leaders can and must learn from other scientific fields A bigger bang for every buck How to re-allocate your scarce resources where they’ll do the most good

The Workshop on the Economics of Information Security (WEIS) is the leading forum for interdisciplinary research and scholarship on information security and privacy, combining ideas, techniques, and expertise from the fields of economics, social science, business, law, policy, and computer science. In 2009, WEIS was held in London, at UCL, a constituent college of the University of London. Economics of Information Security and Privacy includes chapters presented at WEIS 2009, having been carefully reviewed by a program committee composed of leading researchers. Topics covered include identity theft, modeling uncertainty's effects, future directions in the economics of information security, economics of privacy, options, misaligned incentives in systems, cyber-insurance, and modeling security dynamics. Economics of Information Security and Privacy is designed for managers, policy makers, and researchers working in the related fields of economics of information security. Advanced-level students focusing on computer science, business management and economics will find this book valuable as a reference.

The Workshop on the Economics of Information Security (WEIS) is the leading forum for interdisciplinary scholarship on information security, combining expertise from the fields of economics, social science, business, law, policy and computer science. Prior workshops have explored the role of incentives between attackers and defenders, identified market failures dogging Internet security, and assessed investments in cyber-defense. Current contributions build on past efforts using empirical and analytic tools to not only understand threats, but also strengthen security through novel evaluations of available solutions. Economics of Information Security and Privacy III addresses the following questions: how should information risk be modeled given the constraints of rare incidence and high interdependence; how do individuals' and organizations' perceptions of privacy and security color their decision making; how can we move towards a more secure information infrastructure and code base while accounting for the incentives of stakeholders?

As threats to the security of information pervade the fabric of everyday life, A Vulnerable System describes how, even as the demand for information security increases, the needs of society are not being met. The result is that the confidentiality of our personal data, the integrity of our elections, and the stability of foreign relations between countries are increasingly at risk. Andrew J. Stewart convincingly shows that emergency software patches and new security products cannot provide the solution to threats such as computer hacking, viruses, software vulnerabilities, and electronic spying. Profound underlying structural problems must first be understood, confronted, and then addressed. A Vulnerable System delivers a long view of the history of information security, beginning with the creation of the first digital computers during the Cold War. From the key institutions of the so-called military industrial complex in the 1950s to Silicon Valley start-ups in the 2020s, the relentless pursuit of new technologies has come at great cost. The absence of knowledge regarding the history of information security has caused the lessons of the past to be forsaken for the novelty of the present, and has led us to be collectively unable to meet the needs of the current day. From the very beginning of the information age, claims of secure systems have been crushed by practical reality. The myriad risks to technology, Stewart reveals, cannot be addressed without first understanding how we arrived at this moment. A Vulnerable System is an enlightening and sobering history of a topic that affects crucial aspects of our lives.

This book is written for the first security hire in an organization, either an individual moving into this role from within the organization or hired into the role. More and more, organizations are realizing that information security requires a dedicated team with leadership distinct from information technology, and often the people who are placed into those positions have no idea where to start or how to prioritize. There are many issues competing for their attention, standards that say do this or do that, laws, regulations, customer demands, and no guidance on what is actually effective. This book offers guidance on approaches that work for how you prioritize and build a comprehensive information security program that protects your organization. While most books targeted at information security professionals explore specific subjects with deep expertise, this book explores the depth and breadth of the field. Instead of exploring a technology such as cloud security or a technique such as risk analysis, this book places those into the larger context of how to meet an organization's needs, how to prioritize, and what success looks like. Guides to the maturation of practice are offered, along with pointers for each topic on where to go for an in-depth exploration of each topic. Unlike more typical books on information security that advocate a single perspective, this book explores competing perspectives with an eye to providing the pros and cons of the different approaches and the implications of choices on implementation and on maturity, as often a choice on an approach needs to change as an organization grows and matures.

“A masterful guide to the interplay between cybersecurity and its societal, economic, and political impacts, equipping students with the critical thinking needed to navigate and influence security for our digital world.” —JOSIAH DYKSTRA, Trail of Bits “A comprehensive, multidisciplinary introduction to the technology and policy of cybersecurity. Start here if you are looking for an entry point to cyber.” —BRUCE SCHNEIER, author of A Hacker’s Mind: How the Powerful Bend Society’s Rules, and How to Bend Them Back The first-ever introduction to the full range of cybersecurity challenges Cybersecurity is crucial for preserving freedom in a connected world. Securing customer and business data, preventing election interference and the spread of disinformation, and understanding the vulnerabilities of key infrastructural systems are just a few of the areas in which cybersecurity professionals are indispensable.
