This book comprehensively reviews searchable encryption, which represents a series of research developments that directly enable search functionality over encrypted data. The book majorly covers: 1) the design and implementation of encrypted search algorithms, data structures, and systems that facilitate various forms of search over always-encrypted databases; 2) different threat models, assumptions, and the related security guarantees, when using searchable encryption in the real-world settings; and 3) latest efforts in building full-fledged encrypted database systems that draw insights from searchable encryption constructions. The book fits in the timely context, where the necessity of safeguarding important and sensitive data has been globally recognized. Traditional security measures, such as storing data behind network firewalls and layers of access control mechanisms to keep attackers out, are no longer sufficient to cope with the expanding landscape of surging cyber threats. There is an urgent call to keep sensitive data always encrypted to protect the data at rest, in transit, and in use. Doing so guarantees data confidentiality for owners, even if the data is out of their hands, e.g., hosted at in-the-cloud databases. The daunting challenge is how to perform computation over encrypted data. As we unfold in this book, searchable encryption, as a specific line of research in this broadly defined area, has received tremendous advancements over the past decades. This book is majorly oriented toward senior undergraduates, graduate students, and researchers, who want to work in the field and need extensive coverage of encrypted database research. It also targets security practitioners who want to make well-informed deployment choices of the latest advancements in searchable encryption for their targeted applications. Hopefully, this book will be beneficial in both regards.

This book tackles the problem of complexity within IT environments, i.e., "Cybercomplexity," which is generally recognized as a principal source of cybersecurity risk. The book first defines complexity and simplifies its analysis by assuming a probabilistic approach to security risk management. It then proposes a simple model of cybercomplexity that is based on Shannon entropy, a basic concept in information theory. The key drivers of cybercomplexity emerge from this model, where these drivers reveal the scale-dependence of cybersecurity risk and explain why macroscopic security controls are required to address cybersecurity risk on an enterprise scale. The significant operational implications of cybercomplexity are also discussed, thereby providing both a theoretical framework and a practical guide to addressing this longstanding problem in cybersecurity risk management.

Increasingly, identity theft is a fact of life. We might once have hoped to protect ourselves from hackers with airtight passwords and aggressive spam folders, and those are good ideas as far as they go. But the truth is, there are people out there - a lot of them - who treat stealing your identity as a full-time job.One such company is a nameless firm located in Russia, which has a trove of over a billion internet passwords. Another set up a website full of live streams of hacked web cameras, showing everything from people's offices and lobbies to the feeds from baby monitors. Even purchases made in person are still logged by retailers like Target, who are famously vulnerable to hackers. Adam Levin, a longtime consumer advocate and identity fraud expert, is your guide to this brave new world. By telling memorable stories and extracting the relevant lessons, he offers a strategy for dealing with these risks. You may not be able to prevent identity theft, but you certainly shouldn't wait until it happens to take action. Levin's approach is defined by the three M's: minimizing risk, monitoring your identity, and managing the damage. The book is also organized around the different problems caused by identity theft: financial, criminal, medical, familial, etc., enabling readers to dip into the sections most relevant to them. Swiped is a practical, lively book that is essential to surviving the ever-changing world of online security. It is invaluable not only for preventing problems but helping cope when they arrive.
