Human factors and usability issues have traditionally played a limited role in security research and secure systems development. Security experts have largely ignored usability issues--both because they often failed to recognize the importance of human factors and because they lacked the expertise to address them.
But there is a growing recognition that today's security problems can be solved only by addressing issues of usability and human factors. Increasingly, well-publicized security breaches are attributed to human errors that might have been prevented through more usable software. Indeed, the world's future cyber-security depends upon the deployment of security technology that can be broadly used by untrained computer users.
Still, many people believe there is an inherent tradeoff between computer security and usability. It's true that a computer without passwords is usable, but not very secure. A computer that makes you authenticate every five minutes with a password and a fresh drop of blood might be very secure, but nobody would use it. Clearly, people need computers, and if they can't use one that's secure, they'll use one that isn't. Unfortunately, unsecured systems aren't usable for long, either. They get hacked, compromised, and otherwise rendered useless.
There is increasing agreement that we need to design secure systems that people can actually use, but less agreement about how to reach this goal. Security & Usability is the first book-length work describing the current state of the art in this emerging field. Edited by security experts Dr. Lorrie Faith Cranor and Dr. Simson Garfinkel, and authored by cutting-edge security and human-computer interaction (HCI) researchers world-wide, this volume is expected to become both a classic reference and an inspiration for future research.
Security & Usability groups 34 essays into six parts:
- Realigning Usability and Security---with careful attention to user-centered design principles, security and usability can be synergistic.
- Authentication Mechanisms-- techniques for identifying and authenticating computer users.
- Secure Systems--how system software can deliver or destroy a secure user experience.
- Privacy and Anonymity Systems--methods for allowing people to control the release of personal information.
- Commercializing Usability: The Vendor Perspective--specific experiences of security and software vendors (e.g., IBM, Microsoft, Lotus, Firefox, and Zone Labs) in addressing usability.
- The Classics--groundbreaking papers that sparked the field of security and usability.
This book is expected to start an avalanche of discussion, new ideas, and further advances in this important field.
Dr. Lorrie Faith Cranor is a principal technical staff member in the Secure Systems Research Department at AT&T Labs-Research Shannon Laboratory in Florham Park, New Jersey. She is chair of the Platform for Privacy Preferences Project (P3P) Specification Working Group at the World Wide Web Consortium. Her research has focused on a variety of areas where technology and policy issues interact, including online privacy, electronic voting, and spam. Dr. Cranor plays the tenor saxophone in the Chatham Community Band. She spends most of her free time with her husband, Chuck, and her son, Shane, but sometimes she finds time to design and create quilts. Simson Garfinkel, CISSP, is a journalist, entrepreneur, and international authority on computer security. Garfinkel is chief technology officer at Sandstorm Enterprises, a Boston-based firm that develops state-of-the-art computer security tools. Garfinkel is also a columnist for Technology Review Magazine and has written for more than 50 publications, including Computerworld, Forbes, and The New York Times. He is also the author of Database Nation; Web Security, Privacy, and Commerce; PGP: Pretty Good Privacy; and seven other books. Garfinkel earned a master's degree in journalism at Columbia University in 1988 and holds three undergraduate degrees from MIT. He is currently working on his doctorate at MIT's Laboratory for Computer Science.
