There has been roughly 15 years of research into approaches for aligning research in Human Computer Interaction with computer Security, more colloquially known as ``usable security.'' Although usability and security were once thought to be inherently antagonistic, today there is wide consensus that systems that are not usable will inevitably suffer security failures when they are deployed into the real world. Only by simultaneously addressing both usability and security concerns will we be able to build systems that are truly secure. This book presents the historical context of the work to date on usable security and privacy, creates a taxonomy for organizing that work, outlines current research objectives, presents lessons learned, and makes suggestions for future research.

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-computerinteraction (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.

Everyone expects the products and services they use to be secure, but 'building security in' at the earliest stages of a system's design also means designing for use as well. Software that is unusable to end-users and unwieldy to developers and administrators may be insecure as errors and violations may expose exploitable vulnerabilities. This book shows how practitioners and researchers can build both security and usability into the design of systems. It introduces the IRIS framework and the open source CAIRIS platform that can guide the specification of secure and usable software. It also illustrates how IRIS and CAIRIS can complement techniques from User Experience, Security Engineering and Innovation & Entrepreneurship in ways that allow security to be addressed at different stages of the software lifecycle without disruption. Real-world examples are provided of the techniques and processes illustrated in this book, making this text a resource for practitioners, researchers, educators, and students.

This qualitative study builds on prior literature establishing significant correlations between behavioral compliance with information security mechanisms among novice computer users and their mental models relating to information security. The study examines the effectiveness of a usability-designed methodology to increase user compliance with established secure computing best practices by aligning users; mental models with more accurate conceptual representations of risk parameters. In the study, a small group of non-expert users were assessed using survey, contextual inquiry, and simple interview techniques to determine (a) personal computing requirements and preferences, (b) levels of information security awareness, and (c) levels of motivation to maintain a secure computing environment. "Usable, secure personal computing environments; (USPCEs) were then designed to the particulars of each user's computing profile. Following technical deployment and user orientation, participants conducted routine computing in their individualized usable, secure personal computing environments, and were then queried for their reactions. Users were evaluated in security awareness assessments before and after USPCE implementation. The study found that participants' mental models of security risk factors as expressed in the second security awareness assessment were more accurate than in the first. Participants are also self-reported higher levels of compliance with information security best practices than prior to implementation of the individually designed USPCEs. A particular outcome of this approach was that the scope of user assessments and USPCE interventions included personal computing on mobile, portable, as well as conventional computing devices. As such, the approach is particularly adopted to the usable security requirements of ubiquitous computing.

Text passwords are still the primary authentication mechanism for computers and online systems world-wide. Prior work indicates that they would likely persist in the foreseeable future, despite alternative proposals. Therefore, it is crucial to examine the open issues in text passwords. In addition, instead of replacing text passwords entirely, alternatives could be proposed for use under specific context. Under such premises, this thesis focused on (1) to demonstrate the field performance of a serious alternative method for mobile authentication and (2) to propose a systematic experiment design to study password memorability. Designed to be used for desktop computers originally, text passwords are not suitable for modern platforms such as mobile devices. Using text passwords on mobile devices is a drastically different experience, because of the different form factor and context. From a between-group lab study comparing passwords usage on different devices, we learned that the form factor alone already has an effect on aspects of passwords such as the amount of lowercase letters used per password. Meanwhile, recent studies suggest that free-form gesture passwords are a viable alternative as an authentication method on touchscreen devices. However, little is known about the actual advantages they carry when deployed for everyday mobile use. We performed the first field study (N=91) of mobile authentication using free-form gestures, with text passwords being the baseline. Motivated by Experience Sampling Method (ESM), our study design aimed at increasing ecological validity while still maintaining control of the experiment. We found that, with gesture passwords, participants gen- erated new passwords and authenticated faster with comparable memorability, while being more willing to retry. Our analysis of the gesture password dataset indicated the choice of gestures varied across categories. Our findings demonstrated gesture passwords are a serious alternative for mobile context. A major struggle people have with text passwords is to create ones that are both secure and memorable. Although there has been research on measuring password security, we have yet to systematically discover the factors to affect password memorability. By combining existing memory findings and password specific contexts, we proposed a field experiment design centering on two major factors that affect password memorability: log-in frequency and password condition. Log-in frequency defines the frequency of log-in tasks, and password condition defines the condition each password was created. The result of the experiment revealed that potential effects of our factors exist and pointed out directions for future studies.

Despite many advances, security and privacy often remain too complex for individuals or enterprises to manage effectively or to use conveniently. Security is hard for users, administrators, and developers to understand, making it all too easy to use, configure, or operate systems in ways that are inadvertently insecure. Moreover, security and privacy technologies originally were developed in a context in which system administrators had primary responsibility for security and privacy protections and in which the users tended to be sophisticated. Today, the user base is much wider--including the vast majority of employees in many organizations and a large fraction of households--but the basic models for security and privacy are essentially unchanged. Security features can be clumsy and awkward to use and can present significant obstacles to getting work done. As a result, cybersecurity measures are all too often disabled or bypassed by the users they are intended to protect. Similarly, when security gets in the way of functionality, designers and administrators deemphasize it. The result is that end users often engage in actions, knowingly or unknowingly, that compromise the security of computer systems or contribute to the unwanted release of personal or other confidential information. Toward Better Usability, Security, and Privacy of Information Technology discusses computer system security and privacy, their relationship to usability, and research at their intersection.

Evaluations of the usability and security of alphanumeric passwords and Personal Identification Numbers (PINs) have shown that users cannot remember credentials considered to be secure. However, the continued reliance upon these methods of user authentication has placed end-users and system designers in a coevolutionary struggle, with each defending competing concerns of usability and security. Graphical passwords have been proposed as an alternative, and their use is supported by cognitive theories such as the picture superiority effect which suggest that pictures, rather than words or numbers, could provide a stronger foundation upon which to design usable and secure knowledge-based authentication. Indeed, early usability studies of novel systems harnessing this effect appear to show promise, however, the uptake of graphical passwords in real-world systems is low. This inertia is likely related to uncertainty regarding the challenges that novel systems might bring to the already delicate interplay between usability and security; particularly the new challenges faced in scaffolding user behaviours that comply with context-specific security policies, uncertainty regarding the nature of new socio-technical attacks, and the impact of images themselves upon usability and security. In this thesis we present a number of case studies incorporating new designs, empirical methods and results, that begin to explore these aspects of representative graphical password systems. Specifically, we explore: (i) how we can implicitly support security-focused behaviours such as choosing high entropy graphical passwords and defending against observation attack; (ii) how to capture the likely extent of insecure behaviour in the social domain such as graphical password sharing and observation attack; and (iii) how through the selection of appropriate properties of the images themselves we can provide security and usability benefits. In doing so, we gen- erate new insights into the potential of graphical passwords to provide usable, secure and deployable user authentication.
