Download or read book Supporting Users in Password Authentication with Persuasive Design written by Tobias Seitz and published by Tobias Seitz. This book was released on 2018-08-03 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activities like text-editing, watching movies, or managing personal finances are all accomplished with web-based solutions nowadays. The providers need to ensure security and privacy of user data. To that end, passwords are still the most common authentication method on the web. They are inexpensive and easy to implement. Users are largely accustomed to this kind of authentication but passwords represent a considerable nuisance, because they are tedious to create, remember, and maintain. In many cases, usability issues turn into security problems, because users try to work around the challenges and create easily predictable credentials. Often, they reuse their passwords for many purposes, which aggravates the risk of identity theft. There have been numerous attempts to remove the root of the problem and replace passwords, e.g., through biometrics. However, no other authentication strategy can fully replace them, so passwords will probably stay a go-to authentication method for the foreseeable future. Researchers and practitioners have thus aimed to improve users' situation in various ways. There are two main lines of research on helping users create both usable and secure passwords. On the one hand, password policies have a notable impact on password practices, because they enforce certain characteristics. However, enforcement reduces users' autonomy and often causes frustration if the requirements are poorly communicated or overly complex. On the other hand, user-centered designs have been proposed: Assistance and persuasion are typically more user-friendly but their influence is often limited. In this thesis, we explore potential reasons for the inefficacy of certain persuasion strategies. From the gained knowledge, we derive novel persuasive design elements to support users in password authentication. The exploration of contextual factors in password practices is based on four projects that reveal both psychological aspects and real-world constraints. Here, we investigate how mental models of password strength and password managers can provide important pointers towards the design of persuasive interventions. Moreover, the associations between personality traits and password practices are evaluated in three user studies. A meticulous audit of real-world password policies shows the constraints for selection and reuse practices. Based on the review of context factors, we then extend the design space of persuasive password support with three projects. We first depict the explicit and implicit user needs in password support. Second, we craft and evaluate a choice architecture that illustrates how a phenomenon from marketing psychology can provide new insights into the design of nudging strategies. Third, we tried to empower users to create memorable passwords with emojis. The results show the challenges and potentials of emoji-passwords on different platforms. Finally, the thesis presents a framework for the persuasive design of password support. It aims to structure the required activities during the entire process. This enables researchers and practitioners to craft novel systems that go beyond traditional paradigms, which is illustrated by a design exercise.

Download or read book Mobile Applications written by Tejinder S. Randhawa and published by Springer Nature. This book was released on 2022-08-17 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Android as a reference, this book teaches the development of mobile apps designed to be responsive, trustworthy and robust, and optimized for maintainability. As the share of mission-critical mobile apps continues to increase in the ever-expanding mobile app ecosystem, it has become imperative that processes and procedures to assure their reliance are developed and included in the software life cycle at opportune times. Memory, CPU, battery life and screen size limitations of smartphones coupled with volatility associated with mobile environments underlines that the quality assurance strategies that proved to be successful for desktop applications may no longer be effective in mobile apps. To that effect, this book lays a foundation upon which quality assurance processes and procedures for mobile apps could be devised. This foundation is composed of analytical models, experimental test-beds and software solutions. Analytical models proposed in the literature to predict software quality are studied and adapted for mobile apps. The efficacy of these analytical models in prejudging the operations of mobile apps under design and development is evaluated. A comprehensive test suite is presented that empirically assesses a mobile app’s compliance to its quality expectations. Test procedures to measure quality attributes such as maintainability, usability, performance, scalability, reliability, availability and security, are detailed. Utilization of test tools provided in Android Studio as well as third-party vendors in constructing the corresponding test-beds is highlighted. An in-depth exploration of utilities, services and frameworks available on Android is conducted, and the results of their parametrization observed through experimentation to construct quality assurance solutions are presented. Experimental development of some example mobile apps is conducted to gauge adoption of process models and determine favorable opportunities for integrating the quality assurance processes and procedures in the mobile app life cycle. The role of automation in testing, integration, deployment and configuration management is demonstrated to offset cost overheads of integrating quality assurance process in the life cycle of mobile apps.

Download or read book Openid Connect written by Matthias Biehl and published by Createspace Independent Publishing Platform. This book was released on 2019-02-03 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signup and login with a Google, Yahoo, or Microsoft account can be found in more and more web and mobile apps. One login used by many, freeing the end-user from the burden of managing many accounts and passwords. Signup and login to a new app become so smooth and convenient, that end-users are much more likely to try a new app. For us developers of web and mobile apps, these signup and login features are attractive, too: we do not need to manage user credentials, and we get a higher conversion rate resulting in more new customers. In effect, this means cutting costs and increasing the number of new customers for our apps.So how does this feature "Signup and login with Google, Yahoo, or Microsoft" work? It is realized with OpenID Connect, a standardized protocol for sharing end-user data in a secure and controlled manner. Exploring how OpenID Connect works, so we as developers can enjoy its benefits is the subject of this book. This book explains the overall concept of OpenID Connect, so we understand who the actors are, which endpoints and tokens are involved and how these elements interact in so-called flows. These flows tend to get confusing, so we visualize these flows as sequence diagrams, and show how to choose the flow that is appropriate for a given scenario. Using examples, we explore how the tokens are constructed, signed and encrypted with JWT, JWS, and JWE. This is not a programming book, don't expect implementations with a specific programming language or library. Instead, we focus on understanding OpenID Connect on a conceptual level, so we can design and architect apps that work with OpenID Connect. And OpenID Connect is the standard behind creating smooth login and signup experiences, increasing the customer signup rate, and creating highly converting apps.

Download or read book Authentication and Authorization on the Web written by Nigel Chapman and published by . This book was released on 2012-10 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: A short book in the "Web Security Topics" series for Web developers, by the well-known authors Nigel and Jenny Chapman. Web applications manipulate resources in response to requests from users. It is often necessary to determine whether a requested operation should be allowed for the user who sent the request. This process of authorization - that is, deciding whether an application should be allowed to carry.out the operation which a request from a particular user or program calls for - depends on, but is separate from, the process of authentication. Authentication means determining the identity of the user or program sending the request. This is usually done by maintaining user accounts, protected by passwords, and by requiring users to log in. Written for professional and student Web developers, this book provides a clear and practical description of authentication and authorization for Web sites. Secure methods of storing users' account details are described, with special emphasis on the secure storage of passwords. The authors explain different methods of authentication, and techniques for applying authorization to requests from authenticated users. A simple application, written in JavaScript and built on the Express framework, is developed throughout the book to demonstrate the principles. The source code is provided via the companion site websecuritytopics.info. Topics covered include hashing and salting passwords for secure storage, using CAPTCHAs to prevent the creation of bogus accounts, resetting passwords, session-based authentication and attacks against sessions, HTTP authentication, OpenId, authorization based on user accounts, role-based authorization, and OAuth. Notes on relevant topics in cryptography are also included. Clear key points provide useful summaries at the end of each section, and technical terms are defined in a 16-page glossary.

Download or read book Web Authentication using Third Parties in Untrusted Environments written by Anna Vapen and published by Linköping University Electronic Press. This book was released on 2016-08-22 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing personalization of the Web, many websites allow users to create their own personal accounts. This has resulted in Web users often having many accounts on different websites, to which they need to authenticate in order to gain access. Unfortunately, there are several security problems connected to the use and re-use of passwords, the most prevalent authentication method currently in use, including eavesdropping and replay attacks. Several alternative methods have been proposed to address these shortcomings, including the use of hardware authentication devices. However, these more secure authentication methods are often not adapted for mobile Web users who use different devices in different places and in untrusted environments, such as public Wi-Fi networks, to access their accounts. We have designed a method for comparing, evaluating and designing authentication solutions suitable for mobile users and untrusted environments. Our method leverages the fact that mobile users often bring their own cell phones, and also takes into account different levels of security adapted for different services on the Web. Another important trend in the authentication landscape is that an increasing number of websites use third-party authentication. This is a solution where users have an account on a single system, the identity provider, and this one account can then be used with multiple other websites. In addition to requiring fewer passwords, these services can also in some cases implement authentication with higher security than passwords can provide. How websites select their third-party identity providers has privacy and security implications for end users. To better understand the security and privacy risks with these services, we present a data collection methodology that we have used to identify and capture third-party authentication usage on the Web. We have also characterized the third-party authentication landscape based on our collected data, outlining which types of third-parties are used by which types of sites, and how usage differs across the world. Using a combination of large-scale crawling, longitudinal manual testing, and in-depth login tests, our characterization and analysis has also allowed us to discover interesting structural properties of the landscape, differences in the cross-site relationships, and how the use of third-party authentication is changing over time. Finally, we have also outlined what information is shared between websites in third-party authentication, dened risk classes based on shared data, and proled privacy leakage risks associated with websites and their identity providers sharing data with each other. Our ndings show how websites can strengthen the privacy of their users based on how these websites select and combine their third-parties and the data they allow to be shared.

Download or read book BDSLCCI written by Dr. Shekhar Pawar, Poonam Shekhar Pawar and published by Notion Press. This book was released on 2023-08-18 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is especially important for top management and other stakeholders of small and medium companies (SME or SMB). Small and medium companies are the major contributors to overall employment, the GDP of most countries, and the global economy. Recent cyberattack statistics show that SMEs are always a target for cybercriminals, posing a direct threat to the global economy if they are not protected. To understand the current scenarios in the SME segment, Dr. Shekhar Pawar conducted research to get insights into the current cybersecurity posture of each participant SME as well as the problems faced by businesses in adopting cybersecurity controls. The input from many SMEs working in different domains and from different countries helped Dr. Pawar understand the gaps that are helping cyberattacks to be successful. The top three issues identified during research were a lack of required financial investment, a lack of skilled resources, and not getting visibility into how investment in cybersecurity implementation will contribute to business growth. To address these problems, Dr. Pawar invented a new cybersecurity framework known as Business Domain Specific Least Cybersecurity Controls Implementation (BDSLCCI). It provides a tailored list of cybersecurity controls depending on the business domain of the SME, reducing costs and resources while providing a return on investment for businesses. BDSLCCI is now an AI ML-driven web platform with a few useful tools to assist companies in easily adopting it.
