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.

User authentication and authorization are two of the most critical aspects of computer security and privacy on the web. However, despite their importance, in practice, authentication and authorization are achieved through the use of decade-old techniques that are both often inconvenient for users and have been shown to be insecure against practical attackers. Many approaches have been proposed and attempted to improve and strengthen user authentication and authorization. Among them are authentication schemes that use hardware tokens, graphical passwords, one-time-passcode generators, and many more. Similarly, a number of approaches have been proposed to change how user authorization is performed. Unfortunately, none of the new approaches have been able to displace the traditional authentication and authorization strategies on the web. Meanwhile, attacks against user authentication and authorization continue to be rampant and are often (due to the lack of progress in practical defenses) successful. This dissertation examines the existing challenges to providing secure, private, and usable user authentication and authorization on the web. We begin by analyzing previous approaches with the goal of fundamentally understanding why and how previous solutions have not been adopted. Second, using this insight, we present three systems, each aiming to improve an aspect of user authentication and authorization on the web. Origin-Bound Certificates provide a deployable and secure building block for user credential transfer on the web. PhoneAuth uses Origin-Bound Certificates in order to allow users to securely authenticate to service providers in the face of strong attackers while maintaining the traditional username/password authentication model. Finally, Allowed Referrer Lists allow developers to easily protect applications against authorization vulnerabilities. We present the design, implementation, and evaluation for each of the three systems, demonstrating the feasibility of our approaches. Together, these works advance the state of the art in practical, usable and secure user authentication and authorization on the web. These systems demonstrate that through deep consideration of fundamental stakeholder values and careful engineering, it is possible to build systems that increase the security of user authentication and authorization without adversely impacting the user and developer experiences, while at the same time being deployable and practical.

As systems have become interconnected and more complicated, programmers needed ways to identify parties across multiple computers. One way to do this was for the parties that used applications on one computer to authenticate to the applications (and/or operating systems) that ran on the other computers. This mechanism is still widely used-for example, when logging on to a great number of Web sites. However, this approach becomes unmanageable when you have many co-operating systems (as is the case, for example, in the enterprise). Therefore, specialized services were invented that would register and authenticate users, and subsequently provide claims about them to interested applications. Some well-known examples are NTLM, Kerberos, Public Key Infrastructure (PKI), and the Security Assertion Markup Language (SAML). Most enterprise applications need some basic user security features. At a minimum, they need to authenticate their users, and many also need to authorize access to certain features so that only privileged users can get to them. Some apps must go further and audit what the user does. On Windows®, these features are built into the operating system and are usually quite easy to integrate into an application. By taking advantage of Windows integrated authentication, you don't have to invent your own authentication protocol or manage a user database. By using access control lists (ACLs), impersonation, and features such as groups, you can implement authorization with very little code. Indeed, this advice applies no matter which OS you are using. It's almost always a better idea to integrate closely with the security features in your OS rather than reinventing those features yourself. But what happens when you want to extend reach to users who don't happen to have Windows accounts? What about users who aren't running Windows at all? More and more applications need this type of reach, which seems to fly in the face of traditional advice. This book gives you enough information to evaluate claims-based identity as a possible option when you're planning a new application or making changes to an existing one. It is intended for any architect, developer, or information technology (IT) professional who designs, builds, or operates Web applications and services that require identity information about their users.

As an application designer or developer, imagine a world where you don't have to worry about authentication. Imagine instead that all requests to your application already include the information you need to make access control decisions and to personalize the application for the user. In this world, your applications can trust another system component to securely provide user information, such as the user's name or e-mail address, a manager's e-mail address, or even a purchasing authorization limit. The user's information always arrives in the same simple format, regardless of the authentication mechanism, whether it's Microsoft Windows integrated authentication, forms-based authentication in a Web browser, an X.509 client certificate, Windows Azure Access Control Service, or something more exotic. Even if someone in charge of your company's security policy changes how users authenticate, you still get the information, and it's always in the same format. This is the utopia of claims-based identity that A Guide to Claims-Based Identity and Access Control describes. As you'll see, claims provide an innovative approach for building applications that authenticate and authorize users. This book gives you enough information to evaluate claims-based identity as a possible option when you're planning a new application or making changes to an existing one. It is intended for any architect, developer, or information technology (IT) professional who designs, builds, or operates web applications, web services, or SharePoint applications that require identity information about their users.

Who Goes There?: Authentication Through the Lens of Privacy explores authentication technologies (passwords, PKI, biometrics, etc.) and their implications for the privacy of the individuals being authenticated. As authentication becomes ever more ubiquitous, understanding its interplay with privacy is vital. The report examines numerous concepts, including authentication, authorization, identification, privacy, and security. It provides a framework to guide thinking about these issues when deciding whether and how to use authentication in a particular context. The book explains how privacy is affected by system design decisions. It also describes government's unique role in authentication and what this means for how government can use authentication with minimal invasions of privacy. In addition, Who Goes There? outlines usability and security considerations and provides a primer on privacy law and policy.
