The Hands-On, Practical Guide to Preventing Ajax-Related Security Vulnerabilities More and more Web sites are being rewritten as Ajax applications; even traditional desktop software is rapidly moving to the Web via Ajax. But, all too often, this transition is being made with reckless disregard for security. If Ajax applications aren’t designed and coded properly, they can be susceptible to far more dangerous security vulnerabilities than conventional Web or desktop software. Ajax developers desperately need guidance on securing their applications: knowledge that’s been virtually impossible to find, until now. Ajax Security systematically debunks today’s most dangerous myths about Ajax security, illustrating key points with detailed case studies of actual exploited Ajax vulnerabilities, ranging from MySpace’s Samy worm to MacWorld’s conference code validator. Even more important, it delivers specific, up-to-the-minute recommendations for securing Ajax applications in each major Web programming language and environment, including .NET, Java, PHP, and even Ruby on Rails. You’ll learn how to: · Mitigate unique risks associated with Ajax, including overly granular Web services, application control flow tampering, and manipulation of program logic · Write new Ajax code more safely—and identify and fix flaws in existing code · Prevent emerging Ajax-specific attacks, including JavaScript hijacking and persistent storage theft · Avoid attacks based on XSS and SQL Injection—including a dangerous SQL Injection variant that can extract an entire backend database with just two requests · Leverage security built into Ajax frameworks like Prototype, Dojo, and ASP.NET AJAX Extensions—and recognize what you still must implement on your own · Create more secure “mashup” applications Ajax Security will be an indispensable resource for developers coding or maintaining Ajax applications; architects and development managers planning or designing new Ajax software, and all software security professionals, from QA specialists to penetration testers.

Accompanied a CD-ROM containing tools, Flash-based demos, sample code, and more, a practical handbook introduces a wide variety of next generation security controls for Web 2.0 applications--including MySpace, GoogleMaps, and Wikipedia--discussing such topics as Ajax attack vectors and defense, hacking methodologies of SOAP, XML-RPC, and REST-based applications, reverse engineering for Flash and .NET applications, and more.

Ajax applications should be open yet secure. Far too often security is added as an afterthought. Potential flaws need to be identified and addressed right away. This book explores Ajax and web application security with an eye for dangerous gaps and offers ways that you can plug them before they become a problem. By making security part of the process from the start, you will learn how to build secure Ajax applications and discover how to respond quickly when attacks occur. Securing Ajax Applications succinctly explains that the same back-and-forth communications that make Ajax so responsive also gives invaders new opportunities to gather data, make creative new requests of your server, and interfere with the communications between you and your customers. This book presents basic security techniques and examines vulnerabilities with JavaScript, XML, JSON, Flash, and other technologies -- vital information that will ultimately save you time and money. Topics include: An overview of the evolving web platform, including APIs, feeds, web services and asynchronous messaging Web security basics, including common vulnerabilities, common cures, state management and session management How to secure web technologies, such as Ajax, JavaScript, Java applets, Active X controls, plug-ins, Flash and Flex How to protect your server, including front-line defense, dealing with application servers, PHP and scripting Vulnerabilities among web standards such as HTTP, XML, JSON, RSS, ATOM, REST, and XDOS How to secure web services, build secure APIs, and make open mashups secure Securing Ajax Applications takes on the challenges created by this new generation of web development, and demonstrates why web security isn't just for administrators and back-end programmers any more. It's also for web developers who accept the responsibility that comes with using the new wonders of the Web.

Every day, more users access services and electronically transmit information which is usually disseminated over insecure networks and processed by websites and databases, which lack proper security protection mechanisms and tools. This may have an impact on both the users’ trust as well as the reputation of the system’s stakeholders. Designing and implementing security enhanced systems is of vital importance. Therefore, this book aims to present a number of innovative security enhanced applications. It is titled “Security Enhanced Applications for Information Systems” and includes 11 chapters. This book is a quality guide for teaching purposes as well as for young researchers since it presents leading innovative contributions on security enhanced applications on various Information Systems. It involves cases based on the standalone, network and Cloud environments.

The Definitive Guide to Ajax Web Application Development Evolve from the click-and-wait programming pattern to the latest Web 2.0 paradigm using this comprehensive guide to Ajax. Written by Web development expert Thomas Powell, the book lays out every feature of Ajax alongside detailed explanations and real-world code examples. Ajax: The Complete Reference explains how to create and test Ajax-enabled Web applications using the XMLHttpRequest object as well as alternative JavaScript-based communication mechanisms. You'll explore a variety of sample applications featuring emerging user-interface conventions and build applications that address real-world networking and security issues. A robust communication library is developed throughout the book that enables you to architect flexible Ajax applications. The latest technologies such as Web services, Flash-Ajax integration, client-side templates, Comet, and Offline Access are also covered. Discover the future of Web development today! Work with traditional JavaScript communication approaches like iframes Explore all the quirks and details in the XMLHttpRequest object Handle disparate data formats, including XML, JSON, CSV, YAML, and more Deal with networking issues, including timeouts, retries, response ordering, and a variety of server and content errors Simplify JavaScript programming using open-source Ajax libraries like YUI Secure Ajax applications using authentication, obfuscation, and encryption Implement common Ajax UI patterns such as auto suggest, click-to-edit, and drag-and-drop Solve troubling Ajax architecture problems, including back button, history, and bookmarking issues Learn Ajax's role in Web 2.0 and Web services Explore push style communication using Comet and Flash Discover the future of offline Web application access and operation
