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.

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.

Reusable components and patterns for Ajax-driven applications Ajax is one of the latest and greatest ways to improve users’ online experience and create new and innovative web functionality. By allowing specific parts of a web page to be displayed without refreshing the entire page, Ajax significantly enhances the experience of web applications. It also lets web developers create intuitive and innovative interaction processes. Ajax for Web Application Developers provides the in-depth working knowledge of Ajax that web developers need to take their web applications to the next level. The book shows how to create an Ajax-driven web application from an object-oriented perspective, and it includes discussion of several useful Ajax design patterns. This detailed guide covers the creation of connections to a MySQL database with PHP 5 via a custom Ajax engine and shows how to gracefully format the response with CSS, JavaScript, and XHTML while keeping the data tightly secure. It also covers the use of four custom Ajax-enabled components in an application and how to create each of them from scratch. The final section of the book combines the individual code examples and techniques from earlier chapters of the book into one larger, Ajax-driven application—an internal web mail application that can be used in any user-based application, such as a community-based web application. Readers will learn not only how to create and use their own reusable Ajax components in this application but also how to connect their components to any future Ajax applications that they might build.

Ajax can bring many advantages to an existing web application without forcing you to redo the whole thing. This book explains how you can add Ajax to enhance, rather than replace, the way your application works. For instance, if you have a traditional web application based on submitting a form to update a table, you can enhance it by adding the capability to update the table with changes to the form fields, without actually having to submit the form. That's just one example. Adding Ajax is for those of you more interested in extending existing applications than in creating Rich Internet Applications (RIA). You already know the "business-side" of applications-web forms, server-side driven pages, and static content-and now you want to make your web pages livelier, more fun, and much more interactive. This book: Provides an overview of Ajax technologies, and the importance of developing a strategy for changing your site before you sit down to code Explains the heart and soul of Ajax: how to work with the XMLHttpRequest object Introduces and demonstrates several important Ajax libraries, including Prototype, script.aculo.us, rico, Mochikit Explores the interactive element that is Ajax, including how to work with events and event handlers that work across browsers Introduces the concept of web page as space, and covers three popular approaches to managing web space Explains how to make data updates, including adding new data, deleting, and making updates, all from within a single page Describes the effects Ajax has on the Web-breaking the back button, losing browser history, dynamic effects that disappear when the page is refreshed, and more Covers advanced CSS effects, including drag and drop "scroll bars", pagination, and the use of SVG and the Canvas object Explores mashups-Ajax's ability to combine data from different web services in any number of ways, directly in our web pages You don't need to start over to use Ajax. You can simply add to what you already have. This book explains how.

Cloud technologies have revolutionized the way we store information and perform various computing tasks. With the rise of this new technology, the ability to secure information stored on the cloud becomes a concern.
