Ajax Security by Billy Hoffman

By Billy Hoffman

The Hands-On, functional consultant to fighting Ajax-Related safety Vulnerabilities   increasingly more sites are being rewritten as Ajax functions; even conventional laptop software program is quickly relocating to the net through Ajax. yet, all too usually, this transition is being made with reckless forget for protection. If Ajax purposes aren’t designed and coded adequately, they are often prone to way more harmful safeguard vulnerabilities than traditional internet or laptop software program. Ajax builders desperately desire assistance on securing their purposes: wisdom that’s been nearly most unlikely to discover, before.             Ajax defense systematically debunks today’s most threatening myths approximately Ajax protection, illustrating key issues with targeted case experiences of tangible exploited Ajax vulnerabilities, starting from MySpace’s Samy malicious program to MacWorld’s convention code validator. much more vital, it gives you particular, up to the moment concepts for securing Ajax functions in every one significant internet programming language and surroundings, together with .NET, Java, Hypertext Preprocessor, or even Ruby on Rails. You’ll how you can:   ·        Mitigate special hazards linked to Ajax, together with overly granular internet prone, program keep watch over movement tampering, and manipulation of software good judgment ·        Write new Ajax code extra safely—and establish and fasten flaws in latest code ·        hinder rising Ajax-specific assaults, together with JavaScript hijacking and chronic garage robbery ·        keep away from assaults in line with XSS and SQL Injection—including a deadly SQL Injection version that may extract a complete backend database with simply requests ·        Leverage safety equipped into Ajax frameworks like Prototype, Dojo, and ASP.NET AJAX Extensions—and realize what you continue to needs to enforce by yourself ·        Create safer “mashup” purposes   Ajax safety might be an crucial source for builders coding or preserving Ajax purposes; architects and improvement managers making plans or designing new Ajax software program, and all software program defense pros, from QA experts to penetration testers.

Terrorism Informatics - Knowledge Management and Data Mining for Homeland Security

This e-book is not anything below an entire and complete survey of the state of the art of terrorism informatics. It covers the appliance of complex methodologies and data fusion and research. It additionally lays out concepts to obtain, combine, approach, learn, and deal with the variety of terrorism-related details for foreign and fatherland security-related functions.

Computer Network Security Theory and Practice

Buyers are mcreasmgly relymg on pubhc laptop networks to behavior bUSInessand look after family wishes. besides the fact that, public networks will be insecurebecause information saved in networked pcs or transmitted via networks canbe stolen, changed, or fabricated via malicious clients. hence, you will need to knowwhat security features can be found and the way to exploit them.

CompTIA A+ Complete Review Guide: Exam 220-701 / Exam 220-702

I've got in basic terms been utilizing the e-book for every week or so and feature discovered a few blunders actually. The e-book is old-fashioned on know-how, equivalent to, the Pentium four is the newest Intel processor mentioned and Rambus reminiscence is said as being 'relatively new', with out point out of DDR3 or four. the subject series follows the A+ pursuits, which does not lend itself to solid continuity.

Security for Web Services and Service-Oriented Architectures

Net providers in keeping with the eXtensible Markup Language (XML), the easy item entry Protocol (SOAP), and similar criteria, and deployed in Service-Oriented Architectures (SOA), are the major to Web-based interoperability for functions inside of and throughout enterprises. it can be crucial that the safety of prone and their interactions with clients is ensured if internet companies know-how is to dwell as much as its promise.

Sample text

Once a response is received from the asynchronous request, the data or page fragment contained in the response has to be inserted back into the current page. This is accomplished by making modifications to the DOM. getElementById to find the HTML span in which the time was displayed. The handleCurrentTimeChanged method then called additional DOM methods to create a text node if necessary and then modify its contents. This is nothing new or revolutionary; but the fact that the dynamic content can be refreshed from the server and not be included with the initial response makes all the difference.

Worse, the debitAccount function works the same way. It would be possible to completely wipe out all of the money in any user’s account. The existence of a server API also increases the attack surface of the application. An application’s attack surface is defined as all of the areas of the application that an attacker could potentially penetrate. The most commonly attacked portions of any Web application are its inputs. For traditional Web applications, these inputs include any form inputs, the query string, the HTTP request cookies, and headers, among others.

Complete page postbacks were still required to fetch new data. This made it impractical to use DHTML for applications like map and direction applications, because too much data—potentially gigabytes worth—needed to be downloaded to the client. This also made it impossible to use DHTML for applications that need to be continuously updated with fresh data, like stock tickers. It was not until the invention of XHR and Ajax that applications like these could be developed. AJAX:THE GOLDILOCKS OF ARCHITECTURE So, where does Ajax fit into the architecture scheme?
