Hacking Exposed Web 2.0
- Share to:
Web 2.0 is an industry buzz word that gets thrown around quite often. The term is often used for new web technology or comparison between products/services that extend from the initial web era to the existing one. For the purposes of this book, Web 2.0

addresses the new web technologies that are used to bring more interactivity to web applications, such as Google Maps and Live.com. Technologies such as Asynchronous JavaScript XML (AJAX), Cascading Style Sheets (CSS), Flash, XML, advanced usage of existing JavaScript, .Net, and ActiveX all fit under the Web 2.0 technology umbrella. While some of these technologies, such as ActiveX and Flash, have been around for awhile, organizations are just starting to use these technologies as core features of interactive web sites, rather than just visual effects. Additionally, Web 2.0 also includes a behavioral shift on the web, where users are encouraged to customize their own content on web applications rather than view static/ generic content supplied by an organization. For example, YouTube.com, MySpace.com, and blogging are a few examples of the Web 2.0 era, where these web applications are based on user supplied content. In the security world, any mention of a new technology often means that security is left out, forgotten, or simply marginalized. Unfortunately, this is also true about many Web 2.0 technologies. To complicate the issue further, the notion of “don’t ever trust user input” becomes increasingly difficult when an entire web application is based on user supplied input, ranging from HTML to Flash objects. In addition to the technology and behavior changes, Web 2.0 can also mean the shift from shrink-wrapped software to software as a service. During the early web era, downloading software from the web and running it on your server or desktop was the norm, ranging from Customer Relationship Management (CRM) applications to chat software. Downloading and managing software soon became a nightmare to organizations, as endless amount of servers, releases, and patches across hundreds of in-house applications drove IT costs through the roof.
