Web 2.0 is an umbrella term for a number of technologies that are enabling the "second" generation of the Internet. This second generation is heavily focused upon the goal of building a community of loyal users who collaboratively build and nurture a knowledge set around a product, a company, a belief system, a hobby, or some other common shared interest.

A Web 2.0 community is enabled through the use of collaborative applications and information gathering tools such as wikis, blogs, forums, syndication, and interactive voice and instant messaging. These applications are often built upon emerging development and messaging exchange standards such as RSS (Really Simple Syndication), XML (eXtensible Markup Language), AJAX (Asynchronous JavaScript and XML), and SIP (Session Initiation Protocol).

Web 2.0 communities and applications tend to generate large amounts of data with increasing frequency, and they require a greater leniency regarding the type of data allowed to be generated by users. This leniency can lead to increased Web application vulnerabilities, a higher volume of data transfer between the user and the application, and an increased danger of data loss in the event of a disaster.
