One of the many lures of Web 2.0 is that users do the heavy lifting, generating content and uploading it to Web sites. Enterprises are increasingly adopting Web 2.0 tools such as blogs, Wikis and RSS (define).
But are they adopting security best practices to keep pace? If not, the Secure Enterprise 2.0 Forum is offering a top 10 list of security issues related to the evolving technology.
The list includes threats specific to Web 2.0 technologies as well as older threats leveraging Web 2.0 type behavior such as content sharing, and community participation.
The Web 2.0-specific threats include cross-site scripting (XSS), various new types of injection attacks, and information leakage.
"In our experience, cross-site scripting is probably the most pernicious Web 2.0-related threat that companies should be made aware of," said David Lavenda, a vice president of marketing and product strategy at WorkLight, which sells security software for Web 2.0 environments. "This type of attack is hard to detect," he wrote in an e-mail. (The security company helped form the Secure Enterprise 2.0 Forum, which includes technology companies, research firms and security experts.)
Web 2.0 technologies are particularly susceptible to XSS attacks because of content sharing, Lavenda said.
Hackers often use XSS attacks on large sites to maximize the impact of the attacks. For example, a vulnerability that could have resulted in the theft of the identities of thousands of people was discovered on Yahoo's (NASDAQ: YHOO) HotJobs Web site in October.
User generated content's curse
User-generated content, which is a key feature of Web 2.0 technologies, also causes information leakage, the Forum said. This could lead an enterprise to host inappropriate content, which could impact its brand.
First, it screens all content that is uploaded to its site, Karmaloop CEO Greg Selkoe told Internetnews.com. Second, it leverages users by making its site very appealing and building communities among users. "We have people constantly viewing our site and if they see anything inappropriate they tell us and we take it down," Selkoe said.
