Report: More companies ban social networks, Web 2.0 sites

A report released by MessageLabs, a UK-based security vendor, found that nearly 20 percent of organizations blocked social networking and dating sites in February due to concerns about employee productivity and malware. In addition, the number of websites blocked by filters was nearly 47 percent, which, according to MessageLabs, should spur IT departments to update their electronic use policies to reflect newer Web 2.0 technologies.”Organizations need to raise awareness about the risks of these sites,” says Paul Wood, a security analyst with MessageLabs. “Some of the policies are not up to date.”Wood says it wasn’t always clear how malware entered users’ computers or networks as a result of using social networks. In one example, however, he cited a case where a user visited a fake MySpace page where they were served up a pop-up add designed to look like a Microsoft software update. When the person clicked on the pop-up, they were taken to an illegitimate site that tried to install malware over JavaScript.
