Pentagon considering to block Facebook, Twitter

Washington, Aug. 2 (ANI): The Pentagon is planning to ban Facebook, Twitter, and other social media at US Department of Defense sites.

The prospective ban isn't due to fears that troops might divulge secure information over the sites, or to worries about bad PR.

"The mechanisms for social networking were never designed for security and filtering. They make it way too easy for people with bad intentions to push malicious code to unsuspecting users. It's just a fact of life," Wired's Danger Room quoted a source at U.S. Strategic Command, as saying.

A recent example is how Guy Kawasaki's Twitter feed was hacked.

Somone broke in and posted a link to his feed, that took visitors to a site that installed a Trojan, which was used to take over users' devices.

The news comes just a day after PBS' MediaShift blog named chairman of the Joint Chiefs of Staff Mike Mullen as one of the best users of Twitter among public officials. (ANI)
