Effective immediately, the U.S. Marines have banned Twitter, Facebook, MySpace and all other social media sites from their networks.

According to an official order issued to the Marines, “These internet sites in general are a proven haven for malicious actors and content and are particularly high risk due to information exposure, user generated content and targeting by adversaries. The very nature of SNS [social network sites] creates a larger attack and exploitation window, exposes unnecessary information to adversaries and provides an easy conduit for information leakage that puts OPSEC [operational security], COMSEC [communications security], [and] personnel… at an elevated risk of compromise.”

The ban is currently slated to last a year, and was drawn up by U.S. Strategic Command due to network security concerns. But, if a Marine is able to provide a “mission critical need,” the sites could be temporarily unblocked. But, other than that, there will be no tweeting from the frontlines.
