The U.S. Marine Corps has banned Twitter, Facebook, MySpace and other social media sites from its networks, effective immediately. "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," reads a Marine Corps order, issued Monday. "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."
