Marine administrative message 458/09 says that social networking sites like Facebook, MySpace, and Twitter "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."
Social networking sites create vulnerabilities that can be exploited and may expose unnecessary information to adversaries, putting military personnel at increased risk of compromise, the directive says.
The ban does not cover access to social networking sites though non-military networks. And to correct any misapprehension about that point, the Marine Corps Office of Public Affairs subsequently issued a clarification.
Marine administrative message 458/09, titled "Immediate Ban Of Internet Social Networking Sites (SNS) On Marine Corps Enterprise Network (MCEN) NIPRNET," "does not limit Marines' access to social networking sites," the Marine Corps statement insists. "Even before this message, sites such as YouTube, Facebook, MySpace and Twitter could not be accessed by Marines using the Marine Corps Enterprise Network in accordance with Marine Corps and Department of the Navy policies."
The Marine Corps says that many military organizations currently make use of social media through alternative Internet service providers. The point of the directive is to establish a formal waiver process for those who require access to social networking sites through the MCEN.
The Marine Corps statement goes on to encourage military personnel to tell their stories using social media, but to do so using personal accounts and their own ISPs while keeping operational security requirements and standards of behavior in mind at all times.
The Marine Corps has an official presence on a variety of social media sites, including Facebook, Flickr, Twitter, and YouTube.
