US Marines Ban Facebook and Twitter: Use of Social Network Sites

The U.S. Marine Corps made it official this week: Social networking sites such as Facebook and Twitter are banned from military networks.

This new administrative directive doesn't change very much but clarifies the use of social networks from a security perspective.

Marines have never been allowed to access non-official sites like Facebook, MySpace or Twitter from military networks because it is classed as improper use of government property.

In this new or revised directive, the Marines have simply put an official stamp on the ban. At the same time, they are also laying out the process to be followed by any Marine who wants to officially access such a site, as part of his or her job.

A Haven and Conduit for Adversaries
"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 directive noted.

Increased Threat
"The very nature of social networking sites, creates a larger threat, attack and exploitation window, exposes unnecessary information to adversaries and provides an easy conduit for information leakage."

Improper use of US equipment
The ban, however, is only for people using Marines' equipment and networks while they are working. Marines may still Twitter or post to Facebook on their own time and on their own computers but they should do so with a raised level of awareness.

The military isn't against using sites like Facebook and Twitter, said 1st Lt. Craig Thomas, a Pentagon-based spokesman for the Marine Corps.

Facebook, YouTube and Twitter
The U.S. Central Command has a Facebook page, a channel on YouTube and a Twitter account to get out information regarding operations news. The Army is using MySpace to recruit new soldiers and the U.S. Forces Afghanistan page on Facebook has more than 24,000 fans.
A Balanced Approach
"The Marine Corps has got to find a balance between security and letting Marines capitalise on the technology," Thomas said in a recent interview. "We don't want information leaks. We want to keep Marines focused on their mission at work and we also wanted to save critical bandwidth. We're trying to find the fine line."
Measured Progress
Thomas noted that 30 years ago, soldiers were warned about revealing too much information in letters home. Then 10 years ago, they were warned about how they used e-mail. Today, the focus is on social networks.

Tight Lips
"You can't have someone posting, 'Hey, we're leaving on this date and at this time,'" he added. "Believe me, the enemy is checking out what you guys are reporting and what service men and women are saying online.

The Marine Corps instills tight operational security. They need to be cognizant of what they're saying, whether verbally or what they're saying on social networking sites."
