For Marines stationed abroad, social networks are a handy way to keep in touch with family and friends back home. But a new order today bans the use of sites such as Twitter and Facebook, which the Marine Corps says could be used to spread "malicious" content. "The very nature of [social networks] creates a larger attack and exploitation window, exposes unnecessary information to adversaries, and provides an easy conduit for information leakage," the order reads.
The directive does not affect Marines' use of private computers – only the machines that are connected to the central Marine Corps grid. According to the Associated Press, "the reason for the new ban was to set up a special waiver system that [governs] access for Marines who need to reach the sites as part of their duties." Deputy Defense Secretary William Lynn, the AP reports, has ordered a review of the threats of use of social networks and blogging platforms.
