04-08-09 U.S. Marines ban social networking use

The U.S Marine Corps is banning its troops from going onto Facebook,MySpace and other social network sites,citing a possible security risk.The corps issued an order Monday saying the ban is effective immediately on the Marine Corps computer network.It said the Internet has been used as a haven for malicious behavior,and said that using social sites can expose information to adversaries.The Associated Press has learned that the move is part of a larger Pentagon review.Deputy Defense Secretary William Lynn last week ordered a review of both the threats and benefits of using social networking — and asked it be done by the end of the month.The order does not affect Marines' private use of such networks on personal computers outside of their jobs
