Cyberwarfare (Score 1)

It is a given that wars are won and lost by hitting an enemies logistical supply chains and disrupting their economic infrastructure to produce goods and services for both units in the field as well as support units. It is also a given that battles are won and lost due to breaking an enemie's codes and reading their operational transmissions (for example: Ultra and Magic), or by inserting false information into their operational networks, and perhaps analyzing signals traffic. (e.g. Battle of Midway, Battle of the Atlantic, etc) I would like to know, what the Army is doing to secure our IT systems and networks which deal with Supply Chain Management for our Forces as well as securing our critical IT infrastructures (Power Grids, Financial Markets, Medical Databases, Petroleum Industries, Shipping Company Networks, etc) necessary to keep our Industrial Complex running in order to support our troops. Perhaps the simplest solution is simply to "pull the plug" and take the US or other countries Offline by hitting their undersea cables for communicating with other nations. Or perhaps going on the offensive and hitting their systems and thus disrupting their IT infrastructure. Comments?
