For that it's worth, the DoD doesn't actually define "cyber warfare". In fact, in 2006 it depreciated the concept of "information warfare" (http://www.dtic.mil/doctrine/new_pubs/jp3_13.pdf). The closest concept the DoD has is "cyber operations" which are meant to "operate and defend the Global Information Grid" (http://www.dtic.mil/doctrine/new_pubs/jp1_02.pdf). Personally I don't think Scheiner focused enough on the fact that "cyber war" is essentially a media construction.
