While the Pentagon is developing cyber arsenals, it is struggling to staff the newly operational Cyber Command and supporting service cyber organizations that will deploy against adversaries overseas.
If current cyber conflicts are any guide, future operations likely will require more than technical know-how -- they also could be just as reliant on the physical prowess of covert and clandestine operators capable of inserting computer code into networks at secure facilities. For example, the U.S.-Israeli-engineered Stuxnet computer virus that reportedly seized Iranian nuclear centrifuges was inserted manually through a jump drive, rather than propagated over the Internet from a safe location.
