National Defense Magazine reports that "the Pentagon’s budget proposal for fiscal year 2015 includes $5.2 billion for cyber security. But when intelligence agencies are added to the mix, the amount nearly doubles, according to new estimates."
“'Cyber and business IT systems are among the few bright spots in the Defense Department’s investment budget plans,' says Douglas Berenson, budget analyst at The Avascent Group. The firm estimated that military spending on cyber security amounts to about $3.6 billion, and $6.3 billion goes to the intelligence community. That includes the CIA, Defense Intelligence Agency, National Reconnaissance Office, National Security Agency, National Geospatial-Intelligence Agency, Office of the Director of National Intelligence and other small civilian intelligence organization at the departments of State, Energy and Homeland Security."
"Agencies such as DIA, NRO, NSA, and NGA draw a significant share of their budgets from the Pentagon top line, Berenson said, so his figures are consistent with the Department of Defense estimate of $5.2 billion."
"Beyond these agencies, civilian federal cyber security spending is about $2.5 billion, which results in total federal government investment of about $12.4 billion."
