Pentagon’s Cyber Mission Force Takes Shape

09.10.15 | 2 min read | Text by Steven Aftergood

The Department of Defense plans to complete the establishment of a new Cyber Mission Force made up of 133 teams of more than 6000 “cyber operators” by 2018, and it’s already nearly halfway there.

From FY2014-2018, DoD intends to spend $1.878 billion dollars to pay for the Cyber Missions Force consisting of approximately 6100 individuals in the four military services, DoD said in response to a question for the record that was published in a congressional hearing volume last month.

“This effort began in October 2013 and today we have 3100 personnel assigned to 58 of the 133 teams,” or nearly 50% of the intended capacity, DoD wrote in response to a question from Rep. Rick Larsen (D-WA) of the House Armed Services Committee. The response was included in the published record of a February 26, 2015 Committee hearing (page 67).

The DoD Cyber Mission Force was described in an April 2015 DoD Cyber Strategy and in April 2015 testimony by Assistant Secretary of Defense Eric Rosenbach:

“The Department of Defense has three primary missions in cyberspace: (1) defend DoD information networks to assure DoD missions, (2) defend the United States against cyberattacks of significant consequence, and (3) provide full-spectrum cyber options to support contingency plans and military operations,” Mr. Rosenbach said.

“To carry out these missions, we are building the Cyber Mission Force and equipping it with the appropriate tools and infrastructure to operate in cyberspace. Once fully manned, trained, and equipped in Fiscal Year 2018, these 133 teams will execute USCYBERCOM’s three primary missions with nearly 6,200 military and civilian personnel,” Mr. Rosenbach said at an April 14 hearing of the Senate Armed Services Committee.

The new Cyber Mission Force will naturally have both defensive and offensive characteristics.

“Congressman, we are building these cyber teams… in order to, one, protect ourselves from cyber attacks,” said Adm. Cecil D. Haney, commander of U.S. Strategic Command. “We are being probed on a daily basis by a variety of different actors.”

“The protection side is one thing,” said Rep. Larsen at the February hearing of the House Armed Services Committee. “What about the other side?”

“The other aspect of it, we are distributing these forces out to the various combatant commands so that they can be integrated into our overall joint military force capability,” Adm. Haney replied.

“Worldwide Cyber Threats” was the subject of an open hearing of the House Intelligence Committee on Thursday.

The foreign intrusions suffered by U.S. government and private networks have yielded some useful lessons, said Director of National Intelligence James R. Clapper.

“Of late, unauthorized disclosures and foreign defensive improvements have cost us some technical accesses, but we are also deriving valuable new insight from cyber security investigations of incidents caused by foreign actors and new means of aggregating and processing big data. Those avenues will help offset some more traditional collection modes that are obsolescent,” he told the Committee.
