The Senate Armed Services Committee is backing the creation of a "comprehensive cyber deterrence strategy," which involves dividing the responsibilities of the Defense Department's chief information officer and getting rid of the single position altogether, according to a summary of the fiscal 2018 National Defense Authorization Act.
The role of the CIO would be divided between the positions of the chief management officer and a new chief information warfare officer. The chief management officer would perform the business functions of the current CIO role.
Meanwhile, the new, presidentially appointed and Senate-confirmed position would take over the responsibilities relating to any aspect of the "information environment of the DoD," including the cyber domain, space systems, electromagnetic spectrums and electronic warfare.
The FY18 NDAA is currently being formulated by Congress.
