Department of Homeland Security Cybersecurity Strategy Act of 2015

Department of Homeland Security Cybersecurity Strategy Act of 2015 This bill requires the Department of Homeland Security (DHS) to develop a cybersecurity strategy that includes: (1) strategic and operational goals and priorities to execute the full range of DHS's cybersecurity responsibilities; and (2) information on programs, policies, and activities in furtherance of the cybersecurity functions of the national cybersecurity and communications integration center (NCCIC), investigations capabilities, research and development, and engagement with international partners. The strategy must include the roles and responsibilities of DHS components and offices. Congressional authorization is required for any reorganization of such components or offices. For purposes of the NCCIC, the bill redefines "incident" to include occurrences that actually or imminently jeopardize, without lawful authority, an information system, thereby replacing a standard that currently includes a violation or imminent threat of violation of law, security policies, security procedures, or acceptable use policies.
