DoD recognizes the risk posed by emerging threats to our mission critical cyber-dependent FRCS and capabilities that require constant, unwavering vigilance to ensure availability to perform under all conditions. Consequently, DoD pursues relevant protection approaches that enable a unity of security efforts to secure our networks, facilities, personnel, and operations while minimizing insider threats. FRCS Cybersecurity enables resiliency of essential utilities, environmental temperature and humidity control, fire protection, physical access control, and other key services that almost all other Department of Defense (DoD) Information Technology (IT) rely upon for mission assurance. The EI&E community is responsible for ensuring that FRCS and networks are both physically and logically cyber secure throughout their lifecycle, to include design, construction, operation, maintenance, and decommissioning. The EI&E community must also ensure an adequately trained and cyber-aware workforce is established and maintained, and leadership is informed and engaged on CS Cybersecurity status. DoD Components must plan, program, budget, and report on FRCS Cybersecurity IAW EI&E policy and guidance.
