Cyber defense
Strategically, cyber defence refers to operations that are conducted in the cyber domain in support of mission objectives. The main difference between cyber security and cyber defence is that cyber defence requires a shift from network assurance (security) to mission assurance. Cyber defence focuses on sensing, detecting, orienting, and engaging adversaries in order to assure mission success and to outmanoeuver the adversary. This shift from security to defence requires a strong emphasis on intelligence, and reconnaissance, and the integration of staff activities to include intelligence, operations, communications, and planning.
