In cybersecurity, 'center of gravity' refers to the core asset, system, or process whose compromise would cause the greatest impact on an organization’s security posture. Identifying this center helps defenders prioritize resources and strategies to protect the most critical elements. The concept is borrowed from physics, where the center of gravity is the point at which the mass of an object is concentrated and balanced. In cyber defense, it represents the focal point that, if attacked or disrupted, could destabilize an organization’s operations or security. By understanding their center of gravity, organizations can better anticipate potential threats and reinforce their most vital assets.
