Abstract: Cyber operations consist of many functions spanning cyber management,
cyber attack, cyber exploitation, and cyber defense, all including activities that are proactive, defensive, and regenerative in nature. A subset
of cyber defense, Active Cyber Defense (ACD) focuses on the integration and automation of many services and mechanisms to execute response actions
in cyber-relevant time. ACD is comprised of a set of logical functions to capture details from enterprise-level architecture to operational realization with
the primary objective to become a living part of DoD cyber operations to help defend the nation from cyber-based adversaries.
