ABSTRACT
Cybersecurity has multiple facets that range from net defense to investigation to proactive activities to mitigation postattack. The US response has been historically divided into law enforcement, defense, and intelligence agencies. These were all developed agencies prior to the increased focus on cybersecurity. Under the US governmental landscape, the chapter will discuss the executive branch oversight and the coordination approach as well as the most prevalent federal agencies involved in the cybersecurity response in the US. Numerous legislative actions and executive orders have been enacted to define "the lanes in the road" for lead roles and to facilitate the coordination, outreach, and liaison between the agencies. Traditionally, the National Security Council (NSC) is the main policy development and coordination arm of the administration. The Department of Homeland Security (DHS) has a number of agencies and offices responsible for multiple areas of cybersecurity.
