A panel of national security experts discusses what actions constitute a "cyber attack," when a state can respond to a cyber attack through the use of armed force and how the Law of Armed Conflict applies to cyber attacks and state responses. The panel consists of Col. Gary Corn, staff judge advocate to the United States Cyber Command; retired Col. Gary Brown, former staff judge advocate to the United States Cyber Command; retired Maj. Gen. Charles Dunlap Jr., executive director of the Center on Law, Ethics and National Security at Duke University; and Capt. Todd Huntley, faculty at the Army Judge Advocate General's Legal Center and School.
