Book excerpt: This manual describes the Department of Defense (DoD) Cyber Incident Handling Program and specifies its major processes, implementation requirements, and related U.S. government interactions. This program ensures an integrated capability to continually improve the Department of Defense's ability to rapidly identify and respond to cyber incidents that adversely affect DoD information networks and information systems (ISs). It does so in a way that is consistent, repeatable, quality driven, measurable, and understood across DoD organizations.
