Who invented the Cyber Kill Chain Methodology?

• A. Lockheed Martin
• B. US Department of Homeland Security
• C. General Dynamics
• D. US Department of Defense

Answer: (A)

The idea being tested is who first introduced the Cyber Kill Chain framework. Lockheed Martin coined and popularized the Cyber Kill Chain as a way to break down a cyber intrusion into a sequence of attacker actions, from initial reconnaissance to achieving objectives. This framing helps defenders detect and disrupt attacks early by mapping security signals to specific stages in the intruder’s operation. Because Lockheed Martin developed and published the methodology, they are the originator of the concept, whereas the other organizations listed did not originate it.
