The Cyber Kill Chain is a seven-phase model developed by Lockheed Martin that describes the stages of a cyberattack: reconnaissance, weaponization, delivery, exploitation, installation, command and control, and actions on objectives. Defenders use it to identify where they can detect or disrupt an attack at each phase.
Why Cyber Kill Chain Matters for Your Cybersecurity Career
The Kill Chain gives defenders a structured way to think about attack progression. SOC analysts use it to classify alerts by attack phase. Incident responders trace intrusions through Kill Chain stages. While ATT&CK has become more granular, the Kill Chain remains a useful mental model and appears on CompTIA and CISSP exam objectives.
