What is the Cyber Kill Chain?

Developed by Lockheed Martin, the Cyber Kill Chain is a framework that describes the 7 stages every cyber attack follows. By understanding each stage, defenders can build layered security controls that disrupt attacks before damage occurs.

Break the Chain Early
The earlier you detect and disrupt an attack in the kill chain, the less damage the attacker can do. Every stage you defend is a chance to stop the breach.
Defense in Depth
No single control stops every attack. The kill chain framework ensures you have overlapping defenses at every stage - so if one fails, the next catches it.
Know Your Adversary
By mapping threat actor behaviors to kill chain stages, you can predict where attacks will come from and invest in the defenses that matter most for your industry.
