It is a cybersecurity framework developed by Lockheed Martin to help organizations understand, detect, and disrupt cyberattacks across different stages of an intrusion. The framework breaks an attack into a series of steps, allowing security teams to identify where defenses succeeded, where gaps exist, and how attackers progress toward their objectives.
Many cyberattacks do not occur through a single action. Instead, attackers move through multiple stages as they gather information, gain access, execute malicious code, and achieve their objectives.
The Lockheed Martin Cyber Kill Chain was developed to help security teams:
By analyzing attacks as a sequence of events, organizations can build more effective security controls.
The framework divides an attack into seven stages that describe how an intrusion typically progresses.
| Stage | Purpose |
|---|---|
| Reconnaissance | Gather information about the target |
| Weaponization | Prepare malicious payloads or tools |
| Delivery | Send the payload to the target |
| Exploitation | Trigger the vulnerability or attack |
| Installation | Establish a foothold on the system |
| Command and Control (C2) | Communicate with compromised systems |
| Actions on Objectives | Achieve attacker goals |
Although modern attack techniques continue to evolve, these stages remain useful for understanding many intrusion scenarios.
Security teams use the framework to map attack activity, improve visibility, and determine where an attack was detected or missed. The model can support both proactive and reactive security operations.
Organizations commonly apply the framework to:
This structured approach helps teams analyze attacks more consistently across different environments.
While the framework remains influential, it does not represent every modern attack perfectly. Cloud-native attacks, insider threats, identity-based attacks, and some advanced intrusion techniques may not follow the sequence exactly.
Common limitations include:
Consequently, many organizations use the framework alongside other models such as MITRE ATT&CK to gain broader visibility into adversary behavior.
Understanding where an attack fits within the Cyber Kill Chain often requires visibility into endpoint activity and incident context. Hexnode XDR helps security teams investigate suspicious behavior, review incidents, examine endpoint telemetry, and perform response actions from a centralized interface. During investigations, analysts can scan managed devices, access remote terminal capabilities, restart endpoints when necessary, and review activity associated with different stages of an intrusion. Alongside these workflows, Hexnode supports compliance enforcement, application management, VPN configuration, certificate management, and device policy administration across managed endpoints.
Yes. Although attack techniques have evolved, the framework remains a useful way to understand attacker progression and identify defensive opportunities.
The Cyber Kill Chain focuses on the stages of an attack, while MITRE ATT&CK provides a detailed catalog of adversary tactics and techniques.
Yes. One of the framework’s primary goals is to help defenders identify and disrupt attacks before attackers achieve their objectives.
