The Cyber Kill Chain and MITRE ATT&CK describe cyberattacks at different levels. Lockheed Martin’s Kill Chain presents seven ordered phases as a concise storyline; MITRE ATT&CK provides a detailed vocabulary for describing adversary behavior, from tactical goals to specific procedures. They are complementary, not competing frameworks: use the Kill Chain to orient a narrative and ATT&CK to add behavioral detail and support detection analysis.
What is the difference between the Cyber Kill Chain and MITRE ATT&CK?
The central difference is structure. The Cyber Kill Chain arranges an intrusion into a high-level sequence of phases. ATT&CK organizes observed adversary behavior around tactics and techniques, without requiring every operation to follow one fixed order.
MITRE’s official FAQ explains that “ATT&CK Tactics are unordered and may not all occur in a single intrusion because adversary tactical goals change throughout an operation, whereas the Cyber Kill Chain uses ordered phases to describe high level adversary objectives.” That distinction matters: a Kill Chain can make an incident easier to narrate, while ATT&CK can describe what the adversary did with more precision.

What are the seven Cyber Kill Chain stages?
Lockheed Martin developed the Cyber Kill Chain as part of its Intelligence Driven Defense model. Its seven phases are presented in order, from activity before an attack reaches a target through the adversary’s objectives. [Lockheed Martin: Cyber Kill Chain] [Lockheed Martin Cyber Kill Chain overview PDF]
#1 Best Overall
- Reconnaissance: The adversary gathers information about a potential target.
- Weaponization: The adversary prepares an attack capability for the intended target.
- Delivery: The attack is transmitted or otherwise introduced to the target.
- Exploitation: A vulnerability or other opportunity is used to execute the attack.
- Installation: The adversary establishes a foothold, such as by installing a capability.
- Command & Control: The adversary establishes a channel for communicating with compromised systems.
- Actions on Objectives: The adversary pursues the operation’s intended objective.
The sequence is useful for explaining how an operation may progress and for asking where defenses could disrupt it. Lockheed Martin’s overview expresses the defensive premise as: “Stopping adversaries at any stage breaks the chain of attack!” This is a framework principle, not a quantified guarantee that blocking any particular phase will always stop an incident.
How does MITRE ATT&CK describe adversary behavior?
MITRE ATT&CK is a knowledge base of adversary techniques grounded in real-world observations. Its terminology separates the goal of an action from the method and the observed implementation. [MITRE ATT&CK: Get Started]
- Tactic: Why an adversary acts—the tactical goal being pursued.
- Technique: How the adversary achieves a tactical goal.
- Sub-technique: A more specific description of a technique’s behavior.
- Procedure: The particular way an adversary implements a technique in an operation.
ATT&CK covers Enterprise, Mobile, and ICS domains. MITRE also describes using ATT&CK to help defenders develop analytics for detecting adversary techniques. Because the knowledge base changes over time, cite a dated version when a specific set of content or mappings matters. For example, MITRE’s October 2025 update describes changes in v18, including Detection Strategies and Analytics; that dated update alone does not establish which version is current now. [MITRE ATT&CK updates]
How do the Kill Chain stages map to ATT&CK?
There is no reliable one-to-one translation in which each Kill Chain phase equals a single ATT&CK tactic or technique. The models organize information differently: one provides ordered phases, while the other describes tactical goals and behaviors that can appear in changing combinations. A linear phase can help tell an incident story without implying that real intrusions always proceed cleanly from one stage to the next.
Rank #3
For a practical analysis, use a Kill Chain phase as a broad point of orientation, then attach ATT&CK labels only where the evidence supports them. For example, a report might place an observed activity in the broad narrative of gaining access, then identify the applicable ATT&CK tactic and technique based on what investigators actually observed. Do not infer a specific procedure simply from the phase name.
When should you use each framework—or both?
Use the Cyber Kill Chain for an ordered incident narrative
Choose the Kill Chain when the reader needs a compact explanation of what happened before entry, how access was gained, what foothold or control followed, and what objective was pursued. Its phases can also help defenders discuss possible interruption points across the progression.
Use ATT&CK for behavioral specificity
Choose ATT&CK when an investigation or defense task needs to identify the adversary’s tactical goal, the technique or sub-technique used, and—when evidence allows—the specific procedure. This vocabulary is better suited to describing behaviors and considering analytics that may detect them.

In a combined view, the Kill Chain gives the audience a high-level storyline, while ATT&CK labels make supported observations and detection coverage more specific. Treat the result as a useful synthesis, not a canonical crosswalk: not every behavior fits neatly into exactly one phase, and an operation’s goals can shift or recur.

How can a stage-by-stage protection matrix help?
Lockheed Martin’s application guidance describes displaying protections by Kill Chain stage and countermeasure to make potential coverage gaps visible. Such a matrix can support planning and help identify areas for investigation or investment; it is not proof that a listed protection works effectively in practice. [Lockheed Martin application guide]
For a useful matrix, keep the phase-level view connected to evidence about actual controls and observed behavior. A blank or thinly covered phase can flag a question to investigate, but the framework alone cannot establish whether a control is deployed correctly, detects relevant activity, or performs as intended.
