# Unified Kill Chain

## *<mark style="color:blue;">Overview</mark>*

The **Unified Kill Chain (UKC)** is a cybersecurity framework that combines elements of the **Lockheed Martin Cyber Kill Chain** and the **MITRE ATT\&CK Matrix** to provide a comprehensive model for understanding and mitigating cyber threats. It outlines the steps attackers take during a cyberattack, enabling defenders to detect, prevent, and respond more effectively.

### *<mark style="color:blue;">Purpose</mark>*

The UKC aims to:

* Provide a **structured view** of attack phases.
* Help organizations **identify vulnerabilities** in their defenses.
* Improve **incident response** and **threat hunting** by mapping attacker tactics.

### *<mark style="color:blue;">Structure of the Unified Kill Chain</mark>*

The UKC consists of **18 phases**, grouped into three broader categories:

| Phase  | Tactical Phase         | Technical Execution                                                                  | MITRE ATT\&CK Mapping | Common Tools/Tactics                    | Defensive Countermeasures                 |
