Attack Flow v3.0.0

Attack Flow is a language for describing how cyber adversaries combine and sequence various offensive techniques to achieve their goals. The project helps defenders and leaders understand how adversaries operate and improve their own defensive posture. This project is created and maintained by the MITRE Center for Threat-Informed Defense in futherance of our mission to advance the state of the art and the state of the practice in threat-informed defense globally. The project is funded by our research participants. The development of these usage guides has been shaped by direct input and feedback from our members—practitioners at large, international organizations with advanced cybersecurity programs. Their real-world experience and operational insights have grounded this work in practical, applicable guidance for defenders around the world.
