About OWASP Threat Dragon

What is Threat Dragon?

OWASP Threat Dragon is a modeling tool used to create threat model diagrams as part of a secure development lifecycle. Threat Dragon follows the values and principles of the threat modeling manifesto. It can be used to record possible threats and decide on their mitigations, as well as giving a visual indication of the threat model components and threat surfaces. Threat Dragon runs either as a web application or as a desktop application. Threat Dragon supports STRIDE / LINDDUN / CIA / DIE / PLOT4ai, provides modeling diagrams and implements a rule engine to auto-generate threats and their mitigations.
