Threat Modeling

Threat modeling is a structured approach to identifying and prioritizing potential threats to your systems by analyzing your architecture, identifying assets worth protecting, enumerating potential attack vectors, and determining which threats pose the greatest risk. Common methodologies include STRIDE, PASTA, and attack trees.

Threat modeling should be performed during system design and updated when the system or threat landscape changes. It provides the analytical foundation for security architecture decisions — helping you focus your defenses on the threats most relevant to your specific environment and data.
