Threat modeling is a structured process for identifying security threats, vulnerabilities, and countermeasures in a system's design before code is written. Common approaches include STRIDE (classifying threat types), PASTA (risk-centric), and attack trees. Teams diagram data flows, identify trust boundaries, and enumerate how attackers could abuse each component.
Why Threat Modeling Matters for Your Cybersecurity Career
Threat modeling prevents security flaws at the design stage, where they are cheapest to fix. Security architects lead threat modeling sessions with engineering teams. This skill signals senior-level security thinking to employers. Organizations that threat model consistently find fewer vulnerabilities in penetration tests. CISSP and CASP+ exams cover threat modeling methodology.
