Threat Modeling

Threat modeling is a structured approach to identifying, quantifying, and addressing security risks in software systems by analyzing potential threats and vulnerabilities. It involves systematically evaluating system architecture, data flows, and trust boundaries to anticipate how attackers might exploit weaknesses. This proactive methodology helps prioritize security efforts and design defenses before implementation.

Also known as: Threat Driven Security, Threat Analysis, Security Threat Modeling, STRIDE, PASTA

Why learn Threat Modeling?

Developers should learn threat modeling to build secure-by-design applications, especially for systems handling sensitive data (e.g., financial, healthcare, or personal information) or critical infrastructure. It's essential during the design phase of software development to prevent costly security breaches and comply with regulations like GDPR or HIPAA, reducing remediation costs by addressing risks early.
