STRIDE threat modeling systematically categorizes security risks across six dimensions: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege. Apply STRIDE during architecture reviews to enumerate threats against each system component, then map mitigations to each threat class for comprehensive risk coverage.

STRIDE classifies threats by attack type across system components; attack trees decompose specific threats into hierarchical attack paths showing prerequisites and dependencies. Use STRIDE for broad threat enumeration and attack trees for deeper analysis of how attackers exploit individual threats, enabling more targeted security control planning.

Risk assessment scores threats by likelihood and impact using qualitative or quantitative methods, producing a prioritized list. Combine threat identification with risk scoring to focus security controls on high-impact vulnerabilities first, ensuring architecture decisions address the most critical risks within resource constraints.

Yes. Threat modeling applies directly to authentication flows by enumerating STRIDE threats specific to credential handling, session management, and identity verification. Document threats, mitigations, and required security controls to produce audit-ready authentication architecture that meets compliance requirements.

Threat modeling translates identified risks into concrete security requirements: specific controls mapped to each threat, risk scores, attack tree documentation, and audit-ready reports. These outputs drive architecture decisions, guide implementation, and provide evidence of proactive security design for compliance reviews.
