threat_modeling

Threat modeling is a structured security practice to identify assets, map trust boundaries, and enumerate threats. Apply it during project kickoffs, architecture reviews, or when changing data flows, authentication, and external integrations.

Perform STRIDE threat analysis by evaluating spoofing, tampering, repudiation, information disclosure, denial of service, and privilege escalation across system components. This identifies actionable security guarantees and documents them in a formal threat model.

Map trust boundaries by clarifying data flows between clients, services, databases, and external integrations. Identify sensitive assets by discovering and categorizing credentials and business information requiring protection during architecture reviews.

Yes, threat modeling supports pre-deployment security assessments by producing documentation of security guarantees and remediation guidance. It evaluates risks across system components to guide secure design decisions and risk mitigation before release.

The best way to document security guarantees is generating a formal threat_model.md file. This consolidates asset discovery, trust boundary mapping, and STRIDE threats into actionable remediation guidance to support secure design.

You need threat modeling when changing authentication or external integrations because these modifications alter trust boundaries and data flows. The process surfaces new information disclosure and spoofing threats to update your security guarantees.
