To map trust boundaries, explicitly identify who controls untrusted inputs and authority, then enumerate abuse paths like authorization bypass, injection, and forged webhooks to apply targeted mitigations.

Securing webhook callbacks requires treating third-party callbacks as untrusted boundaries, mapping attacker paths for forged requests, and implementing signature verification evidence to prove defenses are effective.

Harden authentication and authorization by mapping trust boundaries around session tokens and secrets, enumerating abuse paths for bypass, and tying boundary-aligned mitigations to verification evidence like tests.

Protect sensitive PII and file upload data flows by mapping trust boundaries, enumerating abuse paths for injection or upload abuse, and applying boundary-aligned mitigations with verification evidence.

Yes, this approach applies to scenarios involving untrusted user input and third-party callbacks by requiring explicit boundary mapping, abuse enumeration, and verification evidence that demonstrates effective defenses.

Enumerating abuse paths first ensures your auth, secret validation, and callback defenses are directly aligned with mapped trust boundaries, providing verification evidence that the mitigations actually block attacks.
