Decision matrix
Business Logic Testing is not just a service label; it states how each control is validated and which evidence is expected at closure.
| Control | Decision question | Validation | Expected evidence |
|---|---|---|---|
| Unauthorized transaction ordering | Does Unauthorized transaction ordering create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | Technical findings are explained through business impact |
| Limit and approval bypass scenarios | Does Limit and approval bypass scenarios create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | PoC steps are written for product teams to repeat |
| Price, coupon, and payment manipulation | Does Price, coupon, and payment manipulation create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | Fix guidance maps to control points and test cases |
| Cross-user and cross-tenant impact | Does Cross-user and cross-tenant impact create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | Technical findings are explained through business impact |
