API Security Testing
— Auth and Authorization Code Review
Proof-driven API Security Testing for organizations in Auth and Authorization Code Review. We deliver validated exploit evidence, not automated scanner noise.
Free Scoping CallAuth and Authorization Code Review delivery and security model
Application security review for sessions, roles, permissions, tenant boundaries, and object-level access decisions inside the codebase.
Focus areas
- Centralized role and permission checks
- Object-level authorization
- Tenant isolation and data leakage paths
- Session refresh, token, and revocation flows
Delivery notes
- Evidence is described with role and tenant scenarios
- The broken business rule and affected data are clarified
- Remediation is split by code ownership
Decision matrix
Auth and Authorization Code Review 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 |
|---|---|---|---|
| Centralized role and permission checks | Does Centralized role and permission checks create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | Evidence is described with role and tenant scenarios |
| Object-level authorization | Does Object-level authorization create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | The broken business rule and affected data are clarified |
| Tenant isolation and data leakage paths | Does Tenant isolation and data leakage paths create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | Remediation is split by code ownership |
| Session refresh, token, and revocation flows | Does Session refresh, token, and revocation flows create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in API Security Testing. | Evidence is described with role and tenant scenarios |
What if Centralized role and permission checks fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Object-level authorization fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Tenant isolation and data leakage paths fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.

Frequently Asked Questions
What decision does Auth and Authorization Code Review clarify?
Auth and Authorization Code Review clarifies exploitability, affected workflows, and release impact for API Security Testing with evidence rather than scanner noise.
What evidence is included in Auth and Authorization Code Review?
Evidence is described with role and tenant scenarios Also, The broken business rule and affected data are clarified. Retest criteria and ownership notes are included for closure.
How is this different from an automated scanner report?
Automated findings are not forwarded as-is; false positives are removed, abuse paths are proven, and remediation priority is explained.
