OWASP API Security Top 10
Coverage based on risk of common API authorization, data, resource, and inventory weaknesses.
Penetration testing
API Penetration Testing
A structured assessment of API endpoints, identities, permissions for individual objects, data flows, and abuse controls using representative roles and authorized test data.
Assessment scope
What is tested
The final test coverage is agreed during scoping and limited to systems for which written authorization has been provided.
Authorization for objects and functions
Authentication and token lifecycle
Input validation and injection
Rate limits and resource consumption
Sensitive data exposure
Inventory, versioning, and unsafe integrations
Engagement flow
Controlled from authorization to retest.
01
Scope & authorization
Define objectives, approved systems, constraints, test windows, contacts, and rules of engagement.
02
Discovery
Establish the authorized attack surface, architecture, user roles, assets, and applicable assessment criteria.
03
Controlled testing
Assess the approved scope using manual and technical methods appropriate to the environment.
04
Validation
Confirm findings safely, remove false positives, and establish practical technical and business impact.
05
Reporting
Receive findings supported by evidence, risk ratings, an executive summary, and remediation priorities.
06
Remediation review
Review proposed corrective actions and clarify implementation priorities with the assessment team.
07
Retest
Verify agreed fixes and record whether each tested finding has been resolved, reduced, or remains open.
