ValueMentor API Security Testing is a professional service that provides comprehensive security assessments for application programming interfaces. The service focuses on identifying and remediating vulnerabilities in API implementations to prevent data exposure, authentication failures, and unauthorized access. The service includes vulnerability assessment and penetration testing to identify weaknesses through scanning and simulated attacks. Authentication and authorization testing validates the strength of access controls. Input validation testing examines how APIs handle various inputs to prevent injection attacks. Business logic testing identifies flaws in application-specific workflows using manual and automated techniques. Security configuration reviews audit API settings, CORS rules, permissions, and default configurations against industry standards. Fuzz testing injects invalid or unexpected data to uncover hidden vulnerabilities and data exposure risks. The testing process begins with scope definition and information gathering, documenting API endpoints, functions, and data types. Vulnerability analysis combines automated tools and manual techniques. Data exposure checks ensure sensitive information is not unnecessarily revealed in API responses. Exploitation testing measures real-world impact of identified vulnerabilities. Detailed reports provide severity ratings, impact assessments, and remediation recommendations. The service includes support for remediation and retesting to validate fixes.
