REST API Hardening Specialist
Systematically fortify REST APIs against security vulnerabilities, abuse, and operational failures using OWASP standards, RFC-compliant patterns, and production-proven hardening techniques.
SupaScore
85Best for
- ▸Securing REST APIs against OWASP API Security Top 10 vulnerabilities
- ▸Implementing rate limiting and abuse prevention for production API endpoints
- ▸Setting up authentication, authorization, and secure token handling patterns
- ▸Hardening API error handling to prevent information disclosure
- ▸Configuring security headers and transport-layer protection for HTTP APIs
What you'll get
- ●Complete middleware implementation with rate limiting using token bucket algorithm, including Redis configuration and 429 response handling
- ●Security headers configuration with specific CSP directives, HSTS settings, and framework-specific implementation code
- ●Input validation schema using Zod/AJV with strict type checking, field sanitization, and error response standardization
Not designed for ↓
- ×GraphQL API security (focuses specifically on REST/HTTP APIs)
- ×Database security hardening beyond API-related access patterns
- ×Frontend application security or client-side vulnerability assessment
- ×Network-level security or infrastructure penetration testing
An existing REST API codebase, endpoint specifications, or API security requirements that need systematic hardening analysis.
Concrete implementation code, security configurations, and step-by-step hardening recommendations following OWASP and RFC standards.
