Overview
API security is now the dominant breach vector. Broken Object Level Authorization (BOLA) alone causes ~40% of API breaches. Yet most "API security" work is HTTPS + API keys + vague "rate limiting" — which addresses none of the actual threats. The OWASP API Security Top 10 is specific, well-known, and largely ignored in practice because teams do not map controls to attacks.
The API Security Hardening Framework maps each OWASP API threat class to concrete controls with implementation patterns, covers authentication (OAuth 2.1, mTLS, PoP tokens), authorization (RBAC/ABAC/ReBAC at object and field level), input/output validation, rate limiting with bypass prevention, logging/observability, and secure-by-default defaults in API gateway configuration.
What you get: - OWASP API Top 10 → control mapping with code patterns - Authentication scheme selection (OAuth 2.1, mTLS, mutual-JWT, API keys) - Fine-grained authorization (RBAC, ABAC, ReBAC) at object and field level - Input validation (schema, sanitization, semantic) - Rate limiting (token bucket, sliding window, distributed) - Security logging and audit trail - API gateway hardening configuration - Threat model template and test protocol
Built for: backend engineers, API architects, platform/security teams, and CTOs who need API security that maps to actual attacks — not checkbox compliance lists.
