The Anatomy of Modern API Breaches: Beyond Basic Rate Limiting

The Evolution of API Attack Vectors

In modern microservice architectures, APIs have become the primary threat vector. Attackers rarely rely on brute-force attempts; instead, they exploit Broken Object Level Authorization (BOLA/IDOR) to access tenant data through legitimate API schemas.

Core Defense Recommendations 1. Enforce attribute-based access control (ABAC) at the gateway layer. 2. Adopt cryptographic tenant tokens. 3. Implement behavioral anomaly detection.
