Perimeter Security & API Abuse Mitigation

This document outlines the security benchmark and abuse mitigation mechanisms designed to protect the system perimeter against unauthorized API flooding, credential abuse, and unauthenticated request storms.

Security & Abuse Mitigation Test

Security Benchmark & Mitigation Overview

The system was subjected to simulated malicious request storms to evaluate edge-layer filtering, downstream isolation, and resource preservation.

1. Perimeter Defense

  • Detection & Interception: Successfully intercepted 100+ Malicious/Unauthenticated RPS (Requests Per Second) instantly at the gateway layer.

  • Layer Enforcement: Handled via Nginx and custom Flask middleware working in tandem at the network edge.

2. Instant Mitigation ("Fail-Fast" Mechanism)

  • Status Responses: Invalid or tokenless requests are rejected immediately before deeper processing occurs.

  • HTTP Standards: Returns precise standard status codes:

    • 401 Unauthorized (for missing or invalid tokens/credentials)

    • 429 Too Many Requests (for request flooding / rate-limiting violations)

3. Downstream Isolation

  • Traffic Segmentation: Unauthorized and abusive traffic is dropped completely at the edge.

  • Protected Components: Prevents garbage traffic from reaching sensitive internal layers, including:

    • Redis queues

    • Celery background workers

    • Primary database clusters

4. Resource Preservation

  • Overhead Impact: 0% computational overhead on core business logic.

  • System Availability: Ensures internal infrastructure remains 100% available and responsive for legitimate, authenticated users during an active attack or abuse attempt.
