Security & Compliance

Web Application Security

Security Headers

Protection Mechanisms

• Rate Limiting: 20 requests/minute, 200 requests/hour per user
• MIME Type Validation: Content verification before upload (malware prevention)
• Filename Sanitization: Prevents path traversal and injection attacks
• CORS Controls: Strict origin validation for cross-origin requests
• Idempotency Keys: Prevents duplicate uploads and ensures safe retries

Monitoring & Audit Trail

Application Monitoring

• Request Tracking: Unique request IDs for correlation and troubleshooting
• Error Logging: All errors logged without exposing sensitive data
• Prometheus Metrics: Real-time performance and health monitoring
• Health Checks: Automated container health monitoring with restart on failure

Audit Capabilities

• User Activity: File uploads tracked to specific user accounts
• Authentication Events: Login attempts and token validation logged
• Redis Tracking: Ownership and idempotency records with TTL
• S3 Access Logging: Every object access logged to dedicated log bucket

AWS Threat Detection & Audit Trail

AWS GuardDuty (Active)

• Non-Root User: Application runs as unprivileged user (UID 1000)
• Health Checks: Automatic container restart on failure
• Redis Password Auth: Password-protected Redis with resource limits

Operational Security

System Resilience

• Health Monitoring: Automated health checks with container restart
• Error Handling: Graceful error handling without information disclosure
