Request Body Size Limiting + +**Issue:** Large payloads could cause memory exhaustion or DoS. + +**Solution:** +- Express JSON limit: 1MB +- Metadata field size limit: 4KB +- Description field length limit: 500 characters + +**Code:** [/backend/src/index.js](../backend/src/index.js) + +### 9. Security Event Logging + +**Issues:** +- Insufficient security event tracking +- Unable to detect attacks + +**Solution:** +- Comprehensive security event logging +- Events tracked: + - Missing/invalid API keys + - Authentication failures + - Registration attempts + - Key rotations + - Payment verification + - CORS violations + - Validation failures +- Sensitive data filtering in logs + +**Code:** [/backend/src/lib/security.js](../backend/src/lib/security.js) + +### 10. API Key Generation Enhancement + +**Issue:** API key entropy and format consistency. + +**Solution:** +- High-entropy key generation: randomBytes(24) = 192 bits +- Standardized format: `sk_` prefix + hex string +- Webhook secrets: `whsec_` prefix for distinction + +**Code:** [/backend/src/routes/merchants.js](../backend/src/routes/merchants.js) + +### 11. Production Environment Safeguards + +**Issues:** +- API docs exposed in production +- Debug information leaked + +**Solution:** +- Swagger UI only available in non-production +- Environment-based error verbosity +- Environment variable: NODE_ENV validation + +**Code:** [/backend/src/index.js](../backend/src/index.js) + +### 12. Database Connection Security + +**Already Implemented - Verified:** +- Connection pooling with limits (max: 10 connections) +- Idle timeout: 30 seconds +- Connection timeout: 5 seconds +- SSL enforcement for database connections + +**Code:** [/backend/src/lib/db.js](../backend/src/lib/db.js) + +## Testing + +### Security Tests Added + +Created comprehensive security validation tests in
