# Security Framework: MT5 AI/ML XAUUSD Trading Bot

## Executive Summary

Comprehensive security framework addressing data protection, API security, deployment security, credential management, and compliance requirements for a production-grade algorithmic trading system.

## 1. Data Security

### 1.1 Encryption Standards
