🔒N.L.D.S. Security Framework Design

Version: 1.0

Date: July 26, 2025

Status: Design Phase

Compliance: GDPR, SOC2, ISO27001, HIPAA Ready

---

📋 Security Architecture Overview

The N.L.D.S. Security Framework implements enterprise-grade security protocols with multi-layer protection, comprehensive audit trails, and compliance-ready features for the JAEGIS Enhanced Agent System v2.2.

🎯 Security Principles

• Zero Trust Architecture: Never trust, always verify

• Defense in Depth: Multiple security layers

• Principle of Least Privilege: Minimal access rights

• Data Protection by Design: Privacy and security built-in

• Continuous Monitoring: Real-time threat detection
