+### Security Controls
+
+#### 1. Network Security
+
+**Firewall Rules:**
+- Ingress: Only allow required ports (443, 8545, 5000)
+- Egress: Restrict outbound connections
+- Inter-container: No lateral movement by default
+
+**Network Segmentation:**
+- Separate VLANs for each tier
+- Isolated management network
+- DMZ for external-facing services
+
+#### 2. Authentication & Authorization
+
+**Multi-Factor Authentication:**
+- Required for all admin access
+- TOTP or hardware tokens
+- Biometric authentication (where supported)
+
+**Role-Based Access Control:**
+- Granular permissions
+- Principle of least privilege
+- Regular access reviews
+
+**API Authentication:**
+- mTLS for all API calls

+- API key rotation (90 days)
+
+#### 3. Data Protection
+
+**Encryption:**
+- At rest: AES-256 encryption
+- In transit: TLS 1.3
+- Key management: HSM-backed
+
+**Data Classification:**
+- PII: Highest protection
+- Financial data: High protection
