+# Security Considerations
+
+## Current Security Status
+
+### Known Issues
+The application currently shows some npm security warnings during build. These are primarily related to:
+
+1. **Development Dependencies**: Most vulnerabilities are in dev/build tools, not runtime dependencies
+2. **Transitive Dependencies**: Some warnings come from nested dependencies in React ecosystem
+3. **Deprecated Packages**: Some packages have newer alternatives but are still functional
+
+### Risk Assessment
+- **Runtime Risk**: LOW - vulnerabilities are mostly in build tools
+- **Production Impact**: MINIMAL - app runs in containerized environment
+- **Data Security**: SECURE - database isolated, HTTPS enforced
+
+### Mitigation Strategies
+
+#### Immediate (Already Implemented)
+- ✅ Database isolated on internal Docker network
+- ✅ HTTPS/TLS enforced via Traefik
+- ✅ JWT token-based authentication
+- ✅ Input validation and sanitization
+- ✅ Rate limiting on API endpoints
+- ✅ Security headers (CSP, HSTS, etc.)
+
+#### Ongoing Maintenance
+- 🔄 Regular dependency updates
+- 🔄 Security audit monitoring
+- 🔄 Container image updates
+
+## Production Deployment Security
+
+### Required Actions
+1. **Generate Secure JWT Secret**:
+   ```bash
+   openssl rand -base64 64
+   ```
+
+2. **Use Strong Database Password**:
+   ```bash
+   openssl rand -base64 32
+   ```
+
+3. **Environment Security**:
+   - Never commit `.env` files
+   - Use Docker secrets in production
+   - Rotate secrets regularly
+
+### Monitoring
+- Monitor application logs
+- Set up security alerts for failed authentication attempts
+- Regular security updates for base Docker images
+
+## Reporting Security Issues
+
+If you discover a security vulnerability, please:
+
+1. **Do not** open a public issue
+2. Email security concerns privately
+3. Provide detailed reproduction steps
+4. Allow time for investigation and patching
+
+## Security Updates
+
+This application follows semantic versioning with security patches:
+- **Patch releases** (x.x.X): Security fixes, safe to update immediately
+- **Minor releases** (x.X.x): New features, review before updating
+- **Major releases** (X.x.x): Breaking changes, test thoroughly
+
+## Best Practices
+
+### For Administrators
+- Keep base system updated
+- Monitor Docker security advisories
+- Use fail2ban for SSH protection
+- Regular backup testing
+
+### For Users
+- Use strong passwords
+- Enable 2FA when available
+- Report suspicious activity
+- Keep browsers updated
