# 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
