Security Features Implemented

Authentication & Authorization

JWT Token-based Authentication: Secure token generation and validation ✅ Password Hashing: bcrypt algorithm for secure password storage ✅ Role-based Access Control: Three roles (admin, operator, viewer) with proper permissions ✅ Token Expiration: Configurable token lifetime (default: 30 minutes) ✅ Protected Endpoints: All sensitive endpoints require authentication

API Security

CORS Configuration: Configurable allowed origins ✅ Input Validation: Pydantic models validate all API inputs ✅ SQL Injection Protection: SQLAlchemy ORM prevents SQL injection ✅ Rate Limiting Support: Infrastructure for API rate limiting configured ✅ HTTPS/TLS Support: SSL/TLS configuration included in deployment

Data Protection

Multi-tenant Isolation: Each ISP's data is isolated by ISP ID ✅ Database Encryption: PostgreSQL supports encryption at rest ✅ Secrets Management: Environment variables for sensitive data ✅ API Key Security: Cryptographically secure random API keys

Network Security

Docker Network Isolation: Services communicate on isolated Docker network ✅ Firewall Rules: UFW configuration in deployment guide ✅ Port Restrictions: Only necessary ports exposed ✅ Redis Security: Redis accessible only within Docker network

Security Considerations

Known Security Alerts

  1. Socket Binding to All Interfaces (0.0.0.0)
    • Location: backend/services/traffic_collector.py:95
    • Severity: Low
    • Status: Accepted by design
    • Justification: The traffic collector needs to receive NetFlow/sFlow/IPFIX data from external routers. This is secured by:
      • Docker network isolation
      • Firewall rules (UFW)
      • UDP-only traffic
      • No privileged operations on received data
    • Mitigation:
      • Deploy behind firewall
      • Restrict source IPs in firewall rules
      • Use Docker network policies

Recommendations for Production

Critical (Must Do)

  1. Change Default Secrets

    • Change SECRET_KEY in .env
    • Change database passwords
    • Generate strong API keys
  2. Enable SSL/TLS

    • Configure SSL certificates (Let's Encrypt)
    • Enable HTTPS for all endpoints
    • Use secure WebSocket (WSS)
  3. Configure Firewall

    • Enable UFW or iptables
    • Restrict incoming ports
    • Allow only necessary traffic
  4. Update ALLOWED_ORIGINS

    • Set proper domain in CORS configuration
    • Remove localhost from production

Important (Should Do)

  1. Enable Rate Limiting

    • Implement rate limiting for API endpoints
    • Protect against brute force attacks
  2. Set Up Monitoring

    • Monitor failed login attempts
    • Alert on suspicious activity
    • Log security events
  3. Regular Updates

    • Keep dependencies updated
    • Apply security patches
    • Monitor CVE databases
  4. Backup Security

    • Encrypt backups
    • Secure backup storage
    • Test restore procedures

Optional (Nice to Have)

  1. Two-Factor Authentication

    • Add 2FA for admin accounts
    • Use TOTP or hardware keys
  2. IP Whitelisting

    • Whitelist admin IPs
    • Geo-blocking for management interface
  3. Security Headers

    • Add security headers (CSP, HSTS, etc.)
    • Implement Content Security Policy
  4. Audit Logging

    • Log all admin actions
    • Maintain audit trail
    • Regular security audits

Security Best Practices

For Developers

  • Never commit secrets to git
  • Use environment variables for sensitive data
  • Validate all user inputs
  • Use parameterized queries
  • Keep dependencies updated
  • Follow OWASP guidelines

For Operators

  • Use strong passwords
  • Enable 2FA where available
  • Regularly review access logs
  • Monitor for suspicious activity
  • Keep system updated
  • Regular security audits

For Administrators

  • Implement principle of least privilege
  • Regular security training
  • Incident response plan
  • Regular backups
  • Disaster recovery plan
  • Security policy documentation

Compliance Considerations

GDPR Compliance

  • User data minimization
  • Right to data deletion
  • Data breach notification procedures
  • Privacy policy required
  • User consent mechanisms

PCI DSS (if handling payments)

  • Secure payment processing
  • Never store credit card data
  • Use PCI-compliant payment gateways
  • Regular security assessments
  • Network segmentation

ISO 27001

  • Information security management
  • Risk assessment procedures
  • Security controls implementation
  • Regular audits and reviews
  • Continuous improvement

Incident Response

In Case of Security Breach

  1. Immediate Actions

    • Isolate affected systems
    • Preserve evidence
    • Notify stakeholders
    • Document everything
  2. Investigation

    • Determine scope of breach
    • Identify attack vector
    • Assess data exposure
    • Timeline reconstruction
  3. Remediation

    • Patch vulnerabilities
    • Update security measures
    • Rotate credentials
    • Restore from clean backups
  4. Post-Incident

    • Lessons learned review
    • Update security policies
    • User notification if required
    • Regulatory reporting
