📚 Main Topics

1. Introduction to Network Security

   • Importance of following best practices in a home environment.
   • Security is unique to each setup and requires personal responsibility.

2. Internal Security Practices

   • VLANs (Virtual Local Area Networks)
     • Importance of segregating networks (e.g., devices, IoT, guest networks).
     • Use of isolation settings to enhance security.
   • Wi-Fi Network Security
     • Client device isolation to prevent communication between devices on the same access point.
   • Firewall Rules
     • Use of Ubiquiti zone-based firewall for easier management.
     • Creating zones for trusted and untrusted devices.
     • Limiting communication between VLANs to enhance security.

3. External Security Practices

   • Intrusion Detection and Prevention Systems (IDS/IPS)
     • Importance of enabling IDS/IPS for monitoring and blocking threats.
   • Port Forwarding
     • Recommendations to limit port forwarding and audit existing rules.
     • Strategies for limiting access based on IP addresses or geographic regions.
   • VPNs (Virtual Private Networks)
     • Recommended approach for accessing internal services securely.
     • Alternatives to port forwarding, such as Cloudflare Tunnels.

4. Monitoring and Maintenance

   • Importance of regular monitoring for security risks.
   • Utilizing insights and notifications for proactive security management.

✨ Key Takeaways

• Segregation is KeyUse VLANs to separate different types of devices and networks to minimize risk.
• Limit CommunicationApply the principle of least privilege by restricting communication between devices and networks.
• Use VPNsPrefer VPNs over port forwarding for secure remote access to internal services.
• Regular MonitoringContinuously monitor network activity and adjust security settings as needed.

🧠 Lessons Learned

• Security is an ongoing process that requires regular updates and adjustments.
• Best practices evolve, and staying informed is crucial for maintaining a secure network.
• Engaging with community feedback can provide additional insights and improvements to security practices.
