10 Essential Security Tips for Your Synology NAS

🧠 Introduction

Your NAS is a powerhouse of data — but it’s also a target if not secured properly.
Here are 10 practical steps to keep your Synology NAS safe and hacker-proof.

🔒 1. Change Default Ports

• Change DSM port from 5000/5001 to something unique.
  Control Panel → Network → DSM Settings

🧑‍💻 2. Disable Default Admin Account

Create a new admin user and disable the default one.

🔐 3. Enable Two-Factor Authentication

Adds a layer of protection even if your password leaks.

🌐 4. Use HTTPS

Install a free SSL certificate (Let’s Encrypt) under Control Panel → Security.

🧱 5. Enable Firewall Rules

Block access from unknown IPs and restrict DSM access.

📧 6. Set Up Auto Notifications

Get alerts for failed logins, SMART warnings, and updates.

🕵️ 7. Avoid Port Forwarding (Use QuickConnect/Tailscale)

Direct port exposure invites attacks. Use VPN or QuickConnect for remote access.

💾 8. Keep DSM Updated

Always update DSM and packages for security patches.

🔄 9. Backup Regularly

Use Hyper Backup to external drives or cloud destinations.

👥 10. Limit User Permissions

Only give access needed for each user — avoid granting full admin rights.
