Open Port notice

You see this notification pop up:

"Open Port"

Why did this happen?

An open port in your network was detected.

What are its risks?

A service called port is used to allow network communication for internet connected devices.

This port is like a door or hole and can be used as an entry point when sending and receiving data between the communication sources and the communication destination.

However, if there is a vulnerability in the Internet-connected devices, an unsecured setting or weak configuration can lead to unauthorized access that exploits this open port.

What should I do next?

1. Stop the unnecessary service (Open Port) or do appropriate access management.
2. Close the following ports if you are not using it:
   • FTP 21/TCP
   • SSH 22/TCP
   • TELNET 23/TCP
   • RPC 135/TCP
   • NETBIOS 137/TCP
   • NETBIOS 138/TCP
   • NETBIOS 139/TCP
   • MYSQL 3306/TCP
   • SMB 445/TCP
   • RDP 3389/TCP
   • VNC 5900/TCP

   You may check your router's manual or support website for the router and firewall configurations or contact the router vendor for assistance.

3. Update your devices to its latest firmware. Show me how.
4. Set a strong password on devices with open ports:
   • Create a password with at least 8 characters.
   • Use uppercase, and lowercase letters.
   • Use a mix of letters, numbers, and symbols.
5. Disconnect the device from your network if you are not using this device anymore.
