01 Security

Is port 350 dangerous?

We have no specific security note for port 350. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 350, and is it reachable?

Linux

sudo ss -ltnup 'sport = :350'      # process listening on 350
sudo lsof -nP -i :350

macOS

sudo lsof -nP -i :350

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 350 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 350
netstat -ano | findstr :350

From another machine

nmap -p 350 -sV <host>
sudo nmap -sU -p 350 <host>
nc -zv <host> 350

Block it in the firewall

sudo ufw deny 350/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 350" -Direction Inbound -LocalPort 350 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 350 used for?

Port 350 is assigned by IANA to matip-type-a (MATIP Type A).

Is port 350 TCP or UDP?

Port 350 is registered for TCP and UDP.

Is it safe to open port 350?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 350 is open?

On Linux run "ss -ltnup 'sport = :350'", on macOS "lsof -nP -i :350", and on Windows "netstat -ano | findstr :350" to see the local process. From another machine, "nmap -p 350 <host>" shows whether it is reachable.
