Is port 3518 dangerous?

We have no specific security note for port 3518. 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 3518, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3518'      # process listening on 3518
sudo lsof -nP -i :3518

macOS

sudo lsof -nP -i :3518

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3518 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3518
netstat -ano | findstr :3518

From another machine

nmap -p 3518 -sV <host>
sudo nmap -sU -p 3518 <host>
nc -zv <host> 3518

Block it in the firewall

sudo ufw deny 3518/tcp                                         # Linux (ufw)

04 FAQ
What is port 3518 used for?

Port 3518 is assigned by IANA to artifact-msg (Artifact Message Server).

Is port 3518 TCP or UDP?

Port 3518 is registered for TCP and UDP.

Is it safe to open port 3518?

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 3518 is open?

On Linux run "ss -ltnup 'sport = :3518'", on macOS "lsof -nP -i :3518", and on Windows "netstat -ano | findstr :3518" to see the local process. From another machine, "nmap -p 3518 <host>" shows whether it is reachable.
