Is port 3590 dangerous?

We have no specific security note for port 3590. 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 3590, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3590'      # process listening on 3590
sudo lsof -nP -i :3590

macOS

sudo lsof -nP -i :3590

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3590 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3590
netstat -ano | findstr :3590

From another machine

nmap -p 3590 -sV <host>
sudo nmap -sU -p 3590 <host>
nc -zv <host> 3590

Block it in the firewall

sudo ufw deny 3590/tcp                                         # Linux (ufw)

What is port 3590 used for?

Port 3590 is assigned by IANA to wv-csp-sms (WV CSP SMS Binding).

Is port 3590 TCP or UDP?

Port 3590 is registered for TCP and UDP.

Is it safe to open port 3590?

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 3590 is open?

On Linux run "ss -ltnup 'sport = :3590'", on macOS "lsof -nP -i :3590", and on Windows "netstat -ano | findstr :3590" to see the local process. From another machine, "nmap -p 3590 <host>" shows whether it is reachable.
