Is port 3582 dangerous?

We have no specific security note for port 3582. 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 3582, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3582'      # process listening on 3582
sudo lsof -nP -i :3582

macOS

sudo lsof -nP -i :3582

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3582 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3582
netstat -ano | findstr :3582

From another machine

nmap -p 3582 -sV <host>
sudo nmap -sU -p 3582 <host>
nc -zv <host> 3582

Block it in the firewall

sudo ufw deny 3582/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3582" -Direction Inbound -LocalPort 3582 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3582 used for?

Port 3582 is assigned by IANA to press (PEG PRESS Server).

Is port 3582 TCP or UDP?

Port 3582 is registered for TCP and UDP.

Is it safe to open port 3582?

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 3582 is open?

On Linux run "ss -ltnup 'sport = :3582'", on macOS "lsof -nP -i :3582", and on Windows "netstat -ano | findstr :3582" to see the local process. From another machine, "nmap -p 3582 <host>" shows whether it is reachable.
