01 Security

Is port 1332 dangerous?

We have no specific security note for port 1332. 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 1332, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1332'      # process listening on 1332
sudo lsof -nP -i :1332

macOS

sudo lsof -nP -i :1332

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1332 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1332
netstat -ano | findstr :1332

From another machine

nmap -p 1332 -sV <host>
sudo nmap -sU -p 1332 <host>
nc -zv <host> 1332

Block it in the firewall

sudo ufw deny 1332/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1332" -Direction Inbound -LocalPort 1332 -Protocol TCP -Action Block  # Windows

What is port 1332 used for?

Port 1332 is assigned by IANA to pcia-rxp-b (PCIA RXP-B).

Is port 1332 TCP or UDP?

Port 1332 is registered for TCP and UDP.

Is it safe to open port 1332?

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 1332 is open?

On Linux run "ss -ltnup 'sport = :1332'", on macOS "lsof -nP -i :1332", and on Windows "netstat -ano | findstr :1332" to see the local process. From another machine, "nmap -p 1332 <host>" shows whether it is reachable.
