01 Security

Is port 4450 dangerous?

We have no specific security note for port 4450. 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 4450, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4450'      # process listening on 4450
sudo lsof -nP -i :4450

macOS

sudo lsof -nP -i :4450

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4450 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4450
netstat -ano | findstr :4450

From another machine

nmap -p 4450 -sV <host>
sudo nmap -sU -p 4450 <host>
nc -zv <host> 4450

Block it in the firewall

sudo ufw deny 4450/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4450" -Direction Inbound -LocalPort 4450 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4450 used for?

Port 4450 is assigned by IANA to camp (Common ASCII Messaging Protocol).

Is port 4450 TCP or UDP?

Port 4450 is registered for TCP and UDP.

Is it safe to open port 4450?

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 4450 is open?

On Linux run "ss -ltnup 'sport = :4450'", on macOS "lsof -nP -i :4450", and on Windows "netstat -ano | findstr :4450" to see the local process. From another machine, "nmap -p 4450 <host>" shows whether it is reachable.
