01 Security

Is port 453 dangerous?

We have no specific security note for port 453. 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 453, and is it reachable?

Linux

sudo ss -ltnup 'sport = :453'      # process listening on 453
sudo lsof -nP -i :453

macOS

sudo lsof -nP -i :453

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 453 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 453
netstat -ano | findstr :453

From another machine

nmap -p 453 -sV <host>
sudo nmap -sU -p 453 <host>
nc -zv <host> 453

Block it in the firewall

sudo ufw deny 453/tcp                                         # Linux (ufw)

What is port 453 used for?

Port 453 is assigned by IANA to creativeserver (CreativeServer).

Is port 453 TCP or UDP?

Port 453 is registered for TCP and UDP.

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 453 is open?

On Linux run "ss -ltnup 'sport = :453'", on macOS "lsof -nP -i :453", and on Windows "netstat -ano | findstr :453" to see the local process. From another machine, "nmap -p 453 <host>" shows whether it is reachable.
