01 Security

Is port 410 dangerous?

We have no specific security note for port 410. 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 410, and is it reachable?

Linux

sudo ss -ltnup 'sport = :410'      # process listening on 410
sudo lsof -nP -i :410

macOS

sudo lsof -nP -i :410

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 410 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 410
netstat -ano | findstr :410

From another machine

nmap -p 410 -sV <host>
sudo nmap -sU -p 410 <host>
nc -zv <host> 410

Block it in the firewall

sudo ufw deny 410/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 410" -Direction Inbound -LocalPort 410 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 410 used for?

Port 410 is assigned by IANA to decladebug (DECLadebug Remote Debug Protocol).

Is port 410 TCP or UDP?

Port 410 is registered for TCP and UDP.

Is it safe to open port 410?

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 410 is open?

On Linux run "ss -ltnup 'sport = :410'", on macOS "lsof -nP -i :410", and on Windows "netstat -ano | findstr :410" to see the local process. From another machine, "nmap -p 410 <host>" shows whether it is reachable.
