Is port 8074 dangerous?

We have no specific security note for port 8074. 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 8074, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8074'      # process listening on 8074
sudo lsof -nP -i :8074

macOS

sudo lsof -nP -i :8074

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8074 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8074
netstat -ano | findstr :8074

From another machine

nmap -p 8074 -sV <host>
sudo nmap -sU -p 8074 <host>
nc -zv <host> 8074

Block it in the firewall
