01 Security

Is port 614 dangerous?

We have no specific security note for port 614. 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 614, and is it reachable?

Linux

sudo ss -ltnup 'sport = :614'      # process listening on 614
sudo lsof -nP -i :614

macOS

sudo lsof -nP -i :614

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 614 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 614
netstat -ano | findstr :614

From another machine

nmap -p 614 -sV <host>
sudo nmap -sU -p 614 <host>
nc -zv <host> 614

Block it in the firewall

sudo ufw deny 614/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 614" -Direction Inbound -LocalPort 614 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 614 used for?

Port 614 is assigned by IANA to sshell (SSLshell).

Is port 614 TCP or UDP?

Port 614 is registered for TCP and UDP.

Is it safe to open port 614?

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 614 is open?

On Linux run "ss -ltnup 'sport = :614'", on macOS "lsof -nP -i :614", and on Windows "netstat -ano | findstr :614" to see the local process. From another machine, "nmap -p 614 <host>" shows whether it is reachable.
