01 Security

Is port 1614 dangerous?

We have no specific security note for port 1614. 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 1614, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1614'      # process listening on 1614
sudo lsof -nP -i :1614

macOS

sudo lsof -nP -i :1614

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1614 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1614
netstat -ano | findstr :1614

From another machine

nmap -p 1614 -sV <host>
sudo nmap -sU -p 1614 <host>
nc -zv <host> 1614

Block it in the firewall

sudo ufw deny 1614/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1614" -Direction Inbound -LocalPort 1614 -Protocol TCP -Action Block  # Windows

What is port 1614 used for?

Port 1614 is assigned by IANA to netbill-cred (NetBill Credential Server).

Is port 1614 TCP or UDP?

Port 1614 is registered for TCP and UDP.

Is it safe to open port 1614?

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 1614 is open?

On Linux run "ss -ltnup 'sport = :1614'", on macOS "lsof -nP -i :1614", and on Windows "netstat -ano | findstr :1614" to see the local process. From another machine, "nmap -p 1614 <host>" shows whether it is reachable.
