01 Security

Is port 1898 dangerous?

We have no specific security note for port 1898. 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 1898, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1898'      # process listening on 1898
sudo lsof -nP -i :1898

macOS

sudo lsof -nP -i :1898

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1898 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1898
netstat -ano | findstr :1898

From another machine

nmap -p 1898 -sV <host>
sudo nmap -sU -p 1898 <host>
nc -zv <host> 1898

Block it in the firewall

sudo ufw deny 1898/tcp                                         # Linux (ufw)

04 FAQ
What is port 1898 used for?

Port 1898 is assigned by IANA to cymtec-port (Cymtec secure management).

Is port 1898 TCP or UDP?

Port 1898 is registered for TCP and UDP.

Is it safe to open port 1898?

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 1898 is open?

On Linux run "ss -ltnup 'sport = :1898'", on macOS "lsof -nP -i :1898", and on Windows "netstat -ano | findstr :1898" to see the local process. From another machine, "nmap -p 1898 <host>" shows whether it is reachable.
