01 Security

Is port 1488 dangerous?

We have no specific security note for port 1488. 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 1488, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1488'      # process listening on 1488
sudo lsof -nP -i :1488

macOS

sudo lsof -nP -i :1488

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1488 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1488
netstat -ano | findstr :1488

From another machine

nmap -p 1488 -sV <host>
sudo nmap -sU -p 1488 <host>
nc -zv <host> 1488

Block it in the firewall

sudo ufw deny 1488/tcp                                         # Linux (ufw)

What is port 1488 used for?

Port 1488 is assigned by IANA to docstor (DocStor).

Is port 1488 TCP or UDP?

Port 1488 is registered for TCP and UDP.

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 1488 is open?

On Linux run "ss -ltnup 'sport = :1488'", on macOS "lsof -nP -i :1488", and on Windows "netstat -ano | findstr :1488" to see the local process. From another machine, "nmap -p 1488 <host>" shows whether it is reachable.
