Is port 2988 dangerous?

We have no specific security note for port 2988. 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 2988, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2988'      # process listening on 2988
sudo lsof -nP -i :2988

macOS

sudo lsof -nP -i :2988

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2988 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2988
netstat -ano | findstr :2988

From another machine

nmap -p 2988 -sV <host>
sudo nmap -sU -p 2988 <host>
nc -zv <host> 2988

Block it in the firewall

sudo ufw deny 2988/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2988" -Direction Inbound -LocalPort 2988 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2988 used for?

Port 2988 is assigned by IANA to hippad (HIPPA Reporting Protocol).

Is port 2988 TCP or UDP?

Port 2988 is registered for TCP and UDP.

Is it safe to open port 2988?

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 2988 is open?

On Linux run "ss -ltnup 'sport = :2988'", on macOS "lsof -nP -i :2988", and on Windows "netstat -ano | findstr :2988" to see the local process. From another machine, "nmap -p 2988 <host>" shows whether it is reachable.
