01 Security

Is port 5228 dangerous?

We have no specific security note for port 5228. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:

  • Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
  • Never expose them to the Internet.
  • Rotate tokens and certificates and audit who has access.

03 Check it

Which program uses port 5228, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5228'      # process listening on 5228
sudo lsof -nP -i :5228

macOS

sudo lsof -nP -i :5228

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5228 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5228
netstat -ano | findstr :5228

From another machine

nmap -p 5228 -sV <host>
nc -zv <host> 5228

Block it in the firewall

sudo ufw deny 5228/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5228" -Direction Inbound -LocalPort 5228 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5228 used for?

Port 5228 is assigned by IANA to hpvroom (HP Virtual Room Service).

Is port 5228 TCP or UDP?

Port 5228 is registered for TCP.

Is it safe to open port 5228?

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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.

How do I check if port 5228 is open?

On Linux run "ss -ltnup 'sport = :5228'", on macOS "lsof -nP -i :5228", and on Windows "netstat -ano | findstr :5228" to see the local process. From another machine, "nmap -p 5228 <host>" shows whether it is reachable.
