01 Security

Is port 22800 dangerous?

We have no specific security note for port 22800. 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 22800, and is it reachable?

Linux

sudo ss -ltnup 'sport = :22800'      # process listening on 22800
sudo lsof -nP -i :22800

macOS

sudo lsof -nP -i :22800

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 22800 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 22800
netstat -ano | findstr :22800

From another machine

nmap -p 22800 -sV <host>
sudo nmap -sU -p 22800 <host>
nc -zv <host> 22800

Block it in the firewall

sudo ufw deny 22800/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 22800" -Direction Inbound -LocalPort 22800 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 22800 used for?

Port 22800 is assigned by IANA to aws-brf (Telerate Information Platform LAN).

Is port 22800 TCP or UDP?

Port 22800 is registered for TCP and UDP.

Is it safe to open port 22800?

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 22800 is open?

On Linux run "ss -ltnup 'sport = :22800'", on macOS "lsof -nP -i :22800", and on Windows "netstat -ano | findstr :22800" to see the local process. From another machine, "nmap -p 22800 <host>" shows whether it is reachable.
