  • Serve it over HTTPS only and check the HTTP security headers.
  • Keep admin consoles and development servers off the Internet.
  • Patch the application server and remove default credentials and sample apps.

03 Check it

Which program uses port 8893, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8893'      # process listening on 8893
sudo lsof -nP -i :8893

macOS

sudo lsof -nP -i :8893

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8893 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8893
netstat -ano | findstr :8893

From another machine

nmap -p 8893 -sV <host>
sudo nmap -sU -p 8893 <host>
nc -zv <host> 8893

Block it in the firewall

04 FAQ
What is port 8893 used for?

Port 8893 is assigned by IANA to ddi-tcp-6 (Desktop Data TCP 5: NewsEDGE/Web application), ddi-udp-6 (Desktop Data UDP 5: NewsEDGE/Web application).

Is port 8893 TCP or UDP?

Port 8893 is registered for TCP and UDP.

Is it safe to open port 8893?

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. Serve it over HTTPS only and check the HTTP security headers.

How do I check if port 8893 is open?

On Linux run "ss -ltnup 'sport = :8893'", on macOS "lsof -nP -i :8893", and on Windows "netstat -ano | findstr :8893" to see the local process. From another machine, "nmap -p 8893 <host>" shows whether it is reachable.
