- Bind the service to localhost or a private network, never to a public address.
- Enable authentication, use per-application accounts and require TLS.
- Watch for exposed Docker ports: publish them on 127.0.0.1 only.

Which program uses port 8102, and is it reachable?
Linux
sudo ss -ltnup 'sport = :8102' # process listening on 8102
sudo lsof -nP -i :8102macOS
sudo lsof -nP -i :8102
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 8102 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 8102 netstat -ano | findstr :8102
From another machine
nmap -p 8102 -sV <host> nc -zv <host> 8102
Block it in the firewall
sudo ufw deny 8102/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 8102" -Direction Inbound -LocalPort 8102 -Protocol TCP -Action Block # Windows
What is port 8102 used for?
Port 8102 is assigned by IANA to kz-migr (Oracle Kernel zones migration server).
Is port 8102 TCP or UDP?
Port 8102 is registered for TCP.
Is it safe to open port 8102?
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. Bind the service to localhost or a private network, never to a public address.
How do I check if port 8102 is open?
On Linux run "ss -ltnup 'sport = :8102'", on macOS "lsof -nP -i :8102", and on Windows "netstat -ano | findstr :8102" to see the local process. From another machine, "nmap -p 8102 <host>" shows whether it is reachable.
