- 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 5575, and is it reachable?
Linux
sudo ss -ltnup 'sport = :5575' # process listening on 5575
sudo lsof -nP -i :5575macOS
sudo lsof -nP -i :5575
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 5575 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 5575 netstat -ano | findstr :5575
From another machine
nmap -p 5575 -sV <host> nc -zv <host> 5575
Block it in the firewall
sudo ufw deny 5575/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 5575" -Direction Inbound -LocalPort 5575 -Protocol TCP -Action Block # Windows
What is port 5575 used for?
Port 5575 is assigned by IANA to ora-oap (Oracle Access Protocol).
Is port 5575 TCP or UDP?
Port 5575 is registered for TCP.
Is it safe to open port 5575?
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 5575 is open?
On Linux run "ss -ltnup 'sport = :5575'", on macOS "lsof -nP -i :5575", and on Windows "netstat -ano | findstr :5575" to see the local process. From another machine, "nmap -p 5575 <host>" shows whether it is reachable.
