- Patch VPN gateways quickly: they are a top initial access target.
- Use certificates or MFA rather than shared secrets.
- Investigate unexpected tunnels and proxies: they are also attacker tools.

Is it safe to open port 44322?
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. Patch VPN gateways quickly: they are a top initial access target.
How do I check if port 44322 is open?
On Linux run "ss -ltnup 'sport = :44322'", on macOS "lsof -nP -i :44322", and on Windows "netstat -ano | findstr :44322" to see the local process. From another machine, "nmap -p 44322 <host>" shows whether it is reachable.
