- 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.

From another machine

How do I check if port 2218 is open?
On Linux run "ss -ltnup 'sport = :2218'", on macOS "lsof -nP -i :2218", and on Windows "netstat -ano | findstr :2218" to see the local process. From another machine, "nmap -p 2218 <host>" shows whether it is reachable.
