Hi,
Fwknop uses Single Packet Authorization. The idea is to ask the server to open port 22 once a secret password is provided. In this fashion, port 22 is effectively disabled until someone "knocks". This extra layer of security would make 0-day exploits much more difficult. It would be great if port-knocking could be added into existing SSL-based software. http://cipherdyne.org/fwknop/docs/SPA.html Thanks! |
