Does anyone here use port knocking?


Hi

I randomly came across the idea of port knocking not too long ago, and thought it looked pretty useful.

I've read some of the critiques on the concept, but I think they were questioning it more as a security defence for servers. I'm aware that, say I owned a webserver or something, if people did know that I was running xyz services and found nothing on a portscan, they'd know instantly that port knocking was in operation and use whatever cracking tools - resulting in minimal extra security.

However, I don't have a big server, just my quiet workstation way out there that nobody is expecting to be offering any services. Therefore, it would be ideal in concealing whatever services I might be running from any opportunistic port scanners.

The strange thing is that when I looked for any software for linux out there, though there are a huge amount of projects, they almost all died somewhere between 2004 - 2005; I couldn't find a single active project.
(even " http://www.portknocking.org/ " 's most recent release was 2004...)

I avoid installing unmaintained software wherever possible as I have found for all sorts of reasons without variation that it is a bad idea. Especially for security software.

Do you use port knocking? If so, what program do you use?

Thanks

Hi.

As far as I'm aware, everyone who does this on Linux just uses an iptables script, e.g.

Check "Aldaba Knocking Suite", It allows two different mechanisms (SPA and Port Knocking), and the project is active.
Download it from aldabaknocking.com
