The more I hear here and read elsewhere, the more I moderate my position
- I do see usefulness in it, but I still don't plan to use it.
I agree that "security through obscurity" is a useful, if small, part of
"security in depth".
In my case I don't choose to use portknocking, but now that I've
researched more about it, including rebuttals to some of the criticisms,
I've come to appreciate it better. I might use it under the right
circumstances.
