Port Knocking in Action

Posted by CmdrTaco on from the crazy-security-through-obscurity dept.

tyldis writes "There was something called "port knocking" mentioned on Slashdot earlier, and now an implementation has sprung to life. Is this something worth pursuing?" The page is to an application called knockd which is a simple proof of concept with hard coded knock sequences. Really interesting stuff.

  1. Multiple kocks by TheJavaGuy · · Score: 0, Redundant

    I am not that familiar with port knocking, but what if multiple attempts from the same IP are made to access the port at the same time, Would the knocks then get all mixed up?

    Repeat after me...secrets are not security.

    Lazy programmers and closed source shops use methods like this to say the are secure when they are not.

    This can be detected and defeated by packet sniffing. So ISP's would be able to find them pretty easily.
