    It depends what you are guarding against. If someone wants to get into
    _your_ system then it's worthless. OTOH, "you don't have to run faster
    than the bear, just faster than someone else": Moving your ssh access
    off port 22 means that someone doing a network scan of port 22 won't
    see your system. This is reasonable protection against script kiddies.

    Definitely, don't rely on it as your only security. But, IMHO, it is
    worth doing in addition to other security measures.
