    Indeed a good step in cutting down on non-specific blanket scanning
    based attacks. Relatively little defence against a determined attacker
    going against you as a specific target however.

    One of the best reasons to advocate running remote access mechanisms, is
    the fact that it keeps your logs a lot cleaner. If all of a sudden you
    see some attempts to log-in you can be reasonably sure that it's a
    targeted attack rather than a blanket scan.

    This becomes useful when responding to the incident, blanket scans are
    an easy fix - however if someone appears to be targeting you
    specifically then there may be other ares of your infrastructure which
    require your attention and you will be able to respond appropriately.
