    Your questions indicate that you need to try harder at getting on the
    "Security Basics" mailing list. :-)

    Security is a tradeoff. -- Bruce Schneier

    Have you done all the basics first? They are basics because they are
    the kinds of things that give the most bang for the buck. You mention a
    firewall box, good. Has it been hardened? Do you have a good back up
    plan? Do you have a good restoration from back up plan? Are the
    systems fully patched? You need to ask and answer yourself these and
    other such system administration type questions.

    Then if you are still concerned you need to do a risk assessment. Who
    are you defending against? Script kiddies? Well financed criminals?
    The NSA? Is assuring availability of the systems worth the large
    additional effort of running an IDS for the marginal net gain? You may
    find that your energy is better spent on file integrity and back up.
    Every situation is different and you need to understand the basics so
    that you can evaluate these for yourself. Or hire a consultant that you
    trust to ask and answer these questions for you.
