tiger team
     
        (US military jargon) 1. Originally, a team whose purpose is to
        penetrate security, and thus test security measures.  These
        people are paid professionals who do hacker-type tricks,
        e.g. leave cardboard signs saying "bomb" in critical defence
        installations, hand-lettered notes saying "Your codebooks have
        been stolen" (they usually haven't been) inside safes, etc.
        After a successful penetration, some high-ranking security
        type shows up the next morning for a "security review" and
        finds the sign, note, etc. and all hell breaks loose.  Serious
        successes of tiger teams sometimes lead to early retirement
        for base commanders and security officers (see the {patch}
        entry for an example).
     
        2. Recently, and more generally, any official inspection team
        or special {firefighting} group called in to look at a
        problem.
     
        A subset of tiger teams are professional {cracker}s, testing
        the security of military computer installations by attempting
        remote attacks via networks or supposedly "secure"
        communication channels.  Some of their escapades, if
        declassified, would probably rank among the greatest hacks of
        all times.  The term has been adopted in commercial
        computer-security circles in this more specific sense.
