Definition/Scope: The term tiger team originally started as a specialized group tasked with testing the effectiveness of an organization’s ability to protect assets by attempting to circumvent, defeat, or otherwise thwart that organization’s internal and external security. The term originated within the military to describe a team whose purpose is to penetrate security of "friendly" installations, and thus test their security measures. The members are professionals who install evidence of their success, e.g. leave cardboard signs saying "bomb" in critical defense installations, hand-lettered notes saying "Your codebooks have been stolen" (they usually have not been) inside safes, etc. Sometimes, after a successful penetration, a high-ranking security person will show up later for a "security review," and "find" the evidence. Alternately, the team can present evidence of their success in person; such scenarios usually involve consummated theft (i.e. of money) and can be legally shaky for the team’s members. A subset of tiger teams is professional hackers, testing the security of military computer installations by attempting remote attacks through networks or supposedly "secure" communication channels. In the computer security field, the term is now used less often, and more common terms are penetration testers or security testers. The term is still used to refer to any official inspection team or special "fire fighting" group called in to look at a problem from outside the box. Referring to a team set up solely in response to a specific situation or problem, without considering any wider or longer-term issues. The team typically operates (at least partially) outside the normal chain of command, and reports directly to a higher company officer. However it has been increasingly used as a term to denote a group that is being utilized to test or propose a new design, procedure, or tactic.
