From the doc: ''tiger' is a set of scripts that scan a Un*x system looking for security problems, in the same fashion as Dan Farmer's COPS. 'tiger' was originally developed to provide a check of UNIX systems on the A&M campus that want to be accessed from off campus (clearance through the packetTiger filter). As such, we needed something that *anyone* could run if they could figure out how to get it down to their machine.'
