The Computer Oracle and Password System (COPS) was the first vulnerability scanner for Unix operating systems to achieve widespread use. It was created by Dan Farmer while he was a student at Purdue University. Gene Spafford helped Farmer start the project in 1989.


COPS is a software suite comprising at least 12 small vulnerability scanners, each programmed to audit one part of the operating system:[1]

After COPS, Farmer developed another vulnerability scanner called SATAN (Security Administrator Tool for Analyzing Networks).

COPS is generally considered obsolete, but it is not uncommon to find systems which are set up in an insecure manner that COPS will identify.
