[coined by Usenetter Tom Maddox, popularized by William Gibson's cyberpunk SF novels: a contrived acronym for ‘Intrusion Countermeasure Electronics’] Security software (in Gibson's novels, software that responds to intrusion by attempting to immobilize or even literally kill the intruder).

Neither term is in serious use yet as of late 2002, but many hackers
find the metaphor attractive, and each may develop a denotation in the
future. In the meantime, the speculative usage could be confused with
‘ICE’, an acronym for in-circuit
emulator
.
In ironic reference to the speculative usage, however, some hackers and computer scientists formed ICE (International Cryptographic Experiment) in 1994. ICE is a consortium to promote uniform international access to strong cryptography.
