- "[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 literally kill the intruder). Also,
`icebreaker': a program designed for cracking security on a system.
Neither term is in serious use yet as of mid-1993, 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". " - The
