Definition: ANSI (American National Standards Institute): A standards body made up of industry representatives. For infosec purposes, the two interesting areas are the X9 standards for financial/ banking, and the X12 standards for EDI (also governing health-care transactions). Contrast: ANSI is the American representative to the ISO. ANSI is made up of industry, whereas NIST specifies standards only for use within government. From Hacking-Lexicon
