By John M. Carroll. "Design and Audit for Systems Security." A corporate manual for creating systems to prevent fraud and embezzlement. (...I think. I glazed over when I saw equations in the text, ngl.)
A neat, straight 1982 first edition with minor edgewear to the jacket -- a small notch at the bottom of the back cover -- but very bright and clean inside, no notes or dog-ears. Utterly '80s cover design as well; not a bad reading or research pick-up.
