Where you put lusers so they can't hurt anything. A program

that limits a luser to a carefully restricted subset of the

capabilities of the host system (for example, the "rsh"

utility on USG Unix). Note that this is different from an

iron box because it is overt and not aimed at enforcing

security so much as protecting others (and the luser) from

the consequences of the luser's boundless naivet'e (see

naive). Also "padded cell environment".
