Z

zero day originally, the term [certain period] vulnerability

or exploit indicated relative ease of exploitation of

vulnerabilities or activity on the part of the blackhat

community: a “zero day” exploit was the theoretical

limit of vulnerability. However, recently the media

has used it in regard to software or video piracy,

generic antivirus detection, reward programs for

finding vulnerabilities, or even little known system

vulnerabilities or dangerous practices.Therefore, the

term has now been diluted to the point where it is

unlikely to be a useful reference, and may engender

confusion.

zerofill to fill unused storage locations with the value zero,

or representation of the character denoting it. Also

sometimes zeroize. See also DEADBEEF.
