Entries not within acceptable bounds are detected. For example:
negative values for entries that should be positive,
values for future dates earlier than the present, and
pointers to locations outside of the user's addressable space might all be detected.
Complexity: In properly designed
systems, legitimate ranges for values should be known and violations should
be detectable. Many systems with limited detection capability turn off
bounds and similar checking for performance reasons, but few make the
implications explicit.
