JEFF DINGLE AND BOBBY E. RICKS
Generally, we can break security down into five levels: minimum, low,
medium, high, and maximum. As levels increase, everything from
the lower level is included in the higher level. For example, the poli-
cies, equipment, and procedures in the low and minimum levels are
included in the medium level.
