Concept of
processing information with different classifications and categories that
simultaneously permits access by users with different security clearances and
denies access to users who lack authorization. [CNSSI_4009:2010]
(I) Describes an
information system that is trusted to contain, and maintain separation between,
resources (particularly stored data) of different security levels. (Examples: BLACKER,
CANEWARE, KSOS, Multics, SCOMP.)
Usage: Usually
understood to mean that the system permits concurrent access by users who
differ in their access authorizations, while denying users access to resources
for which they lack authorization.
[RFC4949:2007]
A class of system
containing information with different sensitivities that simultaneously permits
access by users with different security clearances and needs-to-know, but
prevents users from obtaining access to information for which they lack
authorization. [TCSEC:1985]
