An information-system (IS) security mode of operation wherein each user with direct or indirect
access to the system, its peripherals, remote terminals, or remote hosts, has all of the following: (a)
a valid security clearance for all information within the system; (b) formal access approval and
signed nondisclosure agreements for all the information stored and/or processed (including all
compartments, sub compartments, and/or special access programs); and (c) a valid need-to-know
for all information contained within the IS. When in the dedicated security mode, a system is
specifically and exclusively dedicated to and controlled for the processing of one particular type or
classification of information, either for full-time operation or for a specified period of time.
