One of the driving forces in the ongoing development of cybersecurity initia-
tives in the United States is the National Institute of Standards and Technologyβs
(NIST) Cybersecurity Frameworks. These frameworks have been developed to
assist governmental and business organizations in the design and development
of systems and techniques to provide security for their critical infrastructure.
