Final answer:
The Committee on National Security Systems model is part of the United States' wider national security framework established by historical acts such as the National Security Act of 1947, and coordinates with military and civilian agencies to secure information systems.
Step-by-step explanation:
The Committee on National Security Systems (CNSS) model of information security is organized to serve as a central entity responsible for enhancing the security of the nation's information systems. It was an evolutionary product of the historical development of national security policies in the United States.
The National Security Act of 1947 was a pivotal point, creating critical institutions such as the National Security Council (NSC) and the Central Intelligence Agency (CIA), which have played essential roles in the country's intelligence and security operations.
The CNSS itself, which is concerned with the security of information systems that handle classified information, arises from the growing importance of cybersecurity in both governmental and military contexts.
As part of the government's overarching security apparatus, the CNSS model coordinates with military and civilian agencies to ensure information security standards are maintained across the various branches of the federal government.
This coordination is particularly crucial given the stature of foreign policy challenges and internal security threats faced by the nation.
Statutes such as the Homeland Security Act and Patriot Act further reflect the evolving measures taken by the government to safeguard against such threats, influencing the development and functions of entities like the CNSS.
