What is the primary goal of the NIST Cybersecurity Framework?

Correct answer: Provide guidelines for managing cybersecurity risks in organizations

Option D is correct because the NIST Cybersecurity Framework (CSF) was developed to provide organizations with a voluntary, risk-based set of guidelines, best practices, and standards for identifying, protecting against, detecting, responding to, and recovering from cybersecurity threats, making risk management its central purpose. Option A is incorrect because the NIST CSF is not designed to replace existing security systems; it is a complementary framework that organizations apply on top of their existing controls. Option B is incorrect because while good security practices may reduce operational inefficiencies, reducing IT costs is not the primary goal of the NIST CSF. Option C is incorrect because no framework can guarantee the elimination of all cyber attacks; the CSF focuses on managing and reducing risk to acceptable levels rather than achieving perfect security.
