Which three assessment methods are defined by NIST Special Publications?

The correct answer identifies three assessment methods defined by NIST Special Publications, specifically in the context of evaluating security controls in information systems. "Examine," "Interview," and "Test" are key methods used to gather information about an organization's security posture.

• "Examine" involves a thorough review of the documented procedures, policies, and system configurations. This method helps in understanding how security measures are implemented and whether they are compliant with standards.

• "Interview" allows assessors to interact with personnel to gain insights on how security policies are applied in practice. This method helps validate the findings from the examination by incorporating firsthand accounts of the processes and practices in place.

• "Test" refers to the process of actively evaluating the effectiveness of security controls, often through simulated attacks or penetration tests. This is crucial for determining the actual resilience of the security measures against potential threats.

These three methods collectively provide a comprehensive approach to assess the effectiveness of security practices and policies, making it possible to identify vulnerabilities and areas for improvement in an organization's security framework. Other choices do not align with the specific assessment methods outlined by NIST, demonstrating a misunderstanding of the structured approach promoted in NIST guidelines.
