Applying the first three steps in the RMF to legacy systems can be viewed as a ______ to determine if the necessary and sufficient security controls have been appropriately selected and allocated.

• A. Risk Assessment
• B. Due Diligence
• C. Gap Analysis
• D. Capital Planning

Answer: (C)

Conducting a gap analysis is crucial when applying the first three steps of the Risk Management Framework (RMF) to legacy systems. A gap analysis allows organizations to evaluate existing security controls against the required standards and best practices, identifying any deficiencies or areas that do not meet current security requirements. In this context, the first three steps of the RMF—categorizing the information system, selecting security controls, and implementing those controls—provide a foundational structure. By performing a gap analysis, an organization can ascertain whether the selected and implemented controls are both necessary and sufficient for the unique risks and characteristics of the legacy system. This process not only highlights areas where controls may be lacking but also facilitates informed decision-making about enhancements or updates needed to mitigate identified risks. The goal is to ensure that the legacy system aligns with current security practices and adequately protects against potential threats. The other options do not capture the specific nature of evaluating the suitability of existing security measures in comparison to required standards. Risk assessment primarily focuses on identifying and examining risks rather than evaluating control adequacy. Due diligence typically refers to the necessary investigation or audit processes before making business decisions and does not specifically apply to evaluating existing security controls. Capital planning deals with financial resources allocated for projects and does not
