Baseline controls are the minimum set of security requirements that apply to all information systems in an organization, regardless of their specific functions or characteristics. They are derived from the organization’s security policies, standards, and best practices, and they reflect the organization’s risk appetite and tolerance. Baseline controls provide a consistent and comprehensive foundation for the security of the information systems, and they can be tailored or supplemented by additional controls as needed for specific systems or situations. The other options are not as comprehensive as baseline controls, as they may only address certain aspects or aspects of the security requirements, or they may vary depending on the system or the context. For example, risk assessment results are an important input for defining the security requirements, but they are not the requirements themselves. Audit findings are an output of evaluating the compliance and effectiveness of the security requirements, but they are not the requirements themselves. Key risk indicators (KRIs) are metrics that measure the level of risk exposure and performance of the security requirements, but they are not the requirements themselves. References =
