Which of the following is not a risk management framework?

Key risk indicators (KRI) are not a risk management framework; rather, they are metrics used to measure the level of risk in an organization. KRIs help organizations evaluate and monitor risks by providing early warnings or indicators of potential risk events. They are important tools within a broader risk management strategy but do not constitute a standalone framework for managing risk.

The other choices represent established frameworks or guidelines that provide structured approaches for managing risk. For instance, the European Union Agency for Network and Information Security (ENISA) publishes risk management guidelines that organizations can adopt. NIST SP 800-37 outlines a risk management framework specifically for federal information systems and organizations, while ISO 31000:2009 provides principles and guidelines for effective risk management across various sectors. These frameworks offer comprehensive methodologies to identify, assess, and mitigate risks, which sets them apart from the concept of KRIs.
