Which international standard is focused on risk management processes and practices?

ISO 31000:2009 is the correct choice as it is a comprehensive international standard specifically dedicated to risk management. It provides guidelines and principles that organizations can adopt to improve their risk management processes and ensures that risk management is integrated into the organization's overall governance, strategy, and decision-making. The standard emphasizes a systematic and structured approach, focusing on understanding the context of risks, assessing, and treating them effectively.

By following ISO 31000, organizations can enhance their ability to manage risks in various domains effectively, ensuring they can achieve their objectives while minimizing the likelihood and impact of potential adverse events. The guidelines are designed to be adaptable across different industries and sectors, making it a versatile framework for managing risk on a global scale.

In contrast, other options, while related to security and management practices, do not primarily focus on risk management processes. NIST SP 800-53 is more concerned with security and privacy controls for federal information systems. ISO 9001 pertains to quality management systems and continual improvement. IEC 27001 is primarily focused on information security management systems, defining requirements for establishing, implementing, and maintaining information security. Each of these standards plays a critical role but does not center specifically on risk management processes as ISO 31000 does.
