The application of which of the following standards would BEST reduce the potential for data breaches?

ISO 9000 is a quality management standard focused on product and service quality processes, not information security or data protection.

ISO 20121 is a sustainability management standard specifically for events and event supply chains, with no relevance to information security or data breach prevention.

ISO 26000 provides guidance on social responsibility and ethical behavior for organizations, but does not address information security controls or data breach prevention mechanisms.

ISO 27001 defines requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). It provides a risk-based framework with controls specifically designed to protect the confidentiality, integrity, and availability of information assets, directly addressing the root causes of data breaches through policies, access controls, encryption, and incident management.
