What ISO 27k standard focuses on personal data and privacy guidance?

The correct choice focuses on personal data and privacy guidance specifically relevant to organizations managing personal information. The ISO/IEC 27701 standard provides a framework for establishing a Privacy Information Management System (PIMS), which is an extension of the existing ISO/IEC 27001 and 27002 standards. This standard aids organizations in ensuring compliance with data protection regulations, such as the GDPR, by providing guidelines for managing personal data securely and demonstrating accountability in the handling of that data.

ISO/IEC 27701 addresses the needs of various stakeholders, including data subjects and organizations that process personal data, making it a crucial standard for organizations seeking to enhance their privacy posture. It builds on the more general principles laid out in the 27000 series, specifically tailoring them to the privacy context.

The other options, while related to different aspects of information security and management, do not specifically focus on personal data and privacy.
