What is ISO/IEC 29151?
ISO/IEC 29151 provides a code of practice for protecting personally identifiable information (PII) by establishing, implementing, and managing privacy controls based on ISO/IEC 27002 security controls framework.
Published in 2017, ISO/IEC 29151 was developed to help organizations protect personal data in an era of increasing privacy regulations like GDPR, CCPA, LGPD, and others. The standard builds on ISO/IEC 27002 information security controls by adding specific guidance for protecting PII throughout its lifecycle—from collection and processing to storage, transmission, and deletion.
The standard addresses 54 privacy-specific controls covering consent management, data minimization, purpose limitation, transparency, data subject rights, cross-border data transfers, breach notification, privacy by design, and third-party processor management. ISO/IEC 29151 helps organizations implement technical and organizational measures to protect personal data, demonstrate accountability, and comply with privacy regulations worldwide.
ISO/IEC 29151 is designed to complement ISO/IEC 27001 (Information Security) and ISO/IEC 27701 (Privacy Information Management), allowing organizations to integrate privacy protection with information security management.
