ISO 27701 is a worldwide standard that provides guidance on establishing, implementing, maintaining, and improving a privacy information management system (PIMS) as an extension to ISO 27001 and ISO 27002 for privacy management within an organisation’s context.
Organisations can use ISO 27701 to protect the privacy of personally identifiable information (PII) and comply with various privacy laws and regulations, such as the General Data Protection Regulation (GDPR) and the Protection of Personal Information Act (POPIA).
By implementing ISO 27701, organisations can improve their cybersecurity posture, reduce data subjects’ privacy rights risks, and demonstrate next-level data protection and trust with customers, partners, regulators, and other stakeholders.
This article will explain how ISO 27701 can be integrated with ISO 27001 and ISO 27002 to create a comprehensive information security management system. We’ll begin by briefly describing ISO 27001 and ISO 27002 and how they provide a framework for information security management. Then, we’ll explore how ISO 27701 adds specific requirements and guidance for privacy information management to the existing framework. Finally, we’ll outline a step-by-step approach for integrating ISO 27701 with ISO 27001 and ISO 27002.
ISO 27001 and ISO 27002: The Foundation of Information Security Management 🛡️
ISO 27001 and ISO 27002 are international standards that provide a framework for information security management systems (ISMS) and their requirements. An ISMS is a systematic approach to managing the security of information assets, such as financial information, intellectual property, employee data, and information entrusted by third parties.
The key elements of an ISMS are:
- Risk assessment: identifying the information assets, threats, and vulnerabilities and assessing their confidentiality, integrity, and availability risks.
- Security controls: selecting and implementing appropriate measures to mitigate the risks based on the organization’s objectives, legal obligations, and best practices.
- Policies and procedures: documenting and communicating the organization’s roles, responsibilities, rules, and guidelines for information security.
- Monitoring and review: measuring and evaluating the performance and effectiveness of the ISMS using audits, reviews, and indicators.
- Continual improvement: identifying and implementing opportunities for enhancing the ISMS based on feedback and internal and external environment changes.
By implementing an ISMS, organizations can protect their information assets from various threats and vulnerabilities, such as cyber-attacks, natural disasters, human errors, sabotage, and theft.
Organizations can benefit from implementing an ISMS by:
- Improving their business resilience and continuity 🚀
- Reducing their operational costs and losses 💰
- Enhancing their customer satisfaction and loyalty 🤝
- Complying with their legal and contractual obligations 📝
- Gaining a competitive advantage in the market 🏆
ISO 27701: The Privacy Extension to ISO 27001 and ISO 27002 🔒
ISO 27701 is an international standard that provides requirements and guidance for establishing, implementing, maintaining, and continually improving a privacy information management system (PIMS) in the form of an extension to ISO 27001 and ISO 27002 for privacy management within the context of the organization.
The main objectives of ISO 27701 are:
- To enhance the protection of personally identifiable information (PII) and reduce the risks to the privacy rights of data subjects.
- To ensure compliance with applicable privacy laws and regulations, such as GDPR, POPIA, LGPD, and Australian Privacy Principles.
- To demonstrate accountability and transparency for PII processing activities and provide evidence of compliance with relevant requirements.
- To build trust and reputation among customers, partners, regulators, and other stakeholders.
ISO 27701 comprises four clauses (Introduction, Scope, Normative References, Terms and Definitions) and six annexes (A to F). The clauses provide general information about the standard and its applicability, while the annexes provide specific requirements and guidance for PII controllers and processors.
The annexes include mappings with other privacy regulations and standards, such as GDPR, POPIA, LGPD, Australia Privacy Principles, APEC Privacy Framework, OECD Privacy Guidelines, and ISO 29100.
How to Integrate ISO 27701 with ISO 27001 and ISO 27002 🤝
Organizations that have already implemented an ISMS based on ISO 27001 and ISO 27002 can integrate ISO 27701 by following a step-by-step approach:
- Determine the scope and boundaries of the PIMS: define the objectives, scope, context, and interested parties of the PIMS, as well as the PII processing activities, systems, and locations covered by the PIMS.
- Define the roles and responsibilities of PII controllers and processors: identify and document the roles and responsibilities of the organization and its partners in relation to PII processing, such as PII controller, PII processor, joint controller, or sub-processor. Establish agreements and contracts that specify the obligations and expectations of each party.
- Conduct a privacy risk assessment and identify applicable legal requirements: identify and assess the privacy risks to data subjects arising from PII processing activities using a methodology consistent with ISO 27005. Identify and document the legal requirements for the organization’s PII processing activities, such as GDPR, POPIA, LGPD, or Australian Privacy Principles.
- Select and implement appropriate privacy controls from Annexes A to D of ISO 27701: select and implement the privacy controls relevant to the organization’s role as a PII controller or a PII processor based on the results of the privacy risk assessment and the legal requirements. Annexes A to D of ISO 27701 provide specific requirements and guidance for each role and mappings with other privacy regulations and standards.
- Establish policies and procedures for privacy information management: develop and document policies and procedures that support the implementation of the privacy controls, such as data protection policy, data subject rights policy, data breach response policy, data retention policy, data transfer policy, etc. Communicate and train relevant personnel on these policies and procedures.
- Monitor, measure, audit, and review the performance of the PIMS: establish methods and indicators to monitor and measure the effectiveness of the privacy controls. Conduct internal audits to verify compliance with ISO 27701 requirements. Conduct management reviews to evaluate the suitability, adequacy, and effectiveness of the PIMS. Address any issues or opportunities for improvement identified by these activities.
- Address nonconformities and take corrective actions: identify and report any nonconformities or incidents related to privacy information management. Analyze their causes and impacts. Take corrective measures to prevent recurrence or mitigate consequences. Document these actions and their results.
- Continually improve the PIMS based on feedback and changes: monitor changes in the internal and external environment that may affect the PIMS, such as new technologies, business processes, regulations, or stakeholder expectations. Identify opportunities for improvement based on feedback from data subjects, customers, partners, regulators, or other sources. Implement improvement actions based on priorities and resources.
Let’s wrap it up 🎉
ISO 27701 provides organizations with a framework for managing the privacy of personally identifiable information (PII) within the context of their information security management system (ISMS). By integrating ISO 27701 with ISO 27001 and ISO 27002, organizations can enhance their data protection, comply with various privacy laws and regulations, and demonstrate accountability and transparency for their PII processing activities.
The step-by-step approach for integrating ISO 27701 with ISO 27001 and ISO 27002 involves defining the scope and boundaries of the PIMS, identifying roles and responsibilities, conducting a privacy risk assessment, selecting and implementing appropriate privacy controls, establishing policies and procedures, monitoring and measuring the performance of the PIMS, addressing nonconformities, and continually improving the PIMS based on feedback and changes.
By following this approach, organizations can benefit from next-level data protection, integration with leading information security standards, compliance with privacy regulations, transparency and accountability for PII processing activities, improved overall cybersecurity posture, and reduced risks to the privacy rights of data subjects.
