What’s the difference between ISO 27001 and 27701?

Information security standards enhance your security measures, demonstrate your security posture, and help you unlock business opportunities. However, it’s crucial to choose the right standard for your business. In this article, we’ll explore the similarities and differences between ISO 27001 and ISO 27701.

What is ISO 27701?

While ISO 27001 lays the groundwork for overall information security, ISO 27701 specifically addresses the management of personal data (PII). This standard provides a framework for organizations to establish, implement, maintain, and continually improve a Privacy Information Management System (PIMS).  

Key Components of ISO 27701

ISO 27701 extends the structure of ISO 27001 with additional clauses focused on privacy:

• Clause 5: Data protection: Incorporates security controls from ISO 27001 to safeguard personal data.  
• Clause 6: PIMS guidance: Outlines how to integrate privacy considerations into overall information security management.  
• Clause 7: PII controller guidance: Defines responsibilities for organizations that determine the purposes and means of processing PII.
• Clause 8: PII processor guidance: Specifies obligations for organizations that process PII on behalf of controllers.

By adhering to ISO 27701, organizations can effectively manage privacy risks, demonstrate compliance with data protection regulations (such as GDPR, CCPA, and HIPAA), and build trust with stakeholders.  

What is ISO 27001?

ISO 27001 is the globally recognized standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). It provides a comprehensive framework for protecting an organization’s confidential, integral, and available information.  

By adhering to ISO 27001, organizations can:

• Safeguard sensitive data: Protect against threats, vulnerabilities, and data breaches.
• Demonstrate security commitment: Build trust with stakeholders through a robust security posture.
• Meet compliance requirements: Adhere to industry regulations and legal obligations.

Key Clauses of ISO 27001

ISO 27001 outlines a structured approach to information security management, encompassing:

• Clause 4: Context of the organization: Understanding the organization’s internal and external environment to identify information security risks and opportunities.
• Clause 5: Leadership: Demonstrating top-level commitment to information security and assigning responsibilities.
• Clause 6: Planning: Establishing the scope of the ISMS, defining objectives, and developing plans to achieve them.
• Clause 7: Support: Providing resources, roles, responsibilities, and competencies to ensure the ISMS functions effectively.
• Clause 8: Operation: Implementing controls to manage risks, protect information assets, and ensure the continuity of information services.
• Clause 9: Performance evaluation: Monitoring, measuring, and reporting on ISMS performance.
• Clause 10: Improvement: Continuously improving the ISMS through regular reviews and corrective actions.

To achieve ISO 27001 certification, organizations must implement the applicable controls listed in Annex A of the standard.

ISO 27001 vs. ISO 27701: Key Differences

While both part of the ISO 27000 family, ISO 27001 and ISO 27701 serve distinct purposes in protecting organizational information.

Feature	ISO 27001	ISO 27701
Focus	Information Security Management System (ISMS)	Privacy Information Management System (PIMS)
Goal	Protect organizational assets from various threats	Protect individual privacy rights
Data Protection	General	Focuses on Personally Identifiable Information (PII)
Compliance	Industry-specific and legal requirements	Data protection regulations (e.g., GDPR, CCPA)
Clauses	1-10	Extends ISO 27001 with additional clauses (5-8)
Certification	Requires an audit	Requires an audit
Standards Alignment	Serves as a Stand alone	Is an extension of ISO 27001; you must be ISO 27001 certified before pursuing ISO 27701 or pursue them concurrently
Key Considerations	Risk assessment, access control, incident management	Data mapping, privacy impact assessments, data subject rights
Scope	Broad, covering all types of information assets	Specific to personal data (PII)

ISO 27001 vs. ISO 27701: Similarities

While ISO 27001 and ISO 27701 have distinct focuses, they share several commonalities:

• Standardization: Both are internationally recognized standards developed by the International Organization for Standardization (ISO).  
• Third-party certification: Achieving certification for either standard requires an independent audit by a certified body.  
• Risk management: Both standards emphasize the importance of identifying, assessing, and treating risks.
• Continuous improvement: Both require organizations to continually evaluate and enhance their management systems.
• Documentation: Extensive documentation is essential for both standards to demonstrate compliance.

By understanding both standards and their interconnections, organizations can effectively manage information security and privacy risks.

Can you get ISO 27701 certified without an ISO 27001 certification?

While organizations can receive an ISO 27001 certification alone, you cannot receive an ISO 27701 certification without being ISO 27001 compliance. Data security is an important aspect of privacy which is why ISO 27001 compliance is included as Clause 5 of ISO 27701.

ISO 27701 certification is contingent upon having an existing ISO 27001 certification.

Conclusion

While ISO 27001 provides a comprehensive framework for information security, ISO 27701 specifically addresses the management of personal data. By implementing both standards, organizations can effectively protect sensitive information, mitigate risks, and demonstrate a strong commitment to data privacy.
