Kimova AI ISO 27001 Auditing Series Organization Control A.5.34 Privacy and Protection of Personally Identifiable Information (PII)

In today’s article at Kimova AI ISO 27001 auditing series, we focus on Organisational Control A.5.34, which addresses the Privacy and Protection of Personally Identifiable Information (PII). With the increasing collection and use of personal data, ensuring the privacy and protection of PII is a fundamental requirement for maintaining trust and complying with legal obligations like GDPR and other data protection laws.

Control A.5.34: Privacy and Protection of PII

Control A.5.34 is designed to ensure that organizations handle PII responsibly, protecting it from unauthorized access, misuse, or breach. It mandates the implementation of policies and technical measures to safeguard PII throughout its lifecycle, from collection to destruction.

Key Aspects of Control A.5.34

1. Data Minimization
   • Explanation: Organizations should only collect and process the minimum amount of PII necessary for the intended purpose.
   • Example: An e-commerce website should only collect customers’ shipping addresses if they are necessary for order fulfillment, avoiding the storage of unnecessary details like social security numbers.
2. Informed Consent
   • Explanation: Individuals must be informed about how their data will be used and provide explicit consent before their PII is collected or processed.
   • Example: A healthcare provider must obtain clear consent from patients before collecting their medical records for research purposes.
3. Data Security Measures
   • Explanation: Organizations must implement technical controls, such as encryption and access control, to protect PII from unauthorized access, alteration, or disclosure.
   • Example: A financial institution might encrypt all customer PII stored in its databases and restrict access to only authorized personnel with multi-factor authentication.
4. Right to Access, Modify, or Delete PII
   • Explanation: Individuals should have the right to access their personal data, request modifications, or request the deletion of their PII in compliance with applicable laws.
   • Example: Under GDPR, an individual can request a retail company to delete their stored account data after closing their account.
5. Breach Notification and Incident Response
   • Explanation: In the event of a data breach affecting PII, organizations must have processes in place to notify affected individuals and relevant authorities promptly.
   • Example: A social media company must inform users and regulators within 72 hours of discovering a data breach exposing PII, as required under GDPR.
6. Cross-Border Data Transfers
   • Explanation: When transferring PII across international borders, organizations must ensure compliance with data protection regulations of both the sending and receiving countries.
   • Example: A cloud service provider based in the US must ensure that personal data transferred from the EU complies with GDPR regulations, such as through the use of Standard Contractual Clauses (SCCs).

Conclusion

Protecting Personally Identifiable Information (PII) is essential for maintaining privacy and adhering to regulations like GDPR. Organizations must implement strong controls, such as data minimization, encryption, and breach response, to safeguard individuals’ personal data.
