Checklist of ISO/IEC 27001-A.18.1.4 Privacy and protection of personally identifiable information


Information privacy is a critical aspect of any organization’s operations. 

The mishandling of personally identifiable information (PII) can lead to serious reputational and legal consequences for businesses. 

A.18.1.4 of the ISO 27001 standard provides guidelines for ensuring the privacy and protection of PII. In this article, we will discuss the importance of complying with A.18.1.4 and provide a sample checklist for implementing its requirements.

Sample Checklist:

  • Verify the existence of policies and procedures governing the collection, processing, and storage of PII.
  • Confirm that all staff handling PII are aware of the organization’s privacy policies and procedures.
  • Identify the privacy officer of the organization and confirm that they are aware of what attributes of PII are collected and processed/stored by the organization for employees, contractors, and other third-party staff.
  • Determine if the PII being collected is in line with legal and regulatory requirements.
  • Identify the information assets on which PII is stored, processed, and the channels for their communication.
  • Determine the access controls around PII and the level of access and roles of personnel who have access to these assets.
  • Confirm that appropriate technical and organizational measures have been implemented to protect PII from unauthorized access, disclosure, alteration, destruction, and other forms of misuse.


Ensuring the privacy and protection of PII is critical for any organization. 

Failing to comply with A.18.1.4 can lead to legal and reputational consequences. 

By following the sample checklist provided above, organizations can implement the necessary measures to protect PII and comply with ISO 27001 standards.
