v2.0 August 2014
https://www.dataprotection.ie/docimages/documents/GuidetoAuditProcessAug2014.pdf
“This guidance was originally published in 2009. This revised version has been updated to take account of legislative developments and to reflect any changes in the approach of the Office of the Data Protection Commissioner to the audit process. The guidance is designed to assist organisations selected for audit by the Office of the Data Protection Commissioner. It is hoped that
this resource will provide organisations holding personal data with a simple and clear basis to conduct a self-assessment of their compliance with their obligations under Irish Data Protection Law”
