Step 2: Assessing the affected data

The DPC (Data Protection Commissioner) will ask an organisation reporting a data breach how many personal data records have been affected? How many data subjects could be affected? What categories of data could be affected?

To adequately report a breach, you first need to know what personal data you hold, as well as how and where it is stored. This will allow your organisation to accurately assess the scope and impact of the breach.

Mapping the data flows within your organisation will give you a complete understanding of all the personal data you process, as well as where and how you transfer it.
