The need for protection of personal data depends on how extensive or critical the processed data is. You should therefore analyse each processing operation:
If you process particularly extensive and/or particularly critical data, the protective measures must be correspondingly high. As you remember, critical data is primarily what is known as "Article 9 data". Article 9 GDPR describes "special categories of personal data":
(Rectical 38).
If it is not clear at first glance how high the risk of data processing is, the controller must carry out a more comprehensive investigation, e.g. in the form of a risk analysis. Together with their team, they critically scrutinise the processing of personal data, implement appropriate and suitable protective measures and, in case of doubt, carry out a risk assessment. You can find a template for this in the "Tools and Tools" course.
A data protection impact assessment (DPIA) must be carried out at the latest when the processing is likely to result in a high risk to the rights and freedoms of natural persons due to the nature, scope, circumstances and purposes of the processing. A data protection impact assessment evaluates the necessity and proportionality of a planned processing operation and defines clear security measures and procedures to protect personal data.
However, this measure is only necessary for really extensive and critical data processing. If you are interested in what a data protection impact assessment looks like, a group of interested parties has created a DPIA for the Corona App in 2020, which is publicly available: https://www.researchgate.net/publication/341097723_Data_Protection_Impact_Assessment_for_the_Corona_App.
