EDPB published Guideline on Data Breach Examples for Controllers

28. January 2021

On January 18th, 2021, the European Data Protection Board (EDPB) published their draft Guidelines 01/2021 on Examples regarding Data Breach Notification.

These Guidelines are supposed to give further support to Controllers alongside the initial Guidelines on Personal Data Breach Notification under the GDPR, adopted by the Article 29 Working Party in February 2018. These new Guidelines are meant to consider different types of situations that the Supervisory Authorities have come across in the last two and a half years since the implementation of the GDPR.

The EDPB’s intention is to assist Controllers in deciding how to handle data breaches, namely by identifying the factors that they must consider when conducting risk assessments to determine whether a breach must be reported to relevant Supervisory Authorities as well as if a notification to the affected Data Subjects is necessary.

The draft Guidelines present examples of common data breach scenarios, including:

• ransomware attacks, where a malicious code encrypts the personal data and the attacker subsequently asks the controller for a ransom in exchange for the decryption code
• data exfiltration attacks, which exploit vulnerabilities in online services offered by the controller and typically aim at copying, exfiltrating and abusing personal data for malicious purposes
• human errors resulting in data breaches that are fairly common and can be both intentional and unintentional
• lost or stolen devices and paper documents
• “mispostal” scenarios, that arise from human error without malicious intent
• social engineering, such as identity theft and email exfiltration

The draft Guidelines further emphasize key elements of data breach management and response that organizations should consider, namely:

• proactively identifying system vulnerabilities in order to prevent data breaches from happening in the first place
• assessing whether a breach is likely to result in a risk to the rights and freedoms of the Data Subject, the timing of this assessment and the importance of Controllers not delaying a notification because of unclear circumstances
• implementing plans, procedures and guidelines indicating how to handle data breaches that have clear reporting lines and persons responsible for the recovery process
• organizing regular trainings for employees to raise awareness on data breach management, and the latest developments in the area
• documenting breaches in each and every case, irrespective of the risk they pose

The Guidelines will be open for public consultation until March 2nd, 2021, during which the EDPB will gather feedback on the draft.
