3) Contents of a Personal Data Breach Notification

3.1: Information needed for notification to supervisory authority

When a personal data breach occurs, controllers and processors have the obligation to provide specific information in their notification to the supervisory authority. This information is essential for assessing the severity and potential risks of the breach and for enabling the authority to take appropriate measures.

The following details should be included in the notification:

a) Nature of the breach: Controllers and processors should describe the type of breach that occurred. For example, was it a result of a cyber-attack, accidental loss, or unauthorized access?

Specifying the nature of the breach helps authorities understand the mechanisms behind the incident. b) Categories and approximate number of individuals affected: Controllers and processors must identify the categories of individuals whose data was compromised.

This includes providing information on the approximate number of affected individuals. This helps the supervisory authority assess the scale and potential impact of the breach.

c) Consequences of the breach: Controllers and processors should provide an assessment of the potential consequences of the breach. This could involve explaining the risks to the rights and freedoms of the affected individuals, such as identity theft, financial loss, or reputational damage.

d) Measures taken or proposed to be taken: It is crucial to outline the steps that have been taken or are planned to address the breach and mitigate its potential adverse effects. This includes any IT or security measures put in place, as well as any communication strategies to inform affected individuals about the breach.

3.2: Phased disclosure of information

In some instances, it may not be possible to provide all relevant information at the initial stage of a data breach. However, this does not exempt controllers and processors from notifying the supervisory authority.

Instead, a phased approach to disclosure can be adopted, where additional information is provided as it becomes available. The aim is to ensure prompt notification while allowing for the necessary investigation and assessment of the incident.

Phased disclosure allows for the immediate reporting of the essential information, such as the fact that a breach has occurred and basic details about the breach. Subsequent updates can then be provided as more information is gathered.

This approach ensures that the supervisory authority receives timely notification and can take any necessary actions without delays caused by a complete assessment. The phased disclosure of information is beneficial for both the controllers or processors and the supervisory authorities.

Controllers and processors can fulfill their notification obligations promptly while still active investigations. These investigations may uncover further details regarding the nature and extent of the breach.

Supervisory authorities gain access to the initial information and can monitor the progress of the investigation, ensuring compliance with GDPR requirements.

4) Timeline and Risk Assessment for Data Breach Notification

4.1: Timeline for reporting a breach

Under the GDPR, controllers and processors have an obligation to report a personal data breach to the supervisory authority without undue delay and, where feasible, within 72 hours of becoming aware of the breach. This narrow timeframe emphasizes the importance of swift action and prompt reporting.

The clock starts ticking from the moment the controller or processor becomes aware of the breach. This means that organizations must have mechanisms in place to ensure timely detection and response to potential breaches.

It is also important to note that the notification should still be made even if the full extent of the breach or the impacted individuals is not yet known. Early reporting is key to providing the supervisory authority with an opportunity to take any necessary actions.

4.2: Assessing risk to data subjects

When reporting a personal data breach, a risk assessment must be conducted to determine the potential risks posed to the rights and freedoms of the individuals whose data has been compromised. This assessment helps organizations and supervisory authorities understand the severity of the breach and the actions required to mitigate the risks.

The risk assessment should take into consideration various factors, including the type and sensitivity of the data compromised, the potential consequences for the individuals involved, and any measures in place to protect the data. Factors such as the likelihood of the data being misused or the harm that may arise from the breach should also be considered.

The purpose of this risk assessment is to inform the supervisory authority and affected individuals about the potential risks. It helps determine whether additional steps, such as notifying the individuals or implementing additional security measures, are necessary.

By assessing the risks, organizations can demonstrate their accountability and commitment to protecting personal data. Conclusion:

Personal data breach notifications are a critical aspect of GDPR compliance.

Controllers and processors need to understand the required information to be included in such notifications, as well as the timeline for reporting and risk assessment.
