Handling Data Breaches Under EU GDPR: A Step-by-Step Guide

Data breaches are an unfortunate reality in today's digital landscape. When a breach involves the personal data of EU residents, the EU's General Data Protection Regulation (GDPR) comes into play. This means strict reporting timelines, potential fines, and reputational harm. Let's break down how to respond effectively to a personal data breach within the GDPR framework.


Key Roles and Responsibilities

  • Security Incident Team: Reports the suspected breach immediately to the Data Protection Officer (DPO).
  • Data Protection Officer (DPO): Assesses the risk to individuals' rights and freedoms. Notifies the Data Protection Authority (DPA) and, if necessary, the affected individuals. Collaborates with the organization's public relations team for communication.
  • Processor's DPO: Notifies the controller of the breach as per the terms of their contract.

Action Plan for Data Breach Response

  1. Inform the DPO: Immediate notification is crucial upon discovery of a breach.
  2. Assess Scope and Impact: Quickly determine:
    • Confirmation of personal data breach
    • Estimated number of individuals affected
    • Types of data compromised
    • Existing security measures in place
  3. Notify Relevant Parties:
    • Controller's DPO: Notifies the DPA within 72 hours if the risk to individuals is high. Notifies affected individuals if necessary.
    • Processor's DPO: Notifies the controller promptly.
    • Notifications should include: DPO contact details, breach description, likely consequences, and actions taken/proposed.
  4. Containment and Further Investigation: While notifications are underway, work to:
    • Mitigate the breach and prevent further unauthorized access.
    • Refine the scope of the breach, including the number of individuals and types of data exposed. Update relevant parties as needed.
  5. Review and Monitor: Once the breach is contained, thoroughly review existing security measures. Identify and implement improvements to prevent future incidents. Maintain thorough documentation throughout.

Proactive Preparation is Key

The financial and reputational damage from data breaches can be severe. Don't wait for a crisis – establish a robust data breach response plan and notification templates in advance.

Navigating the Cloud: Cybersecurity Risks and Best Practices

Cloud computing has revolutionized business operations with its scalability, flexibility, and cost efficiency. However, this transformative technology also introduces unique cybersecurity risks that businesses must proactively address to safeguard their valuable data and systems. Understanding Cloud Security Threats Data Breaches: Cloud environments, like any data storage, are vulnerable to breaches due to misconfigurations, application vulnerabilities, or compromised credentials. Unauthorized Access: Inadequate access controls can allow unauthorized individuals to access, modify, or delete sensitive data. Shared responsibility models can sometimes cause confusion about who is accountable for securing specific aspects of the cloud environment. Insecure APIs: Application Programming Interfaces (APIs), essential for cloud services, can become entry points for attackers to exploit vulnerabilities and access sensitive data if not properly secured.

EDPB provides input on biometric use in airports

 The French Supervisory Authority has sought the European Data Protection Board's opinion on the use of facial recognition technology by airport operators and airline companies for biometric authentication of passengers, with the objective of enhancing passenger flow at airports. The Board underscores that the use of biometric data, particularly facial recognition technology, poses significant risks to the rights and freedoms of individuals. This data type is given special protection under Article 9 of the GDPR. Prior to implementing such technologies, controllers are strongly advised to thoroughly evaluate the impact on individuals' fundamental rights and freedoms, and to consider if less invasive methods can achieve the intended purpose. The focus of this opinion is on the compatibility of the processing with specific articles of the GDPR, with the aim of streamlining passenger flow at airports at security checkpoints, baggage drop-off, boarding, and access to passenger loung...
