The General Data Protection Regulation (GDPR) demands strict standards for organizations that handle personal data, especially regarding data breach incidents. The most critical duty GDPR states demands prompt security incident responses and immediate notification to affected parties. Non-compliance with GDPR standards results in heavy financial penalties while causing significant harm to a business's reputation. The GDPR breach notification guide includes information about the requirements for reporting such incidents while showing who requires notification and providing effective compliance strategies.

Understanding Breach Notification Under GDPR

A personal data breach under GDPR refers to any security incident that results in accidental or unlawful destruction, loss, alteration, unauthorized disclosure, or access to personal data (Article 4(12) GDPR). Simply, if personal data is leaked, modified, lost, or accessed without permission, it qualifies as a breach. GDPR classifies breaches into three main types:

• Confidentiality Breach: This happens when personal data is accessed or shared without authorization. For example, if a hacker gains access to customer records or an employee mistakenly sends sensitive information to the wrong recipient, it falls under this category.

• Integrity Breach: This occurs when personal data is altered without permission. Cybercriminals modifying customer records or making unauthorized changes to a database that affect the accuracy of stored data are examples of integrity breaches.

• Availability Breach: This happens when personal data is lost or becomes inaccessible. Scenarios include data being deleted accidentally, a ransomware attack locking access to files, or system failures that lead to lost data.

The 72-Hour Rule

An organization must tell the controlling GDPR authority about data breaches within 72 hours following a breach discovery unless the incident poses no risk to personal rights or freedoms. The notification should include:

• The type and nature of the breach.

• The categories and estimated number of affected individuals and records.

• The possible consequences of the breach.

• The measures taken or planned to mitigate risks and prevent further breaches.

• The contact details of the Data Protection Officer (DPO) or relevant representative.

Organizations must justify the delay if they fail to notify the regulatory authority within this period.

Who Needs to Be Notified?

Affected Individuals

Organizations need to immediately notify people affected whenever a breach threatens their rights and freedoms. The notification enables the affected persons to implement protective measures that might involve password changes, fraudulent activity monitoring, and legal procedures.

Data Processors vs. Controllers

• Data Controllers must follow two notification requirements for DPA and the affected persons.

• Data processors need immediate notification from the data controller to take the required measures.

Penalties for Non-compliance

Failure to comply with GDPR's breach notification rules can result in heavy fines under Article 83 GDPR:

• Up to €10 million or 2% of global annual turnover (whichever is higher) for failing to notify a breach.

• Up to €20 million or 4% of global annual turnover for severe violations, including failure to implement security measures.

Examples of GDPR Breach Notifications

The General Data Protection Regulation (GDPR) mandates strict guidelines for data protection. The law demands that organizations alert affected individuals and authorities following any data breach. These are several significant instances of breach notifications.

Marriott Data Breach (2018)

Marriott International experienced a data breach which exposed passport numbers and payment details among the records of 500 million guest accounts. A €20 million fine was imposed on the company due to its delayed response to the breach notification. Both the authorities and customers received information about the incident from the company.

Uber Data Breach (2016)

The cyberattack of 57 million Uber customers led to a cover-up attempt through an extortion payment to maintain silence from the hackers. The delayed reporting of authorities about security breaches cost Uber significant fines alongside severe damage to its reputation because of the GDPR framework.

Equifax Data Breach (2017)

Equifax suffered a security incident that impacted millions of users everywhere, particularly those residing within the EU. European authorities enforced GDPR against the company when Uber waited too long to notify regulators and customers about the incident.
