Breach notification is governed by various regulations globally, each with its own set of rules regarding when and how organizations should notify affected individuals, regulatory bodies, and other stakeholders. Understanding the regulatory landscape is crucial for organizations to navigate the complex web of requirements.
### A. GDPR (General Data Protection Regulation):
The GDPR, applicable in the European Union, sets strict standards for breach notification. Organizations must notify the appropriate supervisory authority within 72 hours of becoming aware of a breach. Additionally, affected individuals must be informed without undue delay if the breach poses a high risk to their rights and freedoms.
### B. HIPAA (Health Insurance Portability and Accountability Act):
In the healthcare sector in the United States, HIPAA mandates that covered entities notify affected individuals, the Department of Health and Human Services (HHS), and, in some cases, the media of a breach within 60 days of discovery.
### C. Other Jurisdictions:
Different regions and industries may have specific breach notification requirements. For instance, the California Consumer Privacy Act (CCPA) stipulates that businesses must notify affected residents of a breach if it exposes certain personal information.
## II. Critical Events Surrounding a Breach: Short-Term Impacts (First 72 Hours)
Understanding the short-term timespans associated with critical events in the aftermath of a breach is essential for organizations to develop effective incident response plans. This section focuses on the initial 72 hours — a critical window for detection, containment, and initial breach notification.
### A. Detection and Containment (First 72 Hours):
