CCSP Practice Question: A cloud provider experiences a data breach…
A cloud provider experiences a data breach affecting customer data. Which of the following laws most likely requires the provider to notify affected customers within 72 hours?
⚠ Common exam trap
ISC2 often tests the distinction between regulatory laws (like GDPR) and industry standards or frameworks (like PCI DSS), causing candidates to mistakenly select PCI DSS because it is commonly associated with data security, even though it is not a law and lacks a 72-hour notification requirement.

Correct answer & explanation
✓
GDPR
The GDPR (General Data Protection Regulation) explicitly requires data controllers to notify the relevant supervisory authority of a personal data breach within 72 hours of becoming aware of it, and to communicate the breach to affected data subjects without undue delay if it poses a high risk to their rights and freedoms. This 72-hour notification mandate is unique to GDPR among the listed options, making it the correct answer for a cloud provider experiencing a data breach affecting customer data.
