The GDPR (General Data Protection Regulation) has strict data breach response requirements, particularly for ransomware attacks that affect personal data. The appropriate next step after an internal investigation is to assess the risks associated with the breach and notify affected parties if necessary.

Key GDPR Breach Response Steps (Article 33 & 34):

Assess the risks to personal data

If the breach poses a risk to individuals' rights and freedoms, the supervisory authority (DPA) must be notified within 72 hours.

If there is a high risk, affected individuals must also be informed without undue delay.

Why Answer Choice A is Correct

Risk assessment is a critical first step after an internal investigation.

If the breach meets the risk threshold, notification to authorities and individuals is required under GDPR.

Why Other Answer Choices Are Incorrect:

B (Notify Law Enforcement First): While law enforcement may be involved, GDPR does not mandate consulting law enforcement before conducting a risk assessment or notifying individuals.

C (Informing the Public Immediately): Public disclosure via social media is not a GDPR requirement. Affected individuals and DPAs should be formally notified first.

D (Waiting for Law Enforcement): GDPR does not allow waiting for law enforcement before fulfilling notification obligations. Controllers must act within 72 hours.

Conclusion: The correct next step after an internal investigation is to assess the risks and, if necessary, notify affected individuals and regulatory bodies as required under GDPR Articles 33 and 34.
