Answer:

On becoming aware of a personal data breach, the Data Fiduciary must intimate each affected Data Principal without delay in clear language - describing the breach, the data involved, possible consequences, mitigation measures taken, safety steps the individual can take, and contact details. It must also notify the Data Protection Board without delay, and provide the Board with detailed particulars (facts, mitigation, findings) within 72 hours, or such longer period as the Board may allow on request.
