What Singaporean Businesses Should Do in the First 72 Hours After a Data Breach

In Singapore, the regulatory landscape governed by the Personal Data Protection Commission (PDPC) imposes strict timelines for reporting. Understanding exactly what a Singaporean do first 72 hours framework looks like is essential for any business operating in the region.

• Identify and Contain: Isolate affected systems to prevent further data exfiltration. If a server is compromised, disconnect it from the network but do not power it down, as this may destroy volatile forensic evidence.
• Document Everything: Maintain a chronological log of all actions taken. This will be invaluable for internal reviews and potential regulatory inquiries.
• Assess Scope: Determine what types of data were accessed. Under the PDPA, the notification obligation is triggered if the breach is likely to result in significant harm to individuals or involves the data of 500 or more individuals.

The Regulatory Clock: Hours 24 to 72

Once containment is stabilized, the focus shifts to regulatory compliance and stakeholder communication. The Personal Data Protection Commission (PDPC) mandates that organizations must notify the commission as soon as practicable, and no later than three calendar days after determining a notifiable breach has occurred.
