Core DPDP Breach Notification Requirements

To comply with DPDP breach notification rules, organizations must:

1. Detect the Breach Promptly

Organizations must have:

• Monitoring and logging systems
• Incident detection tools
• Internal reporting workflows

Detection speed directly impacts regulatory exposure.

2. Assess Severity of the Breach

Evaluate:

• Nature of compromised data
• Volume of affected data
• Sensitivity of information
• Potential harm to individuals

Severity assessment aligns with broader DPDP compliance framework standards.

3. Notify the Data Protection Board

Notification should include:

• Nature of breach
• Data categories affected
• Estimated number of data principals impacted

Transparency is critical for regulatory cooperation.

4. Notify Affected Data Principals

Affected individuals must be informed if the breach poses significant risk.

Notification should clearly explain:

• Organization’s mitigation steps

Clear communication reduces reputational damage.

5. Implement Corrective Measures

After notification, organizations must:

• Contain the breach

Failure to implement corrective action may worsen penalties.
