• Unauthorised access
• Disclosure of personal data
• Alteration of data
• Loss or destruction
Sources of breach
• Cyber attacks
• Insider actions
• System failures
• Vendor incidents

• Notify the Data Protection Board
• Inform affected individuals

Incident Response Framework
Roles
• IT Security for detection and containment
• Privacy and Legal for assessment and notification
• Business teams for impact management
• Communications for external messaging
Controls
• Incident response playbooks
• Escalation matrix
• Communication templates
• Decision authority
Vendor and Third Party Breach Risk
Risks
• Delayed reporting by vendors
• Limited visibility into vendor systems
• Cross-border complexity
Controls
• Contractual notification clauses
• Defined reporting timelines
• Audit rights
Linkage with Retention and Consent
Retention
• More retained data increases breach impact
Refer Data Retention under DPDP
Consent
• Unauthorised processing increases exposure
Refer Consent Management under DPDA
Logging and Monitoring
Minimum requirements
• System activity logs
• Monitoring dashboards
• Alerting mechanisms
• Forensic readiness
Lack of logs makes breach assessment non-defensible
Common Failures
• No clear breach definition
• Delayed detection
• No escalation clarity
• No predefined notification workflow
• Vendor incidents not tracked
These gaps weaken compliance readiness
Executive View
Data breach management impacts
• Regulatory exposure
• Reputation
• Financial loss
