Digital Personal Data Protection Act · Control IR-002 · Priority: critical · Component: Incident Response

### What this control covers

Implement a data subject breach notification procedure including: (i) pre-approved communication template compliant with Rule 7 (nature of breach, potential impact, mitigation steps, contact for queries); (ii) automated notification trigger linked to breach detection systems; (iii) notification mechanism documentation (email, SMS, in-app); (iv) timeline tracking from breach detection to data subject notification; (v) delivery confirmation logs. Objective: Ensure affected data principals are notified promptly and comprehensively upon a personal data breach, enabling them to take protective action.

### Why it matters

How quickly and methodically you contain an incident determines the regulatory consequence — most fines are not for the breach itself but for the slow or absent response.

### How to implement

#### AWS

Wire **GuardDuty**, **Security Hub** and **Macie** findings into your ticketing/SIEM via EventBridge. Maintain documented playbooks for IAM-key compromise, EC2 instance compromise, S3 data exposure, and run **quarterly tabletop exercises**.

#### Azure

Use **Defender for Cloud** + **Microsoft Sentinel** with playbooks (Logic Apps) for automated containment — disable user, isolate VM (NSG), revoke session tokens. Keep an on-call rotation in Teams with PagerDuty.

#### GCP

Use **Cloud KMS** with customer-managed encryption keys (CMEK) for BigQuery, GCS, and Compute. **Sensitive Data Protection** (DLP API) inspects/de-identifies PII at scale.

#### Google Workspace

Enable **client-side encryption** for Drive/Docs and turn on **Drive Labels + DLP** rules to prevent external sharing of regulated data classes.

#### GitHub

Subscribe to **secret-scanning** alerts and **Dependabot** security advisories; require triage SLAs by severity. For exposed secrets, rotate at the cloud provider FIRST then revoke at GitHub — order matters.

### Evidence to collect

-   `ticketing_workflow` — See the iCompaas Evidence library for the canonical source for this evidence type.
-   `policy_document` — A signed, version-controlled policy stating leadership intent and the named owner.

Signed policies, procedures, and registers document the safeguard. Service management or grievance ticketing records prove timely handling. Focus: Personal Data Breach - Data Subject Notification.
