Situation & objectives
I would deliver an incident response (IR) plan that simultaneously meets GDPR (72-hour), HIPAA, and PCI-DSS obligations while minimizing cross‑border legal risk and preserving forensic evidence for regulatory and potential legal proceedings.
High-level sequencing & notifications
- Triage (0–4 hrs): Activate IR team, isolate affected systems, preserve volatile data. Log chain-of-custody start.
- Contain & assess (4–24 hrs): Rapid scoping to classify data types (EU personal data, US PHI, cardholder data), estimate records impacted, and determine ongoing risk to individuals.
- Regulatory decisioning (24–48 hrs): Convene legal, privacy, compliance to map obligations:
- GDPR: prepare breach notification draft to supervisory authority within 72 hours from detection; include nature, categories, estimated numbers, mitigation.
- HIPAA: notify HHS OCR and affected individuals “without unreasonable delay” and no later than 60 days if breach confirmed; expedite if high risk.
- PCI-DSS: notify acquirer and card brands immediately per card-scheme timelines; engage PCI QSA and card forensics vendor.
- Public/customer notifications (after regulator coordination): Sequence notifications to regulators first where required; coordinate joint messaging to avoid conflicting statements and to control cross-border legal risk.
Forensic requirements & evidence preservation
- Preserve disk images, memory captures, network logs, SIEM, WAF/IDS, VPN logs, and cloud audit trails; record hash values and chain-of-custody metadata.
- Use dedicated, hardened forensic collectors and retain original media offline. Avoid changing timestamps or modifying evidence.
- Engage independent forensic investigators (PCI‑approved for card data) early; maintain segregation of duties between investigators and remediation teams.
Cross-border legal risk mitigation
- Consult Data Protection Officer and external counsel in EU and US immediately to assess GDPR supervisory authority interaction, potential DPA notifications, and transfer/legal process for PHI.
- Limit international data transfers of breach data; use secure channels and need‑to‑know. Consider freezing exports pending legal advice.
Deliverables & metrics
- 72‑hour GDPR report ready for regulator with documented detection timeline.
- HIPAA risk assessment and notification plan within 7 days.
- PCI forensic report and containment evidence as per card schemes.
- Evidence log, forensic report, root-cause, remediation roadmap, and post‑incident review within 30 days.
This plan balances timely regulatory notification, rigorous forensics, and legal risk controls appropriate for an enterprise security architecture role.
