NOW: Stop the Bleeding — 72-Hour INCIDENT RESPONSE PROTOCOL (Act Immediately)

This is an emergency. Every minute matters. You have 72 hours before a breach escalates into board-level catastrophe. Follow this protocol — no debate, no delay. Use counsel for legal steps, but execute containment and evidence preservation immediately.

Hour 1: Critical Actions

1. Declare an incident: Activate the Incident Response (IR) playbook and war room (virtual and physical). Notify CISO, IR Lead, SOC Manager, Legal, Communications, Privacy, CTO, and CFO.
2. Isolate without destroying evidence: Segment affected systems from the network (ACLs, VLAN quarantines). Do not reboot forensic targets unless instructed.
3. Preserve logs and snapshots: Collect disk images, EDR telemetry, SIEM logs, identity provider logs, cloud audit trails, and backup integrity checks. Start chain-of-custody.
4. Engage external forensics and breach counsel: Trigger pre-contracted DFIR and legal retainer. If none, call top-ranked responders now.
5. Start internal comms: One senior communications lead to coordinate all statements. No ad-hoc messages to employees, customers, or press.

Hour 4: Triage & Containment

1. Assign asset owners to confirm compromise scope. Prioritize domain controllers, identity stores, cloud admin accounts, backup systems, crown-jewel data stores (PII/IP/financial).
2. Reset high-risk credentials (privileged accounts) with multi-party approval. Enforce emergency MFA reset for affected users.
3. Apply targeted containment rules in EDR/XDR, firewall NGFW policies, and cloud security](https://steelefortress.com/fortress-feed/the-myth-of-crypto-laws-protecting-clients-why-regulations-are-making-lawyers-more-liable-not-safer)](https://steelefortress.com/fortress-feed/protecting-your-law-firm-from-digital-threats-my-guest-appearance-on-counsel-cast-podcast)](https://steelefortress.com/fortress-feed/lock-it-down-the-ultimate-playbook-to-freeze-protect-and-secure-your-credit-like-a-pro)](https://steelefortress.com/fortress-feed/just-discovered-2025-update-how-one-thirdparty-vendor-breach-is-silently-crippling-major-networks-right-now) controls (disable compromised API keys, rotate secrets).
4. Activate legal notification timeline: Determine materiality; prepare to file SEC Form 8-K if material. SEC rule: report material cybersecurity incidents within 4 business days once materiality is determined. See SEC guidance: SEC cybersecurity.

Hour 12: Evidence & Decisioning

1. Complete initial forensics report: TTPs, suspected threat actor, initial entry vector, lateral movement. Use MITRE ATT&CK mapping: MITRE ATT&CK.
2. Lock down exfil channels: Block known C2 domains/IPs, monitor outbound traffic, and throttle data egress to critical locations.

Safeguarding Data

Hour 24: Damage Control

1. Public & regulator notification draft: Prepare statements for regulators (SEC, GDPR DPA, HIPAA OCR, state attorneys general) and customers. GDPR requires notification to the supervisory authority within 72 hours of becoming aware of a personal data breach.
2. Run accelerated vulnerability assessment of environment and patch critical vulnerabilities discovered during forensics.
3. Start customer communications plan — factual, non-speculative, and PSR-approved. Prepare FAQs and a hotline.
4. Finalize containment: rebuild hardened systems from known-good images where necessary. Do not reconnect until validated.

Hour 48: Escalation & Regulatory Compliance

1. Confirm regulator filing obligations:
   • SEC: material cyber incident reporting (Form 8-K) within 4 business days.
   • GDPR: 72-hour personal data breach notification.
   • HIPAA OCR: 60-day breach notification to HHS for covered entities.
   • PCI DSS: notify acquirer/card brands immediately and follow forensic requirements per card brand rules.
   • NYDFS & sector-specific regulations: confirm timelines with counsel; many expect notification within 24–72 hours.
2. Decide: reclaim, ransom negotiate, or rebuild. Consult counsel and law enforcement. Never pay without board sign-off and legal approval.

Hour 72: Recovery & Reporting

1. Execute phased recovery: restore validated backups to segmented environment, validate integrity, and escalate to production only after full testing.
2. Complete post-incident report for Board and regulators: root cause, impact, containment timeline, residual risk, remediation plan, and FY+1 budget ask.
3. Trigger third-party notices and contractual obligations; begin credit monitoring and remediation offers to affected parties if required.
4. Begin lessons-learned retro and update IR playbook immediately.

Immediate KPIs & Dashboard (Board-ready)
