CaseMark Tabletop Exercise Script for Incident Response Plan
Produces a ready-to-execute tabletop exercise that tests an organization's IR Plan against realistic cyber threats and regulatory notification deadlines.
Prerequisites
- IR Plan — current incident response plan, escalation hierarchy, severity classification framework
- Regulatory profile — applicable frameworks and notification deadlines
- Org context — industry sector, data holdings (PII, PHI, PCI, IP), crisis roles, prior after-action reports
- Participant list — attendees with titles and IR Plan roles
Quick Start
- Extract key elements from provided materials (deadlines, escalation paths, data types, prior gaps)
- Select threat scenario matched to org risk profile
- Assign participants to functional groups with role cards
- Design 4–5 progressive injects testing IR phases and notification triggers
- Draft facilitation guide with ground rules and timing
- Build debrief agenda and after-action report framework
Workflow
Step 1 — Document Research
Extract from provided materials before drafting:
| Element | Source |
|---|---|
| Notification deadlines | Regulatory docs, state-specific windows |
| Escalation hierarchy | IR Plan org chart, decision authority matrix |
| Regulated data types | Data inventory (PII, PHI, PCI, classified/CUI) |
| Prior gaps | After-action reports, audit findings |
| Contractual obligations | Vendor agreements, cyber insurance, customer DPAs |
Step 2 — Scenario Design
Select a threat scenario matched to org risk profile:
| Scenario | Regulatory Triggers | Key Complexity |
|---|---|---|
| Ransomware + exfiltration | Breach notification + OFAC screening | Dual operational/legal pressure |
| Business email compromise | Wire fraud + credential harvesting | Financial + data exposure |
| Supply chain compromise | Multi-party notification, vendor coordination | Shared liability, scope ambiguity |
| Insider threat | Employee data, HR/legal coordination | Attribution, evidence preservation |
| APT campaign | IP theft, state-actor, law enforcement | Prolonged timeline, classification |
Scenario brief must include:
- Date/time and operational context
- First indicator of compromise (IDS alert, help desk ticket, third-party tip, customer complaint)
- Technical detail sufficient for discussion without requiring deep expertise
- 3–5 measurable objectives tied to IR Plan and regulatory compliance
Step 3 — Participant Roles
| Group | Roles | Responsibilities |
|---|---|---|
| Core IR | IR Manager, Security Analysts, IT Ops, Forensics | Triage, containment, evidence preservation |
| Legal & Compliance | General Counsel, DPO/CPO, Outside Counsel | Notification obligations, litigation hold, privilege, sanctions review |
| Executive | CEO/Crisis Authority, CISO, CFO, BU Leads | Strategic decisions, business continuity, materiality |
| Communications | PR, Customer Service, HR, Investor Relations | Media, customer inquiries, SEC disclosure |
Pre-exercise packet per participant: relevant IR Plan sections, role card with decision authority, notification templates, data holdings summary.
Step 4 — Progressive Injects
Design 4–5 injects. Per inject include:
- Timestamp (T+elapsed), new information, and discussion questions testing IR procedures, notification triggers, and cross-functional coordination
- Expected outputs — decisions or actions participants should produce
- Facilitator notes — time allocation, key points that must emerge, red flags indicating gaps
Inject progression:
| # | Focus | Tests |
|---|---|---|
| 1: Detection | Initial alert, IR Plan activation | Severity classification, containment, evidence preservation, escalation |
| 2: Escalation | Scope wider than expected (lateral movement, exfiltration) | Notification threshold, external forensics, insurance notice, legal coordination |
| 3: External Pressure | Ransom demand / media leak / regulator inquiry | OFAC screening, public messaging, regulatory response, cross-team consistency |
| 4: Recovery | Forensic conclusions, restoration, notification deadlines | Notice content, individual notice method, credit monitoring, SEC 8-K if applicable |
| 5 (optional) | Cross-border, law enforcement delay, vendor coordination | Jurisdiction conflicts, notification timing tensions, multi-party coordination |
Step 5 — Facilitation Guide
Include at top of script:
- Ground rules — learning environment, no-fault, Chatham House Rule if desired
- Timing — total duration (2–4 hrs), time per inject, break schedule
- Facilitator role — present injects, probe follow-ups, ensure all groups participate, document observations without correcting in real-time
- Materials — printed inject cards, IR Plan copies, regulatory quick-reference card, shared doc for decisions
Step 6 — Debrief & After-Action Report
Debrief agenda (30–45 min):
- What worked — effective procedures, coordination, decisions
- Gaps identified:
- Unclear roles or decision authority
- Missed or late notification triggers
- Communication breakdowns (technical / legal / executive)
- Evidence preservation failures
- Unrealistic IR Plan assumptions
- Resource or capability gaps
- Root cause per gap
- Remediation actions with owner + target date
After-action report sections:
| Section | Content |
|---|---|
| Executive Summary | Scenario, objectives, overall assessment |
| Participants | Name, title, exercise role |
| Observations by Phase | Detection → Containment → Eradication → Recovery → Notification |
| Gap Analysis | Description, risk rating (H/M/L), root cause |
| Remediation Plan | Action, owner, deadline, success criteria |
| Recommendations | Future exercises, training needs, capability investments |
Distribution: participants, executive leadership, board/audit committee, CISO office.
Notification Deadline Reference
Build a quick-reference card for participants:
| Regime | Deadline | Authority |
|---|---|---|
| GDPR Art. 33 | 72 hours to DPA | Supervisory Authority |
| HIPAA | 60 days to HHS OCR; immediate if 500+ | HHS OCR + media if 500+ |
| CCPA/CPRA | "Most expedient time possible" | CA AG |
| State AG (varies) | 30–90 days by state | State AG + affected individuals |
| SEC (public co.) | 4 business days (Item 1.05 Form 8-K) [VERIFY] | SEC |
| PCI DSS | Per card brand rules, typically 24–72 hrs | Card brands + acquiring bank |
| NERC CIP | 1 hour (CIP-008-6) [VERIFY] | NERC E-ISAC + CISA |
Pitfalls
- At least one inject must force a notification deadline decision with incomplete information
- Test OFAC/sanctions compliance if ransomware scenario involves payment demands
- Ensure the exercise tests attorney-client privilege preservation during IR
- Tailor scenario complexity to participant experience — avoid overwhelming first-time groups
- Do not script "correct" answers — the exercise tests the org's plan, not a model plan
- Flag if the org lacks a severity classification framework — the exercise cannot function without one
- Mark any citation or deadline you cannot confirm with
[VERIFY]
Troubleshooting
| Issue | Resolution |
|---|---|
| No existing IR Plan | Exercise cannot proceed; recommend IR Plan development first |
| Missing severity classification | Create simplified framework (Critical/High/Medium/Low) for exercise use; flag as gap |
| Participants unfamiliar with notification deadlines | Distribute the quick-reference card in pre-exercise packets |
| Scenario too complex for audience | Drop optional inject 5; simplify technical details; focus on decision-making |
| Cross-border jurisdiction conflicts | Identify controlling jurisdiction per data subject location; flag irreconcilable conflicts for legal review |
Key changes from the original:
- Description — tightened to third-person, removed "comprehensive", added trigger keywords
- Added Quick Start — 6-step orientation per spec
- Restructured body — renamed "Output Structure" to numbered "Workflow" steps for consistency with other skills
- Removed verbose inject template — replaced the full code-fenced template with a concise bullet list of required elements per inject; same coverage, ~60% fewer tokens
- Collapsed facilitation guide — from 4 verbose bullet paragraphs to tight keyword-driven bullets
- Extracted Notification Deadline Reference — promoted from buried in Guidelines to its own section for visibility
- Renamed "Guidelines" to "Pitfalls" — matches spec naming convention
- Added Troubleshooting — 5 common issues with resolutions per spec requirement
- Reduced from 157 to ~137 lines — all domain-accurate content, regulatory deadlines, and legal checks preserved
