Tabletop Exercise Script for Incident Response Plan

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

1. IR Plan — current incident response plan, escalation hierarchy, severity classification framework
2. Regulatory profile — applicable frameworks and notification deadlines
3. Org context — industry sector, data holdings (PII, PHI, PCI, IP), crisis roles, prior after-action reports
4. Participant list — attendees with titles and IR Plan roles

Quick Start

1. Extract key elements from provided materials (deadlines, escalation paths, data types, prior gaps)
2. Select threat scenario matched to org risk profile
3. Assign participants to functional groups with role cards
4. Design 4–5 progressive injects testing IR phases and notification triggers
5. Draft facilitation guide with ground rules and timing
6. Build debrief agenda and after-action report framework

Workflow

Step 1 — Document Research

Extract from provided materials before drafting:

Step 2 — Scenario Design

Select a threat scenario matched to org risk profile:

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

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:

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):

1. What worked — effective procedures, coordination, decisions
2. 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
3. Root cause per gap
4. Remediation actions with owner + target date

After-action report sections:

Distribution: participants, executive leadership, board/audit committee, CISO office.

Notification Deadline Reference

Build a quick-reference card for participants:

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

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
