Four High-Risk Scenarios Covered

1️⃣ Impossible Travel

Trigger: Same user from 2 locations impossible distance/time apart
Response: Step-up challenge → Selective token revoke → Full session kill
Example: Login from New York, 10 minutes later from Tokyo

2️⃣ 2FA Bypass Attempts

Trigger: 5+ failed 2FA attempts in 1 hour
Response: Challenge → Escalation → Account suspend
Example: Attacker trying 6 different codes

3️⃣ Unusual Privilege Action

Trigger: Privilege-sensitive action unusual for user
Response: Requires approval → Enhanced logging → Action blocked if denied
Example: Bulk export of financial data by support staff

4️⃣ Multi-Account Campaign

Trigger: 3+ accounts compromised from same IP
Response: Full session kill → IP blacklist → Geo lock
Example: Botnet attacking 5 of your accounts

12 Security Actions Implemented

#	Action	Stage	Effect	Recovery
1	STEP_UP_CHALLENGE	1	Verify with OTP	User authenticates
2	SELECTIVE_TOKEN_REVOKE	1	Kill suspicious sessions	Forces re-login
3	FULL_SESSION_KILL	2	Terminate all sessions	Re-authentication required
4	FORCE_PASSWORD_RESET	2	Credential reset	User creates new password
5	USER_NOTIFICATION	1	Alert user	Awareness + escalation
6	ANALYST_ESCALATION	3	Route to human	Manual investigation
7	ACCOUNT_SUSPEND	3	Disable account	Manual restoration
8	DEVICE_DEREGISTER	2	Require device re-enrollment	Device verification
9	IPWHITELIST_ADD	1	Add trusted IP	Future convenient access
10	IPBLACKLIST_ADD	3	Block attacker IP	Blocks future attacks
11	GEO_LOCK	3	Geographic restrictions	Location-based access
12	CUSTOM_WEBHOOK	Any	Call external system	Integration flexibility

Quick Start (3 Steps)

Step 1: Verify Installation

# Check all files in place
ls models/IncidentPlaybook.js
ls services/playbooks/incidentPlaybookEngineService.js
ls routes/incidentPlaybooks.js

Step 2: Start Server

npm start
# Server runs on http://localhost:3000

Step 3: Test API

# List playbooks (empty initially)
curl http://localhost:3000/api/incident-playbooks

# Response:
