Plings Key Compromise Procedures - Incident Response Guide

Created: Sön 13 Jul 2025 11:17:59 CEST
Security Classification: Confidential - Incident Response Team Only
Document Version: 2.0 - Wallet-First Incident Response
Review Schedule: Quarterly (Next: October 2025)

Executive Summary

This document provides comprehensive incident response procedures for cryptographic key compromise scenarios in the Plings wallet-first architecture. The procedures ensure rapid containment, systematic recovery, and complete forensic investigation while maintaining service continuity and customer trust.

Critical Success Factors

1. Speed of Response: First 15 minutes determine incident impact scope
2. Isolation Effectiveness: Prevent lateral movement and additional compromise
3. Recovery Completeness: Ensure no compromised keys remain in production
4. Business Continuity: Maintain service availability during incident response
5. Forensic Integrity: Preserve evidence for investigation and regulatory reporting

Incident Types and Response Times

Incident Type	Response Time	Business Impact	Recovery Complexity
Master Key Compromise	< 15 minutes	Critical	Extreme
Wallet Version Compromise	< 1 hour	High	High
Manufacturer Key Compromise	< 4 hours	Medium	Medium
Path Allocation Attack	< 24 hours	Low	Low

Incident Classification and Escalation

Severity Level Definitions

P0 - Critical (Master Key Compromise)

Definition: Compromise or suspected compromise of the Plings master key stored in HSM
Impact: Complete ecosystem at risk, all wallet versions potentially affected
Response Team: Full incident response team + C-level executives
Communication: Immediate (< 15 minutes) to all stakeholders

Indicators:

• Unauthorized HSM access detected
• Anomalous master key usage patterns
• Multiple wallet versions showing compromise indicators
• HSM tamper alerts or physical security breaches
• Insider threat involving HSM administrators

Business Impact:

• Complete service shutdown required
• All manufacturer relationships affected
• Potential regulatory notification required
• Significant financial and reputational impact

P1 - High (Wallet Version Compromise)

Definition: Compromise of individual wallet version keys or infrastructure
Impact: Single wallet environment affected, other wallets remain secure
Response Team: Security team + operations + affected business units
Communication: Within 1 hour to security team and executive leadership

Indicators:

• Unauthorized identifiers generated within wallet version
• Anomalous path allocation patterns in specific wallet
• Wallet infrastructure compromise detected
• Failed cryptographic verifications for wallet-specific operations

Business Impact:

• Affected wallet version isolation required
• Manufacturer migration to secure wallet version
• Limited service disruption during migration
• Customer communication required

P2 - Medium (Manufacturer Key Compromise)

Definition: Compromise of manufacturer-delegated keys or namespace
Impact: Single manufacturer namespace affected
Response Team: Security team + manufacturer relations + operations
Communication: Within 4 hours to affected parties

Indicators:

• Unauthorized identifier generation for specific manufacturer
• Manufacturer reporting key compromise or suspicious activity
• Anomalous allocation patterns for manufacturer namespace
• Failed manufacturer key verification

Business Impact:

• Manufacturer key revocation and reissuance
• Limited disruption to specific manufacturer operations
• Path migration within secure namespace
• Manufacturer-specific customer communication

P3 - Low (Operational Security Issue)

Definition: Security policy violations or minor compromise indicators
Impact: Potential security weakness without immediate threat
Response Team: Security operations team
Communication: Within 24 hours through normal channels

Indicators:

• Failed authentication attempts above threshold
• Security control configuration issues
• Minor policy violations or procedural failures
• Performance anomalies with potential security implications

P0 Response: Master Key Compromise

Phase 1: Immediate Response (0-15 minutes)

1.1 Emergency Declaration

# Emergency response activation

# Immediate notifications
curl -X POST "${EMERGENCY_WEBHOOK}" \
  -H "Content-Type: application/json" \
