🔄 Incident Response Process¶

Phase 1: Detection & Alerting (0-15 minutes)¶

Automated Detection Sources¶

Security audit logs (/tmp/security-audit.log)
Query complexity analyzer alerts
Circuit breaker state changes
Authentication failure patterns
Cross-tenant access attempts
Rate limiting violations

Manual Detection Sources¶

Customer reports
Security researcher notifications
Third-party security alerts
Monitoring dashboard anomalies

Initial Response Actions¶

# 1. Acknowledge the alert
curl -X POST http://localhost:4009/api/incident/acknowledge \
  -H "Content-Type: application/json" \
  -d '{"incidentId": "INC-2025-001", "acknowledgedBy": "analyst@company.com"}'

# 2. Gather initial context
tail -f /tmp/security-audit.log | grep -E "(CRITICAL|HIGH_RISK)"

# 3. Check system health
make monitor-startup
curl http://localhost:4004/search/circuit-breakers

Phase 2: Initial Assessment (15-45 minutes)¶

Security Triage Checklist¶

Threat Validation: Confirm if threat is genuine or false positive
Impact Assessment: Determine affected systems, users, and data
Scope Analysis: Identify if incident is isolated or part of larger campaign
Timeline Establishment: Determine when incident started
Evidence Preservation: Secure logs and forensic artifacts

Key Investigation Queries¶

# Check authentication events for specific user
grep "userId:USER_ID" /tmp/security-audit.log | grep -E "(LOGIN_FAILURE|PRIVILEGE_ESCALATION)"

# Analyze query patterns for anomalies
grep "COMPLEX_QUERY_EXECUTED\|QUERY_BLOCKED" /tmp/security-audit.log | tail -50

# Check cross-tenant access attempts
grep "CROSS_TENANT_ACCESS_ATTEMPT" /tmp/security-audit.log

# Review API key usage patterns
grep "API_KEY_INVALID\|API_KEY_EXPIRED" /tmp/security-audit.log

Risk Assessment Matrix¶

Impact	Likelihood	Risk Level	Response
High	High	Critical	Immediate containment
High	Medium	High	Rapid response
Medium	High	High	Rapid response
Medium	Medium	Medium	Standard response
Low	Any	Low	Monitor and document

Phase 3: Containment (45 minutes - 2 hours)¶

Immediate Containment Actions¶

For Authentication Compromise:

# Disable compromised user account
curl -X POST http://localhost:4006/api/users/disable \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"userId": "COMPROMISED_USER_ID", "reason": "Security incident"}'

# Revoke all sessions for user
curl -X POST http://localhost:4006/api/sessions/revoke-all \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"userId": "COMPROMISED_USER_ID"}'

# Blacklist suspicious IP addresses
curl -X POST http://localhost:4006/api/security/blacklist-ip \
  -d '{"ipAddress": "SUSPICIOUS_IP", "reason": "Security incident", "duration": "24h"}'

For Query-Based Attacks:

# Enable emergency query restrictions
curl -X POST http://localhost:4004/api/security/emergency-mode \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"enabled": true, "restrictions": {"maxComplexity": 25, "maxRows": 1000}}'

# Block specific organization if cross-tenant attack
curl -X POST http://localhost:4004/api/security/block-organization \
  -d '{"organizationId": "ORG_ID", "reason": "Security incident"}'

For System Compromise:

# Isolate affected services
docker-compose stop suspicious-service

# Enable enhanced monitoring
export SECURITY_ALERT_LEVEL=HIGH
make monitor-continuous

Short-term Containment¶
