• Data breach involving client financial data
• Complete system outage during trading hours
• Regulatory compliance violation

High (P1)

• Suspected unauthorized access
• Malware detection on trading systems
• Abnormal trading patterns
• API security breach
• Multi-factor authentication bypass

Medium (P2)

• Failed authentication attempts exceeding thresholds
• Suspicious network activity
• Configuration drift detection
• Certificate expiration warnings
• Rate limiting triggers

Low (P3)

• Information gathering attempts
• Non-critical service disruptions
• Security scanning activities
• Log analysis anomalies

Response Team Structure

Primary Response Team

• Incident Commander: Security Team Lead
• Technical Lead: Senior Platform Engineer
• Compliance Officer: Chief Compliance Officer
• Communications Lead: Head of Operations

Extended Response Team

• Legal Counsel: For regulatory and legal implications
