Structured analysis of hypothetical attack scenarios:

🔍 Scenario 1: Supply Chain Compromise

• What if: A widely-used dependency in our application contains malicious code?
• Attack Path: Dependency → Build Process → Production Deployment → Data Access
• Impact: Code injection, data exfiltration, service disruption
• Detection: SBOM analysis, dependency scanning, behavioral monitoring
• Response: Dependency isolation, rollback procedures, forensic analysis

🔍 Scenario 2: Cloud Provider Incident

• What if: Our cloud provider experiences a major security incident?
• Attack Path: Cloud Provider → Shared Infrastructure → Customer Data
• Impact: Data exposure, service disruption, compliance violation
• Detection: Provider notifications, anomaly detection, access monitoring
• Response: Data encryption verification, incident coordination, customer communication

🔍 Scenario 3: Insider Threat Escalation

• What if: A trusted employee becomes malicious or is compromised?
• Attack Path: Legitimate Access → Privilege Abuse → Data Theft
• Impact: Data exfiltration, system sabotage, competitive intelligence theft
• Detection: Behavioral analytics, access monitoring, data classification
• Response: Access revocation, forensic investigation, legal coordination

Integrating threat modeling with business impact quantification:

Threat Scenario	Probability	Financial Impact	Operational Impact	Reputation Impact	Total Risk Score
🔐 Customer Data Breach	15%	€500K-2M			9.2/10
🎮 Gaming Platform Disruption	25%	€50K-200K			6.8/10
🧠 Source Code Theft	10%	€200K-1M			7.5/10
☁️ Cloud Infrastructure Compromise	20%	€100K-500K			7.1/10
