Multi-Agentic System Threat Modeling

Conduct comprehensive threat modeling for multi-agent systems using the Cloud Security Alliance (CSA) MAESTRO framework's 7-layer architecture and OWASP Multi-Agentic System Threat Modeling Guide v1.0.

Steps

1. MAESTRO 7-Layer Architecture Mapping — Decompose the system into CSA's layered reference architecture:

   • Layer 7: Agent Ecosystem — User-facing applications, agent marketplace, business integrations
   • Layer 6: Security & Compliance — Cross-cutting security controls, compliance frameworks
   • Layer 5: Evaluation & Observability — Monitoring, metrics, anomaly detection, performance tracking
   • Layer 4: Deployment & Infrastructure — Containers, orchestration, cloud/on-premise resources
   • Layer 3: Agent Frameworks — Orchestration logic, agent-tool bindings, routing decisions
   • Layer 2: Data Operations — Memory stores, vector databases, RAG pipelines, context management
   • Layer 1: Foundation Models — Core LLMs, model APIs, inference engines

2. Layer-Specific Threat Analysis — Identify threats unique to each MAESTRO layer using CSA taxonomy.

3. Cross-Layer Threat Assessment — Analyze attack chains that span multiple layers (supply chain attacks, lateral movement, privilege escalation, data leakage cascades).
