This module provides a foundational understanding of multi-agent system (MAS) architectures. You will learn how autonomous agents collaborate, share state, and delegate tasks. By mapping the communication pathways and shared memory spaces, you will identify the unique attack surfaces introduced by agent-to-agent interactions, including cascading failures, indirect prompt injection across agents, and trust boundary violations.
