Researchers have developed MESA, a novel framework designed to proactively identify and prioritize the most vulnerable communication channels within multi-agent systems (MAS). This approach aims to optimize limited security resources by focusing on critical edges that, if compromised, could significantly impact the system's overall success. MESA utilizes a combination of graph-theoretic metrics and dynamic probes, without requiring prior attack data, to rank these critical edges. Evaluations across diverse MAS scenarios and LLMs demonstrated that MESA's rankings strongly correlate with actual attack success rates, enabling defenders to intercept substantially more attacks compared to random allocation.
