Agent Security Is a Systems Problem Researchers argue that AI agent security must be treated as a systems-level problem, with the AI model itself considered an untrusted component and security invariants enforced at the system level rather than through model robustness alone. The team, drawing on expertise in operating systems, networks, formal methods, and adversarial machine learning, analyzed 11 real-world attacks on agents to demonstrate how established systems security principles could have prevented those breaches. The findings identify key research challenges for implementing these principles in agentic systems.

Through this lens, efforts to increase model robustness the dominant viewpoint in the community are insufficient on their own. Instead, we must complement existing efforts with techniques from the systems security domain. Based on our experience as cybersecurity researchers in operating systems, networks, formal methods, and adversarial machine learning, we articulate a set of core principles, grounded in decades of systems security research, that provide a foundation for designing agentic systems with predictable guarantees. As evidence, we analyze eleven representative real-world attacks on agents and discuss how systems principles, if realized, could have prevented these attacks. We also identify the research challenges that stand in the way of implementing these principles in agents.
