Agent-Native Immune System: a taxonomy and architecture for defending autonomous agents

arXiv·medium signalXBlueskyLinkedInCopy link

An arXiv paper proposes an 'Agent-Native Immune System' — an architecture, taxonomy, and engineering treatment for defending agents equipped with persistent memory, tool-use protocols, and multi-agent collaboration. It frames defense as a continuously adapting layer modeled on biological immunity rather than static guardrails, aligning with the OWASP finding that payload filtering alone fails. Useful conceptual scaffolding for teams building runtime monitoring and anomaly response around agent fleets.
