AgentShield: Deception-Based Compromise Detection for Tool-Using LLM Agents

Defenses against indirect prompt injection IPI in tool-using LLM agents share two structural weaknesses. First, they all attempt to prevent attacks rather than detect the compromises that slip through. Second, they have only been evaluated in English, leaving users of low-resource languages such ...

A Multi-Layered Embedded Intrusion Detection Framework for Programmable Logic Controllers

Industrial control system ICS operations use trusted endpoints like human machine interfaces HMIs and workstations to relay commands to programmable logic controllers PLCs. Because most PLCs lack layered defenses, compromise of a trusted endpoint can drive unsafe actuator commands and risk...
