Hybrid Hierarchical Runtime Verification for Edge-IoT Security: Combining MonPoly and RTLola
Nikolaos Kekatos, Marinelio Chintri, Panagiotis Katsaros +5
Security monitoring of edge-IoT fleets faces three structural challenges. (i) A per-node monitor is cheap but cannot see attacks that coordinate across devices. (ii) A cloud monito…
Formal Runtime Verification for Tool-Using LLM Agents: An Offline Same-Benchmark Study on AgentDojo and STAC
Nikolaos Kekatos, Stylianos Basagiannis, Marinelio Chintri +5
Guardrails for tool-using LLM agents are usually application-specific rules, which makes multi-step, data-dependent safety policies hard to specify, audit and reuse. As a declarati…
A Resilient Runtime-Verification Fabric for Security Monitoring of Critical Edge-IoT Infrastructure
Nikolaos Kekatos, Marinelio Chintri, Panagiotis Katsaros +5
Protecting critical infrastructure increasingly depends on continuously verifying large IoT fleets against formal security specifications at runtime. Yet the runtime-verification (…
