CrossCheck: Input Validation for WAN Control Systems

This collection of recent papers covers network control, monitoring, ML systems, time sync, and automotive testbeds with clear operational-security implications. CrossCheck proposes a shadow validation system for SDN WAN controllers that detects invalid/buggy controller inputs to prevent outages and tolerates noisy/corrupt telemetry. vLLM Semantic Router describes composable, signal-driven request routing across heterogeneous LLM backends with built-in privacy/safety plugin chains (PII filtering, jailbreak detection, hallucination checks) — relevant to data governance and misrouting risks.
