DAST: VLM-LLM Framework for Cross-Interface Anomaly Detection in O-RAN

arXiv·low signal

O-RAN's open, multi-vendor interfaces expand the attack and fault surface across standardized boundaries. DAST pairs a vision-language model with an LLM to detect anomalies spanning multiple O-RAN interfaces rather than one in isolation. Niche but a concrete example of multimodal models applied to infrastructure observability. Published 2026-06-04 (cs.CR).
