A Threat Model for Vehicular Fog Computing

Abstract

Vehicular Fog Computing (VFC) facilitates the deployment of distributed, latency-aware services, residing between smart vehicles and cloud services. However, VFC systems are exposed to manifold security threats, putting human life at risk. Knowledge on such threats is scattered and lacks empirical validation. We performed an extensive threat assessment by reviewing literature and conducting expert interviews, leading to a comprehensive threat model with 33 attacks and example security mitigation strategies, among others. We thereby synthesize and extend prior research; provide rich descriptions for threats; and raise awareness of physical attacks that underline importance of the cyber-physical manifestation of VFC.INDEX TERMS Vehicular fog computing, fog computing, threat model, STRIDE, security.

Toward Secure and Trustworthy Vehicular Fog Computing: A Survey

“…In the context of vehicular Fog, deploying fog vehicles as bots to launch many meaningless service requests simultaneously causes more harm than traditional DDoS. As a result, vehicular fog nodes cannot handle many queries simultaneously, and Many services may become unavailable over an extended period [94]. The authors in [95] leverage fog computing to deploy an anomaly detection mechanism closer to IoT devices and edge networks.…”
