ABSTRACT

Gateway Servers for the IoT and the Internet of Vehicles (IoV) must meet stringent Security and Quality of Service (QoS) requirements, including cyberattack protection, low delays and low packet loss, to offer secure real-time data exchange for human and vehicle safety, and efficient road traffic management. Therefore, it is vital to protect these systems from cyberattacks with adequate Attack Detection (AD) and Mitigation. Such attacks often also include packet Floods that impair QoS of the networks and Gateways, and even impede the Gateways' capability to carry out AD. Thus, this paper first evaluates these effects using system measurements during Flood attacks. It then shows how a Smart Quasi-Deterministic Policy Forwarder (SQF) at the entrance of the Gateway can regulate the incoming traffic to ensure that the Gateway supports the AD to operate in a timely manner during an attack. Since Flood attacks also create substantial packet backlogs, we also propose a novel Adaptive Attack Mitigation (AAM) system that is activated after an attack is detected, to dynamically sample the incoming packet stream and determine whether the attack is continuing, and also drop batches of packets at the input to reduce the effects of the attack. The AAM is designed to minimize a cost function that includes the sampling overhead, and the cost of lost benign packets. We show experimentally that the Optimum AAM approach is effective in mitigating attacks, and present theoretical and experimental results that validate the proposed approach.
