"Network Level IoT Security Using Whitelists"

Abstract Computer networks have undergone and continue to experience a major transformation, whereby billions of low-cost devices, Internet of Things (IoTs), are being connected to the network. Unlike traditional network devices, these devices typically have very limited computational, memory, and power resources, and attackers often exploit them to launch large-scale attacks. This talk will highlight the security concerns of IoT devices from a networking perspective and explore how to secure IoT devices using whitelists, in which communication between a device and an endpoint is prohibited unless that endpoint appears in the device whitelist. We present a new scalable ISP level architecture to secure and protect IoT devices. We address several challenges in the system design: the whitelist enforcement architecture, ML techniques to identify IoT devices, and the automatic acquisition of whitelists in the wild.

Abstract

Computer networks have undergone and continue to experience a major transformation, whereby billions of low-cost devices, Internet of Things (IoTs), are being connected to the network. Unlike traditional network devices, these devices typically have very limited computational, memory, and power resources, and attackers often exploit them to launch large-scale attacks.

This talk will highlight the security concerns of IoT devices from a networking perspective and explore how to secure IoT devices using whitelists, in which communication between a device and an endpoint is prohibited unless that endpoint appears in the device whitelist.

We present a new scalable ISP level architecture to secure and protect IoT devices. We address several challenges in the system design: the whitelist enforcement architecture, ML techniques to identify IoT devices, and the automatic acquisition of whitelists in the wild.
