Network Level IoT Protection Lab

Computer networks have undergone and continue to experience a major transformation, whereby billions of low-cost devices are being connected to the network to provide additional functionality and better user experience. Unlike traditional network devices, these devices, collectively known as the "Internet of Things" (IoT), typically have very limited computational, memory, and power resources. These IoT devices became a major security concern, both due to human factors and to technical challenges in deploying security mechanisms on devices with low resources. The number and diversity of IoT devices creates a huge attack surface that is often exploited by attackers to launch large-scale attacks, sometimes exploiting well-known vulnerabilities. Our group talk focus is on the security aspects of IoT devices from a networking perspective.
