Network-Level Security for the Internet of Things: Opportunities and Challenges

Smart environments with many Internet of Things (IoT) devices are at significant risk of cyberattacks, putting private data and personal safety in danger. While IoT device manufacturers are putting more safeguards in their products, they need to be augmented with networklevel methods to detect and block anomalous behavior. Our approach provides a strong layer of runtime defense at the network layer applicable to large and heterogeneous IoT environments.
