CSCM88 Network and Wireless Security

Low cost networked computers add eyes and ears (or sensors) and arms, legs and voices (or actuators) to the Internet ¿ called the Internet of Things (IoT) connected smart objects. Networking technologies play a critical role in almost all modern software-based systems, whether the fixed networks of computers, or the growing pervasive devices which have increasingly diverse profiles of network connectivity. As a result, they provide a potential vector for many forms of attack and are an ideal location for many threat mitigations and isolation technologies.
