Security in Wireless Networks

The purpose of this course is to familiarise participants with threats, vulnerabilities, and security countermeasures of existing and upcoming wireless and mobile networks. The covered security topics include a wide range of mainstream wireless technologies, such as, WLAN, Bluetooth, GSM, and UMTS. In addition, the course will explore security and privacy problems, and potential solutions of new and emerging wireless technologies, such as ZigBee, wireless mesh networks, and RFIDs.
