IoT cihazlarda veri akışının analizi ve akıllı ev ağındaki MUD uygulamalarının güvenliğinin değerlendirilmesi

IoT usage has shown significant growth in the past decades. A major target for the IoT market is the living spaces which have become smarter by the integration of IoT devices. However, the network infrastructure have not been developed from the perspective of Cyber security. IoT devices are subject to Cyber security threats in multiple fronts. For example, infected IoT devices may contribute to DDoS attacks that target global Internet services, such as the DNS. For mitigation of the attacks, various solutions have been proposed. In this thesis, we review available solutions with a particular focus on the application of a standardized whitelisting method, namely Manufacturer User Description (MUD). For an evaluation of MUD usage in IoT networks, we analyzed traffic of two devices with the aim of detecting recognizable and distinctive traffic patterns. We established specific MUD files based on the detected traffic patterns and evaluated the MUD files for the validation of their proof of work.
