Securing the IoT. Utilizing conformance tessuites for fuzzing

IoT devices are widely used in almost all vertical domains like homes, factories or as wearables on the body. This diversity is reflected in a variety of implementations which creates challenges for security testing due to the lag of applicability of out-of-the-box security testing solutions, like existing in other areas. We're introducing a security testing suite that is capable of providing security tests. Our security test suite is part of the Eclipse IoT-Testware project. It is capable of creating fuzz test cases from conformance test suites for devices automatically, regardless of the used protocols. Eclipse IoT-Testware reads into the communication between two devices, generates a model of the used protocol and generates fuzz data using the generation library Fuzzino. This solution has found vulnerabilities in ITS devices and flaws in devices using COAP and MQTT
