With the advent of internet of things (IoT) and IoT multimedia services in real-time applications, including smart healthcare, smart home, and smart connected transportation, IoT multimedia systems have significantly enhanced the lifestyle. However, the increased number of connected heterogeneous IoT multimedia devices have resulted in several vulnerabilities and cyberattacks. The existing multimedia in IoT multimedia security solutions are insufficient for detecting such complex attacks and require a self-adaptive security mechanism that can monitor the changing environment and detect, mitigate, plan, and prevent future prospective attacks in real time. In this study, we conduct a study of several self-adaptive security approaches for IoT multimedia and analyze them based on critical, security metrics to determine their level of support and the achieved satisfaction for IoT multimedia services. The evaluation …
