Modeling and Analysis of Integrated Proactive Defense Mechanisms for Internet-of-Things

Internet of Things (IoT) has received significant attention due to its enormous advantages. Advances in IoT technologies can be easily leveraged to maximize effective service provisions to users. However, due to the high heterogeneity and the constrained resources of composed entities, and its large-scale networks, we face the following challenges [1]: (i) distributed technologies for communications, data filtering, processing, and dissemination with an enormous amount of various forms of data (e.g. text, voice, haptics, image, video) in large-scale networks with heterogeneous entities (i.e. devices, humans); (ii) severely restricted resources in battery, computation, communication (e.g. bandwidth), and storage, causing significant challenges in resource allocation and data processing capabilities; (iii) highly adversarial environments, introducing compromised, deceptive entities and data, which may result in detrimental impacts on the capabilities of critical mission-related decision-making; and (iv) highly dynamic interactions between individual entities, data, and environmental factors (e.g. network topology or resource availability), where each factoris highly dynamicin time/space. Due to these characteristics of IoT environments, highly secure, lightweight defense mechanisms are in need to protect and defend a system (or network) against potential attacks.
