A Survey on the Optimization of Security Components Placement in Internet of Things

The Internet of Things (IoT) environment has become the basic channel for the propagation of Distributed Denial of Service (DDoS) and malware intrusions. Cyber threats in IoT require new mechanisms and strategies to secure devices during their life cycle. These threats are real for operators and manufacturers of connected objects. Less and uncorrected secure devices are priority objectives for botnet operators to capture and obtain testing devices. In this article, we reviewed the problem of optimizing the placement of security components in IoT. We provide a generic view of the placement of security components at different levels in the IoT. First, we present an overview of IoT. Then, we conduct a demonstration and a thematic classification of numerous solutions for the placement of security components in the IoT. Thus, this presentation will be followed by a discussion of diverse research questions and a set of proposals for various future orientations of this domain to advance the problem resolution in this research article.
