LRDDoS Attack Detection on SD-IoT Using Random Forest with Logistic Regression Coefficient

Software Defined Internet of Things (SD-IoT) is currently developed extensively. The architecture of the Software Defined Network (SDN) allows Internet of Things (IoT) networks to separate control and data delivery areas into different abstraction layers. However, Low-Rate Distributed Denial of Service (LRDDoS) attacks are a major problem in SD-IoT networks, because they can overwhelm centralized control systems or controllers. Therefore, a system is needed that can identify and detect these attacks comprehensively. In this paper, the authors built an LRDDoS detection system using the Random Forest (RF) algorithm as the classification method. The dataset used during the experiment was considered as a new dataset schema that had 21 features. The dataset was selected using feature importance - logistic regression with the aim of increasing the classification accuracy results as well as reducing the computational burden of the controller during the attack prediction process. The results of the RF classification with the LRDDoS packet delivery speed of 200 packets per second (pps) had the highest accuracy of 98.7%. The greater the delivery rates of the attack pattern, the accuracy results increased.
