Abstract With the advancing trends in the field of information technology, the data users were subjected to face differernt of attacks. Hence effective and prompt detection of malicious attacks must be optimized in terms of confidentiality, privacy, availability and integrity. Accordingly this research paper provides an effective mechanism for detecting and classifying DDoS attacks such as TCP-SYN, UDP flood, ICMP echo, HTTP flood, Slowloris Slow Post and Brute Force attack, by utilizing machine learning methods within SNMP-MIB dataset. MIB (Management Information Base) is meant for attack classification database linked to the SNMP (Simple Network Management protocol). Three classifiers are considered such as MLP, Random forest, Adaboost to construct the detection model. Significantly, Gated Recurrent Unit Neural Network based on Bidirectional Weighted Feature Averaging (GRU-BWFA) classifier is utilizing as a proposed classifier for high detection rate and accuracy in distinguishing the mentioned DDoS attacks. Feature selection is performed using the Enhanced Salp Swarm Optimization technique to select the optimal features for identify the attacks. The application of various classifier provides a detailed study on the effectiveness of SNMP-MIB dataset in detecting DDoS attacks. Empirical findings indicate that machine learning methods are highly effective at detecting and classifying the attacks with a higher accuracy rate.

With the great potential of internet of things (IoT) infrastructure in different domains, cyber-attacks are also rising commensurately. Distributed denials of service (DDoS) attacks are one of the cyber security threats. This paper will focus on DDoS attacks by adding the design of an intrusion detection system (IDS) tailored to IoT systems. Moreover, machine learning techniques will be investigated to distinguish the data representing flows of network traffic, which include both normal and DDoS traffic. In addition, these techniques will be used to help make a refined detection model for identifying different types of DDoS attacks. Furthermore, the performance of machine learning-based proposed solution is validated using N-BaIoT dataset and compared through different evaluation metrics. The experimental results show that the proposed IDS not only detects DDoS attacks types but also has a high detection rate and low false positive rate, which argues the usefulness of the proposed approach in comparison with several existing DDoS attacks detection techniques.
