Impact of Feature Selection Methods on Machine Learning-based for Detecting DDoS Attacks : Literature Review

Abstract

Cybersecurity attacks are becoming increasingly sophisticated and increasing with the development of technology so that they present threats to both the private and public sectors, especially Denial of Service (DoS) attacks and their variants which are often known as Distributed Denial of Service (DDoS). One way to minimize this attack is by using traditional mitigation solutions such as human-assisted network traffic analysis techniques but experiencing some limitations and performance problems. To overcome these limitations, Machine Learning (ML) has become one of the main techniques to enrich, complement and enhance the traditional security experience. The way ML works are based on the process of data collection, training and output. ML is influenced by several factors, one of which is feature engineering. In this study, we focus on the literature review of several recent studies which show that the feature selection process greatly impacts the level of accuracy of this ML. Datasets such as KDD, UNSW-NB15 and others also affect the level of accuracy of ML. Based on this literature review, this study can observe several feature engineering strategies with relevant impacts that can be chosen to improve ML solutions on DDoS attacks.

An Adaptive DDoS Detection and Classification Method in Blockchain Using an Integrated Multi-Models

“…With their complex and ever-evolving nature, Blockchain networks often stump traditional detection techniques. However, with machine learning's adeptness at using historical data to differentiate between regular and anomalous traffic patterns, the timely identification of DDoS assaults becomes feasible [12,13]. This adaptability ensures that the system remains consistent in its performance, even when faced with the evolving tactics of attackers.ng techniques employed by attackers, hence ensuring consistent and effective detection performance.…”

“…Different datasets such as KDD, UNSW-NB15, and others can affect the accuracy of ML. Several feature engineering strategies can be chosen to improve ML solutions on DDoS attacks (Faiz et al, 2022).…”
