Suricata vs snort3/11/2023 Existing works create clusters for known classes and manually label instances outside the clusters for detecting novel attack classes and concept drift, yet several challenges are present. We study the problem of active intrusion detection over network traffic streams. The feature selection methods more prefer channel-based features for the detection at post-attack and communication & control stages whereas host-based features are more influential for identifying the attacks originating from the bots. Some wrapper methods guarantee an optimal feature set regardless of the problem formulation but filter methods do not achieve that in all cases. The experimental results show that it is possible to achieve very high detection rates with very limited number of features. More specifically, we apply filter and wrapper methods with some machine learning methods and derived the optimal feature sets for each classification problem. In this paper, we focus on the minimization of feature sets for machine learning tasks that are formulated as six different binary and multi-class classification problems based on the stages of the botnet life-cycle. In various studies, it is demonstrated that machine learning can be utilized for the detection of IoT botnet attacks. The attackers compromise insecure IoT devices to enlarge their botnets for the purpose of launching more influential attacks against their victims. Experimental results show that BoostedEnsML outperformed existing ensemble models in terms of accuracy, precision, recall, F-score, and area under the curve (AUC), reaching 100% in each case on the selected datasets for multiclass classification. Based on the best two models, we construct our proposed BoostedEnsML model using LightGBM and XGBoost, as the combination of the two classifiers gives a lightweight yet efficient model, which is part of the target of this research. To ensure that we obtained a holistic and efficient model, we performed data balancing with synthetic minority oversampling technique (SMOTE) and adaptive synthetic (ADASYN) techniques after that, we used stratified K-fold to split the data into Two different datasets containing high-profile attacks, including distributed denial of service (DDoS), denial of service (DoS), botnets, infiltration, web attacks, heartbleed, portscan, and botnets, were used to train, evaluate, and test the IDS model. First, we train six different ML classifiers (DT, RF, ET, LGBM, AD, and XGB) and obtain an ensemble using the stacking method and another with a majority voting approach. This paper proposes an efficient method for detecting cyberattacks and network intrusions based on boosted ML classifiers. The boosting method is one of the approaches used to design an ensemble classifier. Many ensemble methods have been used with different ML classifiers, including decision trees and random forests, to propose IDS models for IoT environments. However, the dynamics of operation of intruders in IoT networks require more improved IDS models capable of detecting multiple attacks with a higher detection rate and lower computational resource requirement, which is one of the challenges of IoT systems. Machine learning (ML) algorithms have demonstrated high capacity in helping to mitigate attacks on IoT devices and other edge systems with reasonable accuracy. Considering the vast application areas of IoT systems, ensuring that cyberattacks are holistically detected to avoid harm is paramount. Of Things (IoT) systems, many security threats are currently ravaging IoT systems, causing harm to information. Our methodology should be useful for comparing other intrusion-detection products.įollowing the recent advances in wireless communication leading to increased Internet We observed no significant speed or accuracy advantage of Suricata over Snort in its current state, but it is still being developed. We conclude that Suricata can handle larger volumes of traffic than Snort with similar accuracy, and that its performance scaled roughly linearly with the number of processors up to 48. We used the same set of rules for both products with a few small exceptions where capabilities were missing. We did this and evaluated the speed, memory requirements, and accuracy of the detection engines in three kinds of experiments: (1) on the full traffic of our school as observed on its " backbone" in real time, (2) on a supercomputer with packets recorded from the backbone, and (3) in response to malicious packets sent by a red-teaming product. Previous work comparing the two products has not used a real-world setting. Suricata includes multi-threading to improve processing speed beyond Snort. The Suricata intrusion-detection system for computer-network monitoring has been advanced as an open-source improvement on the popular Snort system that has been available for over a decade.
