Abstract

Internet of Thing (IoT) is a concept where an object can transfer data through a network without requiring human interaction. Complex IoT networks make it vulnerable to cyber attacks such as DDoS UDP Flood attacks, UDP Flood attacks can disrupt IoT devices. Therefore, this study proposes an attack detection method using a deep learning approach with the Recurrent Neural Network (RNN) method. This study uses Principle Component Analysis (PCA) to reduce the feature dimension, before learning using RNN. The purpose of this study is to test the combined performance of the PCA and RNN methods to detect DDoS UDP Flood attacks on IoT networks. The testing in this study used 10 datasets sourced from CICIOT2023 containing UDP Flood and Benign DDoS traffic data, and the testing was carried out using three epoch parameters (iterations), namely 10, 50, and 100. The test results using RNN epoch 100 were superior, showing satisfactory performance with an accuracy value of 98%, precision of 99%, recall of 99%, and f1-score of 99%. Based on the experimental results, it can be concluded that combining PCA and RNN is able to detect UDP Flooding attacks by showing high accuracy.

Abstract

IoT devices have played an important role in driving DDoS attacks, and are a threat to IoT networks. One of them is the ICMP Flood attack. To overcome attacks on IoT, one of them uses an Intrusion Detection System (IDS). However, on the other hand, IDS has challenges in handling the complexity of high-dimensional data. One of the suggested solutions to overcome the problem of data dimensions is the use of feature selection techniques. The Forward Selection feature selection technique is used to eliminate irrelevant features. This study compares the performance of the Random Forest and SVM algorithms. For experimental purposes, this study used the CICIoT2023 dataset, which represents IoT traffic. The use of Forward Selection obtained 11 selected features that will be used in the machine learning process using the Random Forest and SVM methods. Feature selection affects the computation time or processing time, because the fewer features used, the more the system's workload in carrying out the classification process. The test results show that the use of feature selection improves the performance of random forest with an accuracy of 100%. Meanwhile, the SVM model gets better accuracy by using feature selection with the highest accuracy of 99.4508% in the supplied test set test.

Abstract

The prevalence of cloud computing among organizations poses a significant problem in ensuring security. Specifically, distributed denial of services (DDoS) attacks targeting cloud computing networks can lead to financial losses for consumers of cloud computing services. This assault has the potential to render cloud services inaccessible. The detection system serves as a remedy to prevent more substantial losses. This research aims to enhance the efficacy of the system detection model by integrating feature selection with three machine learning algorithms: decision tree (DT), random forest (RF), and naïve Bayes (NB). Therefore, our study suggests combining two phases of feature selection into the DDoS attack detection procedure. The first phase uses the information gain (IG) feature selection technique approach, and the second phase uses the principal component analysis (PCA) feature extraction approach. The technique is referred to as two-step feature selection. The test findings indicate that the implementation of two-step feature selection can enhance the performance of the DT and RF detection models by around 9%.

Abstract

The Internet of Things (IoT) presents significant security challenges as the number of connected devices continues to grow. One critical approach in developing efficient attack detection systems is the selection of relevant features to reduce model complexity without compromising accuracy. This study evaluates the effectiveness of Autoencoders as a feature reduction method for IoT network intrusion detection systems. Three machine learning algorithms are employed for comparative analysis: K-Nearest Neighbors (KNN), Naive Bayes (NB), and Support Vector Machine (SVM). The dataset is evaluated both before and after feature reduction using an Autoencoder, with performance assessed based on accuracy, precision, recall, F1-score, training time, and the number of features. Experimental results demonstrate that the Autoencoder can reduce the number of features by up to 30% without significantly degrading performance. In fact, the NB and SVM models exhibit improvements in both accuracy and training efficiency. The KNN model shows a minimal performance decline, which remains within acceptable limits. Overall, the Autoencoder proves to be an effective method for feature reduction, maintaining or even enhancing detection efficiency and performance. These findings support the use of Autoencoders as an efficient feature selection technique in IoT-based attack detection systems.

Abstract

The acknowledgment of innovation is a significant element in the supportability of a data innovation. The motivation behind this study was to decide and break down understudy acknowledgment and interest in utilizing the Mendeley application. This study utilizes an estimation model, specifically Technology Acceptance Model 3, in which the estimation model was created by Venkatesh and Bala. The model has eight factors and eight theories. Models and theories were gotten from information handling through an internet based poll comprising of 100 respondents from Mendeley application clients among Jambi Bangsa Dinamika Bangsa University understudies. The information from the respondents' outcomes were handled utilizing the Structural Equation Model (SEM) helped by SmartPLS 3 Software. The outcomes got in this study were that the TAM 3 utilized had a positive and huge impact between every factor, so it was reasoned that the Mendeley application was acknowledged by University understudies. The elements of the Jambi Nation and understudies who are keen on utilizing the Mendeley application are impacted by two principle aspects of TAM, in particular the view of value that has a positive (0.728) and critical (0.000) impact and the impression of convenience has a positive (0.613) and huge (0.000) impact so the two factors are extremely demonstrated to give positive and huge impact on interest in utilizing Mendeley.

Abstract

The rapid growth of the smartphone industry has increased market complexity, making objective segmentation more challenging. The objective of this study is to conduct a comparative evaluation of the K - Means and K - Medoids methods in grouping smartphone sales data based on multiple attributes, namely memory, storage, rating, selling price, and original price. Unlike prior studies, this research conducts a direct comparison using the same dataset and multiple evaluation metrics. A systematic data mining approach is implemented through the CRISP-DM framework, covering the stages of data understanding, preprocessing, modeling, and evaluation. The dataset comprises 3,114 smartphone instances, which are grouped into three clusters (k = 3), with performance measured using the Silhouette Coefficient and Davies–Bouldin Index (DBI). Based on the evaluation metrics, K - Medoids exhibits superior cluster cohesion with a Silhouette score of 0.344, exceeding that of K - Means (0.313). Conversely, K - Means demonstrates slightly better separation, as shown by its lower Davies–Bouldin Index (1.061 versus 1.079). Even so, K - Medoids is generally preferred due to its resilience to outliers and its consistency in producing stable clustering outcomes. These findings provide insights to support data-driven decision-making in smartphone market segmentation.
