A Machine Learning Approach for Intrusion Detection

Master's thesis in Information- and communication technology (IKT590)Securing networks and their confidentiality from intrusions is crucial, and for this rea-son, Intrusion Detection Systems have to be employed. The main goal of this thesis is to achieve a proper detection performance of a Network Intrusion Detection System (NIDS). In this thesis, we have examined the detection efficiency of machine learning algorithms such as Neural Network, Convolutional Neural Network, Random Forestand Long Short-Term Memory. We have constructed our models so that they can detect different types of attacks utilizing the CICIDS2017 dataset. We have worked on identifying 15 various attacks present in CICIDS2017, instead of merely identifying normal-abnormal traffic. We have also discussed the reason why to use precisely this dataset, and why should one classify by attack to enhance the detection. Previous works based on benchmark datasets such as NSL-KDD and KDD99 are discussed. Also, how to address and solve these issues. The thesis also shows how the results are effected using different machine learning algorithms. As the research will demon-strate, the Neural Network, Convulotional Neural Network, Random Forest and Long Short-Term Memory are evaluated by conducting cross validation; the average score across five folds of each model is at 92.30%, 87.73%, 94.42% and 87.94%, respectively. Nevertheless, the confusion metrics was also a crucial measurement to evaluate the models, as we shall see.

Analysis of Theoretical and Applied Machine Learning Models for Network Intrusion Detection

Network Intrusion Detection System (IDS) devices play a crucial role in the realm of network security. These systems generate alerts for security analysts by performing signature-based and anomaly-based detection on malicious network traffic. However, there are several challenges when configuring and fine-tuning these IDS devices for high accuracy and precision. Machine learning utilizes a variety of algorithms and unique dataset input to generate models for effective classification. These machine learning techniques can be applied to IDS devices to classify and filter anomalous network traffic. This combination of machine learning and network security provides improved automated network defense by developing highly-optimized IDS models that utilize unique algorithms for enhanced intrusion detection. Machine learning models can be trained using a combination of machine learning algorithms, network intrusion datasets, and optimization techniques. This study sought to identify which variation of these parameters yielded the best-performing network intrusion detection models, measured by their accuracy, precision, recall, and F1 score metrics. Additionally, this research aimed to validate theoretical models’ metrics by applying them in a real-world environment to see if they perform as expected. This research utilized a quantitative experimental study design to organize a two-phase approach to train and test a series of machine learning models for network intrusion detection by utilizing Python scripting, the scikit-learn library, and Zeek IDS software. The first phase involved optimizing and training 105 machine learning models by testing a combination of seven machine learning algorithms, five network intrusion datasets, and three optimization methods. These 105 models were then fed into the second phase, where the models were applied in a machine learning IDS pipeline to observe how the models performed in an implemented environment. The results of this study identify which algorithms, datasets, and optimization methods generate the best-performing models for network intrusion detection. This research also showcases the need to utilize various algorithms and datasets since no individual algorithm or dataset consistently achieved high metric scores independent of other training variables. Additionally, this research also indicates that optimization during model development is highly recommended; however, there may not be a need to test for multiple optimization methods since they did not typically impact the yielded models’ overall categorization of v success or failure. Lastly, this study’s results strongly indicate that theoretical machine learning models will most likely perform significantly worse when applied in an implemented IDS ML pipeline environment. This study can be utilized by other industry professionals and research academics in the fields of information security and machine learning to generate better highly-optimized models for their work environments or experimental research

Leveraging Machine Learning for Network Intrusion Detection in Social Internet Of Things (SIoT) Systems

This research investigates the application of machine learning models for network intrusion detection in the context of Social Internet of Things (SIoT) systems. We evaluate Convolutional Neural Network with Generative Adversarial Network (CNN+GAN), Generative Adversarial Network (GAN), and Logistic Regression models using the CIC IoT Dataset 2023. CNN+GAN emerges as a promising approach, exhibiting superior performance in accurately identifying diverse intrusion types. Our study emphasizes the significance of advanced machine learning techniques in enhancing SIoT security by effectively detecting anomalous behaviours within socially interconnected environments. The findings provide practical insights for selecting suitable intrusion detection methods and highlight the need for ongoing research to address evolving intrusion scenarios and vulnerabilities in SIoT ecosystems

A Supervised Machine Learning Based Intrusion Detection Model for Detecting Cyber-Attacks Against Computer System

Internet usage has become essential for correspondence in almost every calling in our digital age. To protect a network, an effective intrusion detection system (IDS) is vital. Intrusion Detection System is a software application to detect network intrusion using various machine learning algorithms. The function of the expert has been lessened by machine learning approaches since knowledge is taken directly from the data. The fact that it makes use of all the features of an information packet spinning in the network for intrusion detection is weakened by the employment of various methods for detecting intrusions, such as statistical models, safe system approaches, etc. Machine learning has become a fundamental innovation for cyber security. Two of the key types of attacks that plague businesses, as proposed in this paper, are Denial of Service (DOS) and Distributed Denial of Service (DDOS) attacks. One of the most disastrous attacks on the Internet of Things (IOT) is a denial of service.  Two diverse Machine Learning techniques are proposed in this research work, mainly Supervised learning. To achieve this goal, the paper represents a regression algorithm, which is usually used in data science and machine learning to forecast the future. An innovative approach to detecting is by using the Machine Learning algorithm by mining application-specific logs. Cyber security is a way of providing their customers the peace of mind they need knowing that they have secured their information and money
