Intrusion detection in IoT and wireless networks using image-based neural network classification



Telecommunication networks play more and more important role in our modern times, and there are significant security risks associated with both wireless and wired networks. These risks stem from various malicious actions and security threats that have emerged with the development of Fourth Generation (4G), Fifth Generation (5G), and Internet of Things (IoT) networks. Machine learning (ML) algorithms have been applied to Intrusion Detection Systems (IDSs) due to their capacity to their ability to detect complex network traffic patterns. Deep learning (DL) networks are highly effective in processing images and videos and they have potential to solve other types of data.
 
Given the characteristics of network traffic records used for intrusion detection in wireless and wired networks, we propose a simple data preprocessing method to convert the data into a grid-structured format, making it compatible with image processing networks. To validate the proposed structure, modified LeNet networks have been used for intrusion detection based on the NSL-KDD and CICIoV2024 (Canadian Institute for Cybersecurity Internet of Vehicles 2024 dataset) benchmark datasets. The simulation results indicate that methods based on extracted features may not always guarantee improved performance.
 
The proposed Image Classification Neural Network-based Intrusion Detection (ICNN-ID) outperforms the compared existing methods. The multiclass classification experimental results show that the proposed LeNet-based IDS achieved a test accuracy (TAC) of 89.97% for NSL-KDD and nearly 100% (99.996%) for CICIoV2024. Additionally, it offers higher accuracy and improved robustness compared to a one-dimensional CNN and a recent deep learning model that integrates deep convolutional neural networks (DCNN) and bidirectional long short-term memory (BiLSTM).

The miniaturization of chips has promoted the rapid development of networks, including mobile networks, wireless networks and wired networks including computer networks. The network has greatly facilitated the acquisition of personal information and industrial upgrading. However, this advantage comes with increased vulnerability to various cyber threats. Intrusion Detection Systems (IDS) have become essential for safeguarding wireless networks by identifying and mitigating unauthorized access and malicious activities. Traditional IDS approaches often rely on signature-based detection methods, which, although effective against known threats, struggle with novel and evolving attacks. Artificial Intelligence (AI) refers to the simulation of human intelligence in machines, enabling them to perform tasks such as learning, reasoning, and problem-solving.

Global Lighthouse Network

Smart, sustainable manufacturing: 3 lessons from the Global Lighthouse Network Launched in 2018, when more than 70% of factories struggled to scale digital transformation beyond isolated pilots, the Global Lighthouse Network set out to identify the world’s most advanced production sites and create a shared learning journey to up-level the global manufacturing community. In the past seven years, the network has grown from 16 to 201 industrial sites in more than 30 countries and 35 sectors, including the latest cohort of 13 new sites. This growing community of organizations is setting new standards for operational excellence, leveraging advanced technologies to drive growth, productivity, resilience and environmental sustainability. But what exactly is a Global Lighthouse and what has the network achieved? What is the Global Lighthouse Network? The Global Lighthouse Network is a community of operational facilities and value chains that harness digital technologies at scale to ac...

Multi-Modal Data

Multi-Task Federated Split Learning Across Multi-Modal Data with Privacy Preservation With the advancement of federated learning (FL), there is a growing demand for schemes that support multi-task learning on multi-modal data while ensuring robust privacy protection, especially in applications like intelligent connected vehicles. Traditional FL schemes often struggle with the complexities introduced by multi-modal data and diverse task requirements, such as increased communication overhead and computational burdens. In this paper, we propose a novel privacy-preserving scheme for multi-task federated split learning across multi-modal data (MTFSLaMM). Our approach leverages the principles of split learning to partition models between clients and servers, employing a modular design that reduces computational demands on resource-constrained clients. To ensure data privacy, we integrate differential privacy to protect intermediate data and employ homomorphic encryption to safeguard client m...
