Multidisciplinary International Journal of Research and Development (MIJRD), 2022
The Internet of Things has become a very important sector and has recognized to be a billiondollar commerce. It is a large group of sensors and devices connected through wire or wireless and continuously shares data providing several benefits. Still, at the same time, the connectivity and its nature make it a target of cyber-attacks. These devices need to be secured. This paper proposes an intelligent model for securing IoT devices from such attacks. The authors used Gated Recurrent Unit (GRU) and Deep Neural Network (DNN) classifier, which has been trained and evaluated under the CICMAL2017 dataset. The performance of this model is assessed under all the standard evaluation metrics. The attained accuracy of our model is 99.3 %, with a precision of 99.7 %. Finally, to demonstrate the suggested model's efficacy, we compare it to alternative models.

International journal of cryptography and information security, 2019
As smart gadgets become more common in our lives through the Internet of Things (IoT) there's a balance, between convenience and the potential cybersecurity risks involved. This research focuses on enhancing security measures by looking into intrusion detection systems (IDS) and ensuring data privacy. By analyzing the UNSW NB15 dataset we investigate machine learning models to identify weaknesses and evaluate their effectiveness, in detecting threats. The aim is to develop security frameworks that can seamlessly merge with platforms using machine learning techniques. This study seeks to strengthen cybersecurity protocols while giving importance to user privacy and data security. The findings obtained are intended to benefit cybersecurity professionals, researchers and the general public by emphasizing the necessity of security systems to safeguard the expanding network.
Machine Learning in IoT Security: Current Solutions and Future Challenges
IEEE Communications Surveys & Tutorials, 2020
The future Internet of Things (IoT) will have a deep economical, commercial and social impact on our lives. The participating nodes in IoT networks are usually resourceconstrained, which makes them luring targets for cyber attacks. In this regard, extensive efforts have been made to address the security and privacy issues in IoT networks primarily through traditional cryptographic approaches. However, the unique characteristics of IoT nodes render the existing solutions insufficient to encompass the entire security spectrum of the IoT networks. This is, at least in part, because of the resource constraints, heterogeneity, massive real-time data generated by the IoT devices, and the extensively dynamic behavior of the networks. Therefore, Machine Learning (ML) and Deep Learning (DL) techniques, which are able to provide embedded intelligence in the IoT devices and networks, are leveraged to cope with different security problems. In this paper, we systematically review the security requirements, attack vectors, and the current security solutions for the IoT networks. We then shed light on the gaps in these security solutions that call for ML and DL approaches. We also discuss in detail the existing ML and DL solutions for addressing different security problems in IoT networks. At last, based on the detailed investigation of the existing solutions in the literature, we discuss the future research directions for ML-and DL-based IoT security.

Security Framework for IoT End Nodes with Neural Networks
International Journal of Machine Learning and Computing
The premise of the Internet of Things (IoT) is to connect not only computers and mobile devices, but also interconnect smart buildings, homes, and cities, as well as electrical and water grids, automobiles, and airplanes just to mention some examples. IoT leads to the development of a wide range of advanced information services that are pervasive, cost-effective, and can be accessed from anywhere and at any time. In this paper we present a multilayer architecture to integrate devices to the IoT, making it available from everywhere at any time. However, with the introduction of IoT we will be experiencing grand challenges to secure and protect its advanced information services due to the significant increase of the attack surface, complexity, heterogeneity, and number of interconnected resources. In order to deal with such challenges, we introduce an IoT Framework to build trustworthy and secure IoT applications and services. The framework enables developers to consider security issues at all IoT layers and integrate security algorithms with the functions and services offered in each layer instead of considering security in an ad-hoc and after thought manner. We show the applicability of our methodology to secure and protect IoT end nodes providing them with the capabilities for self-monitoring and self-recovering after an external event has occurred. Index Terms-Internet of things, access control, threat detection, neural networks. I. INTRODUCTION Advances in mobile and pervasive computing, and the exponential growth in sensors, actuators and controllers have led to the development of the Internet of Things (IoT). IoT will be a key enabling technology to develop smart services that will revolutionize the way we do business, maintain our health, manage critical infrastructures, conduct education, and how we secure, protect, and entertain ourselves [1], [2]. IoT-based services and systems are usually comprised of complex systems (e.g., Cyber Physical Systems, CPS) and characterized by interdependence, independence, cooperation, competition, distribution, and adaptation [3], [4]. In addition, IoT enables monitoring and controlling large number of heterogeneous devices and systems that are geographically dispersed by collecting, processing, and acting on the data generated by smart objects, systems or humans [5]. With the utilization of IoT devices and communication protocols, we are experiencing grand challenges to secure and protect such advanced services due Manuscript
Managing security in IoT by applying the deep neural network-based security framework
Eastern-European Journal of Enterprise Technologies
Security issues and Internet of Things (IoT) risks in several areas are growing steadily with the increased usage of IoT. The systems have developed weaknesses in computer and memory constraints in most IoT operating systems. IoT devices typically cannot operate complicated defense measures because of their poor processing capabilities. A shortage of IoT ecosystems is the most critical impediment to developing a secured IoT device. In addition, security issues create several problems, such as data access control, attacks, vulnerabilities, and privacy protection issues. These security issues lead to affect the originality of the data that cause to affects the data analysis.

Towards SDN-Enabled, Intelligent Intrusion Detection System for Internet of Things (IoT)
IEEE Access, 2022
The Internet of Things (IoT) has established itself as a multibillion-dollar business in recent years. Despite its obvious advantages, the widespread nature of IoT renders it insecure and a potential target for cyber-attacks. Furthermore, these devices broad connectivity and dynamic heterogeneous nature can open up a new surface of attack for refined malware attacks. There is a critical need to protect the IoT environment from such attacks and malware. Therefore this research aims to propose an intelligent, SDN-enabled hybrid framework leveraging Cuda Long Short Term Memory Gated Recurrent Unit (cuLSTMGRU) for efficient threat detection in IoT environments. To properly assess the proposed system, a state-of-the-art IoT-based dataset and standard evaluation metrics were used. The proposed model achieved 99.23 % detection accuracy with a low false-positive rate. For further verification, we compare the proposed model results with two of our constructed models (i.e., cuBLSTM and cuGRUDNN) and current benchmark algorithms. The proposed model outclassed the other models regarding speed efficiency, detection accuracy, precision, and other standard evaluation metrics. Finally, the proposed work employed 10-fold cross-validation to ensure that the results were completely unbiased.
