The Internet of Things (IoT) is a group of millions of devices having sensors and actuators linked over wired or wireless channels for data transmission. IoT has grown rapidly over the past decade with more than 25 billion devices are expected to be connected by 2020. The volume of data released from these devices will increase many-fold in the years to come. In addition to an increased volume, the IoT devices produces a large amount of data with a number of different modalities having varying data quality defined by its speed in terms of time and position dependency. In such an environment, machine learning algorithms can play an important role in ensuring security and authorization based on biotechnology, anomalous detection to improve the usability and security of IoT systems. On the other hand, attackers often view learning algorithms to exploit the vulnerabilities in smart IoT-based systems. Motivated from these, in this paper, we propose an innovative approach for spam detection in IoT devices using machine learning. Our technique harnesses the power of advanced machine learning algorithms to accurately identify and mitigate spam attacks, ensuring the integrity and security of IoT ecosystems. We present a comprehensive methodology that combines data collection, feature extraction, model training, and evaluation to build a robust spam detection system.

Introduction

I. INTRODUCTION

The Internet of Things (IoT) has revolutionized the way we interact with our surroundings, enabling seamless connectivity and communication among devices. However, the widespread adoption of IoT devices has brought significant challenges, particularly in terms of security and privacy. As these devices become increasingly interconnected, they become susceptible to various malicious activities, including spam attacks.

Spam attacks on IoT devices pose a severe threat to both individual users and the larger IoT ecosystem. They can result in unauthorized access, data leakage, and unauthorized control of devices, compromising user privacy and system integrity. Traditional spam detection techniques used in email or web-based environments are inadequate for IoT devices due to their unique characteristics and resource limitations.

To address this issue, our research focuses on developing an efficient spam detection technique specifically tailored for IoT devices. We leverage the power of machine learning algorithms to train models that can accurately identify and classify spam messages or activities on IoT devices. By utilizing machine learning, we can leverage the vast amounts of data generated by IoT devices and extract meaningful features to distinguish between legitimate and spam content.

The proposed technique encompasses several stages. Firstly, we collect a representative dataset of IoT device traffic, including both legitimate and spam-related data. Next, we employ feature extraction methods to transform the collected data into informative representations that capture the distinguishing characteristics of spam attacks. These features may include packet characteristics, communication patterns, payload analysis, or device behavior.

Subsequently, we utilize machine learning algorithms such as decision trees, support vector machines (SVM), or deep neural networks (DNN) to train our models on the extracted features. The models learn to differentiate between legitimate and spam activities based on patterns and trends observed in the data. We evaluate the performance of the trained models using appropriate metrics, such as accuracy, precision, recall, and F1-score, to ensure their effectiveness in spam detection.

The contributions of this research include a novel approach for spam detection in IoT devices, addressing the unique challenges and limitations of the IoT environment. By deploying an efficient and accurate spam detection system, we aim to enhance the security and privacy of IoT devices, safeguard user data, and prevent unauthorized access or control.
