The Internet of Things (IoT) has transformed not only the way we communicate and operate our devices, but it has also brought us significant security challenges. A typical IoT network architecture consists of four levels: a device, a network, an application, and a service, each with its own security considerations. There are three types of IoT networks: Personal Area Networks (PANs), Local Area Networks (LANs), and Wide Area Networks (WANs). Each type has its own security requirements, so it is important to understand their particular security requirements. Several communication protocols that are used in IoT networks, like Wi-Fi and Bluetooth, are also susceptible to vulnerabilities that require the implementation of additional security measures. In addition to physical security challenges, there are numerous security challenges in the form of authentication, encryption, software vulnerabilities, DoS attacks, data privacy, and supply chain security. In order to deal with these challenges, we need to take a multi-layered approach that is comprised of physical, technical, and organizational measures. In this paper, we present an overview of IoT network architecture, along with an analysis of security challenges.
