Network Security and Internet of Things

Abstract

Information security is the most critical component of the information system. It is also a challenge of the organizations to build a secure network. Every organization that developed its organizational network has faced security attacks, security risks, and vulnerabilities. Internet of things (IoT) is based on smart devices that connect with each other to formulate a complex network. Therefore, in order to build a secure traditional network and IoT network, understanding the basics of the network layers, network security, and different types of network attacks is essential for network security beginners who are interested in working in the field of information security. In this chapter, the authors reviewed the essential and most important concepts of information security, IoT, and explained these topics in an easy-to-understand way. Furthermore, the chapter discussed the basic level of information security challenges to familiarize the undergraduates and postgraduate students and IoT information security practitioners about it.
