A Comprehensive Study on Firewall for IoT Devices, Policies, and Security Issues

Abstract
As networked communications continue to expand and grow in complexity, the network has increasingly moved to include more forms of communication. The fourth industrial revolution is creating an environment in which everything will be interconnected and intelligent. Internet Of Things is the cornerstone of this new era. With the advent of the internet of things, privacy and security of sensitive data has become a major concern. As the tools used for an attack become more sophisticated with the use of Artificial Intelligence and Machine Learning. According to Threatpost, this year has seen a 100 percent surge in IoT infections observed over wireless networks. IoT devices are now responsible for 32.72 percent of all infections observed in mobile and Wi-Fi networks – up from 16.17 percent in 2019. The usage of IoT in different applications is expected to rise rapidly in the coming years. The IoT allows billions of devices, peoples, and services to connect with others and exchange information. Due to the increased usage of IoT devices, the IoT networks are prone to various security attacks. The deployment of efficient security and privacy protocols in IoT networks is extremely needed to ensure confidentiality, authentication, access control, and integrity, among others. In this paper, an extensive comprehensive study on security and privacy issues related to Firewall for IoT Devices. Keywords - Firewall; Firewalling; IoT; Network; Security; Policies
