9IoT Security Issues and Its Defensive Methods

The Internet of Things, which is abbreviated as IoT, refers to the network of physical objects that are connected or embedded with sensors and software to perform the desired task by connecting and interchanging data over the Internet. In this scenario, every object is provided with a unique identifier and the ability to exchange data automatically, which is openly subjected to vulnerabilities if it is not secured properly, especially when connected to the Internet, providing a large attack surface. Moreover, numerous high-profile incidents were reported, where commonly used IoT devices were used for cyber-attacks, which have been a great concern and have drawn attention toward IoT security. IoT security is one of the crucial steps in developing and implementing IoT devices. It refers to the technology segment which is engrossed in safeguarding the networks and devices associated with the IoT. IoT security focuses on the methods that tend to establish a secured Internet connection and the network to which the devices or objects are connected. It engages with a wide range of technologies, such as the Application Program Interface, Public Key Infrastructure (PKI) and Authentication. It also focuses on the methodologies, such as Network Access Control (NAC), Segmentation, security gateways, patch management, regular software updates, team integration and consumer education. Moreover, IoT security methods provide an efficient solution ...
