Cybersecurity in the Internet of Things (IoT) - Review

The quick growth of the IoT has brought more ease, greater efficiency, and automation to industries. Still, connected systems in IoT bring up many cybersecurity challenges since IoT settings have many resources and a large variety of devices. This study helps to identify the key security problems, possible weaknesses, and dangers of IoT systems. It reviews IoT infrastructure security approaches, like encryption, authentication, intrusion detection, and blockchain, and studies their pluses and minuses. Important topics discussed in the paper are the scarcity of common security standards and the problem of securing devices and networks that work on the edges (peripheries) of the network. The article puts forward an approach to security that combines several defensive strategies, intelligent detection of threats, and tailored policies for different stakeholders to deal with these issues. It is emphasized that the security of IoT depends on the ability to change and work with different systems. With this assessment, the conversation about IoT cybersecurity is broadened by looking at the present state, noticing new trends, and helping set up future studies.
