IoT Security Techniques and Security Threats: A Survey

New inventions in technology have made us digitally dependent as we obtain maximum benefit and comfort from it. Internet of Things (IoT) is a technology where the internet interacts with objects. IoT devices have been in continuous use and have become a fundamental part of our modern society. Usage of IoT in various fields includes home security, medical industry, military, agriculture, transportation, etc. Such devices enable our living spaces to be more autonomous, adaptive, efficient, and convenient. However, security and privacy are the biggest concerns while using these digitally equipped spaces. The dramatic increase in the number of IoT network-connected devices has increased the malware attacks. IoT security and privacy thus aim to protect the IoT devices and harden the IoT system architecture using firewalls, video surveillance, intrusion detection system, and other techniques. In accordance, many security techniques designed and developed create secure usage Iot at least to some extent. This paper presents some of the security techniques and solutions that have been in use to overcome IoT security issues. Also, the various security threats and security attacks are mentioned, along with the respective security solutions.
