Internet of Things Security Techniques: a Survey

With the rapid growth of Internet technologies, Internet of Things (IoT) devices have become widely required. A huge number of smart devices around the world containing sensors and actuators are collecting data and processing it to perform specific actions. As these services deployed via the Internet, it becomes an easy target to the vulnerabilities. The defenses against these threats need to maximize and ensure high security to maintain the confidentiality, availability, and integrity of IoT resources. Different techniques and approaches have been proposed and established to protect smart devices and data from attacks. This survey uses the five layers architecture to explore different types of threats and vulnerabilities at an individual layer of IoT architecture. It also reviews different types of techniques and, approaches and methods to secure IoT architecture.
