A Survey on Security Models, Techniques, and Tools for the Internet of Things

The Internet of things (IoT) connects a large number of smart objects that are seamlessly integrated into the information network to provide integrated services in all fields of human activity. Since IoT is vulnerable to various attacks, security and privacy are the key issues for IoT applications. In the past few years, IoT has presented a strong focus of research and different approaches have been recently proposed to address security and privacy. This paper reviews the research progress of IoT by analyzing the security requirements and presenting the different approaches and mechanisms used in IoT to ensure privacy, data protection and security.
