A Comprehensive Study of IoT Application Layer Security Management

IoT is a revolution of a new era. In all of this applications data transfer from machine to machine, machine to human. Between this transection of data should ensure security. This technology makes human life easy but security is the main challenge. Compromising of security is the great threat of human life. Security is widely interconnected to the Internet of Things technology. Lots of researchers search for solutions to these threats and provide lots of techniques to provide security. All of these techniques should need a proper arrangement. The application layer is the last layer and the only one that directly interacts with the end-user. To be secured all the user and service providers should aware of these threats and security issues. In this layer, the user uses and get services from the service provider. To give proper security different approaches have been taken to give security to have secured services. The paper helps future researchers to have a comparative analysis of the application layer protocol's performance. Furthermore, the paper discusses the architecture implementations, security provisions of certain recognized application layer protocols nowadays being used in an IoT technology also discusses about traditional solutions.
