ABSTRACT
Internet of things (IoT) is the next era of communication. Using IoT, physical objects can
be empowered to create, receive and exchange data in a seamless manner. Various IoT applications focus
on automating different tasks and are trying to empower the inanimate physical objects to act without any
human intervention. The existing and upcoming IoT applications are highly promising to increase the level
of comfort, efficiency, and automation for the users. To be able to implement such a world in an ever
growing fashion requires high security, privacy, authentication, and recovery from attacks. In this regard, it
is imperative to make the required changes in the architecture of IoT applications for achieving end-to-end
secure IoT environments. In this paper, a detailed review of the security-related challenges and sources of
threat in IoT applications is presented. After discussing the security issues, various emerging and existing
technologies focused on achieving a high degree of trust in IoT applications are discussed. Four different
technologies: Blockchain, fog computing, edge computing, and machine learning to increase the level of
security in IoT are discussed.
