A Survey on Security Issues and Secure Frameworks in Internet of Things (IoT)

Technology advancements blend to masses with diverse and heterogeneous environments. The Internet of Things (IoT) and Cloud Computing has broken through reachability and availability of services. The security, privacy requirements and challenges manifest with the heterogeneity and the wide range of application domains posing a major concern in adoption of IoT. The literature addresses these changing requirements individually. The paper presents a top-down survey starting with general security challenges in IoT moving to security and privacy challenges, and later exploring security frameworks of IoT. The millions of wide range of devices produce a huge amount of data. Identifying and authenticating these devices and allowing them to process their data locally improves the performance, reduces the bandwidth usage, increases the battery usage and reduces the security risk of attacks making the devices self reliant. The survey identifies the less explored research gaps to group them and address the concerns related to device management, user management, key management, trust management and data management. The surveyed secured frameworks in IoT address the multiple dimensions of security concerns and their aspects.
