Whole Life Cycle

Considering the importance of energy in our lives and its impact on other critical infrastructures, this paper starts from the whole life cycle of big data and divides the security and privacy risk factors of energy big data into five stages: data collection, data transmission, data storage, data use, and data destruction. Integrating into the consideration of cloud environment, this paper fully analyzes the risk factors of each stage and establishes a risk assessment index system for the security and privacy of energy big data. According to the different degrees of risk impact, AHP method is used to give indexes weights, genetic algorithm is used to optimize the initial weights and thresholds of BP neural network, and then the optimized weights and thresholds are given to BP neural network, and the evaluation samples in the database are used to train it. Then, the trained model is used to evaluate a case to verify the applicability of the model.

This chapter proposes an efficient centralized secure architecture for end to end integration of IoT based healthcare system deployed in Cloud environment. The proposed platform uses Fog Computing environment to run the framework. In this chapter, health data is collected from sensors and collected sensor data are securely sent to the near edge devices. Finally, devices transfer the data to the cloud for seamless access by healthcare professionals. Security and privacy for patients' medical data are crucial for the acceptance and ubiquitous use of IoT in healthcare. The main focus of this work is to secure Authentication and Authorization of all the devices, Identifying and Tracking the devices deployed in the system, Locating and tracking of mobile devices, new things deployment and connection to existing system, Communication among the devices and data transfer between remote healthcare systems. The proposed system uses asynchronous communication between the applications and data servers deployed in the cloud environment.

Security And Reliability

Cloud computing is touted as the next big thing in the Information Technology (IT) industry, which is going to impact the businesses of any size. Yet, the security issue continues to pose a big threat. Lack of transparency in the infrastructure and platforms causes distrust among users, and the users are reluctant to store information on the cloud. This undermines the potential of cloud computing and has proved to be a big barrier in the realization of the potential of cloud computing and its widespread adoption. The big paradigm shifts in the technology has not been reflected on the methods used to secure the technology. When an organization builds the infrastructure for cloud computing, security and privacy controls should be kept in mind from the holistic security perspective. It is also critical that the organization monitor and adapt controls to determine the success of cloud computing in dealing with the security and reliability issues relating to the cloud. From an organizational control perspective, the authors suggest an independent governing body to mediate between the cloud provider and the user, with the control framework that they have developed to fulfill their responsibilities of protecting the cloud environment.
