Cloud Security in Middleware Architecture

The new Internet of Things (IoT) has increased the need for computing, connectivity, and storage capacities as the amount of sensitive data grows. Since it provides on-demand access to a common pool of resources such as processors, storage, software, and services, cloud computing can seem to be a convenient solution. However, there is a cost, as excessive communications burden not only the core network, but also the cloud data centre. As a result, it’s critical to consider appropriate approaches and security middleware solutions. In this chapter, we define a middleware architecture to address security concerns and explore the general concept of cloud to achieve a higher level of security. Since it is designed to pre-process data at the network’s edge, this security middleware functions as a smart gateway. Data can be processed and stored locally on fog or sent to the cloud for further processing, depending on the information obtained. Furthermore, the devices communicate via middleware, which gives them access to more computing power and improved security capabilities, allowing them to conduct safe communications. We discuss these concepts in detail, and explain how this is effective to cope with some of the most relevant security challenges.
