How the security of widely spread edge computing is ensured?

Edge computing is the process done close to edge devices of network. It optimizes cloud computing system by taking control of applications and data. It provides real-time local data analysis from the IoT devices. In IoT use cases, where edge devices would collect massive data and send it all to a data center or cloud for processing. Edge computing prioritize the data locally, so some of it is processed locally, reducing the traffic to the central repository/cloud.
