Traditional Cloud services may be unable to meet the computational service needs of many kinds of Service Consumers, given the fluctuating demand for these services. Despite the emergence of Multi Clouds and Cross-Clouds, there exists a substantial demand for Fog and Edge systems to address the requirements of IoT. It is clear that the current necessity is an environment that presents all frameworks and options to both Consumers and Providers according to the demands and needs of the present task. This necessitates a harmonious amalgamation of Cloud with Fog and Edge environments capable of interfacing with IoT devices via IoT gateways situated in proximity to the devices. Contemporary progress in computing, storage, and networking demands the creation of innovative security frameworks to protect the Cloud environment amid its intricacies. The study suggests the implementation of a Security Manager to protect the Integrated ecosystem and facilitate uninterrupted operations. The suggested Security Manager emphasizes Identity and Access Management by executing Authentication and Authorization with Zero Trust principles. Given the dynamic nature of the environment, characterized by diverse Providers and Consumers, it is essential to protect resources and services from the ground up. The Security Manager executes Security Orchestration utilizing Micro segmentation alongside suitable algorithms
