A Secure Approach for Multicloud Environment

Abstract The adoption of multi-cloud environments—where organizations leverage services from multiple cloud providers—has grown significantly due to the demand for increased flexibility, redundancy, and cost optimization. However, this paradigm introduces complex security challenges, including data privacy, access control, inter-cloud communication risks, and compliance management. This paper presents a secure approach for managing and protecting data and services in a multi-cloud architecture. The proposed framework integrates encryption, federated identity management, policy-based access control, and secure communication protocols to mitigate potential threats. It also emphasizes the role of automation and continuous monitoring to enforce consistent security policies across heterogeneous cloud platforms. Experimental analysis and threat modeling demonstrate that the proposed approach significantly enhances data confidentiality, integrity, and system resilience in multi-cloud deployments. This work contributes toward building more robust, scalable, and secure cloud strategies for enterprise and government applications. 1. Keywords: Multi-Cloud Security, 2. Cloud Computing, 3.
