The evolving nature of cloud computing changes data management and storage. Thus, there is a need to have an ensured safe way of managing data. Currently, most security frameworks have the problem of imposing significant computational overhead, thus reducing efficiency. This paper proposes a lightweight data security system designed especially for cloud environments. Advanced encryption techniques, streamlined key management processes, and real-time threat monitoring characterize this system for the safety of data while minimizing resource consumption. This approach addresses the unique challenges of scalability and performance in cloud computing by balancing robust protection with operational efficiency. The effectiveness of the proposed solution in securing sensitive data is demonstrated, making it a practical and efficient alternative to traditional security methods.
