Abstract
Cloud computing offers scalable and adaptable computing resources, it has completely changed how businesses run. However, security issues have become crucial due to the enormous volumes of data being processed and stored in the cloud. In this paper presents a review of security techniques employed in cloud computing environments. It discusses various aspects including data encryption, access restriction mechanisms, recognize and authentication management, network security measures, and compliance frameworks. Additionally, the study explores emerging technologies like homomorphic encryption and blockchain for enhancing security in the cloud. The analysis emphasizes how crucial a multi-layered security approach is to reducing the risks of insider threats, illegal access, and data breaches. The reviewed studies propose various methods for enhancing cloud security, data encryption, and intrusion detection, showing promising results such as high accuracy and robustness in controlled experiments. However, most approaches face limitations in real-time applicability, adaptability to diverse attack scenarios, or scalability across platforms. While techniques like hybrid encryption, SMOTE-based IDS, and ML-based SSE demonstrate effectiveness, they often struggle with practical deployment challenges such as overhead, unpredictability, or incomplete protection.
