Cloud computing has revolutionized the way organizations store, process, and manage data by providing flexible, scalable, and on-demand computing resources over the internet. However, the widespread adoption of cloud technologies has also introduced significant network security and privacy concerns, which pose critical challenges for both service providers and consumers. This paper critically analyzes the key network security and privacy issues in cloud computing, examining the threats, vulnerabilities, and mitigation strategies employed to address these concerns. It highlights common security risks, such as data breaches, insecure interfaces, and unauthorized access, as well as privacy issues stemming from data ownership, user consent, and compliance with legal frameworks. The paper also explores the evolving regulatory landscape and its implications for cloud providers and users. Finally, we propose future directions for enhancing security and privacy in cloud computing, emphasizing the role of emerging technologies, such as blockchain, encryption, and artificial intelligence, in strengthening cloud security frameworks.
