A Comprehensive Review of Cloud Security and Trust Management: Challenges, Threats, Security Techniques, and Future Directions

Abstract: Cloud computing has become one of the most widely used technologies for delivering computing resources and services over the internet. It provides several benefits such as flexibility, scalability, cost-effectiveness and easy access applications and data. However rapid growth of cloud services has also increased security concerns. Since sensitive and confidential information is stored over cloud platforms that are highly vulnerable to cyber-attacks, data breaches, malware attacks and insider threats. This paper presents an overview of cloud computing and its service models, along with major security threats and challenges, and also presents security solutions in the cloud environment. Various security techniques, such as encryption, authentication, access control, Artificial Intelligence-based security, and blockchain-based security, are discussed.
