A Novel User Authentication and Access Control Model in Enhancing Cloud Security

The ever-increasing use of cloud computing has made data and resource security a major issue. Unauthorized access to data and cloud services puts many people and organizations in danger. This paper aims to improve cloud security by addressing this difficulty by presenting a novel approach for user authentication and access control. The suggested architecture offers a complete solution for avoiding unwanted access in cloud environments by combining cutting-edge user authentication techniques with strong access control mechanisms. The goal of the research is to create a framework that is user-centric and gives security and user experience equal priority. It makes use of cutting-edge techniques and technologies, including Secure Socket Layer (SSL), Encryption, Adaptive Authentication, and Multi-Factor Authentication (MFA), to guarantee quick and easy user authentication and, ultimately, that only authorized users can access cloud services. Through a rigorous evaluation and testing procedure, this technique shows how effective it is in avoiding disruptions to user convenience while preventing unlawful access.
