Cloud computing has become the core foundation for data storage and sharing; however, still, security and privacy are huge problems it still encounters. This paper proposes a robust cloud security framework by integrating role-based access control (RBAC), two-step verification with biometric authentication, and third-party auditing (TPA) to achieve improved security over sensitive information. The proposed model provides access rights based on roles assigned to the users which will enhance the control over data as well as restrict unauthorized entry into it. The added layers of protection make two-factor verification, including biometric credentials, greatly safer. Third-party auditors constantly check up on and verify integrity in the data and policies aligned with access strategies. The experimental results demonstrate an ability of this framework to withstand data breaches and unapproved accesses and therefore further enhance cloud security. Such work will provide security through the development of a multi-layered mechanism ensuring the confidentiality, integrity, and accountability of the data.
