The paper considers how cloud computing has both changed data management in organizations and increased new security concerns, with a focus on two core cloud security features: Role-Based Access Control and Third-Party Auditing Mechanisms. RBAC provides least privilege and makes access management easier due to the automatization of permissions through predefined roles. Independent audits, in particular, compliance assessment for data integrity, confirm whether providers adhere to certain standards. It gives insights into the implementation of RBAC, auditing significance, and how they synergize to effectively enhance cloud security. The paper offers practical, hands-on guidance on how to manage these mechanisms that engender trust in cloud-based services and ensure cloud security.
