Abstract:

As organizations increasingly adopt cloud computing, ensuring robust security measures has become paramount. This research presents a comprehensive case study on the implementation of Policy-Based Access Control (PBAC) and data encryption mechanisms to enhance cloud security. The study investigates the effectiveness of PBAC in restricting access to sensitive data based on user roles, demonstrating a significant reduction in unauthorized access attempts. Additionally, the research evaluates the use of Advanced Encryption Standard (AES256) for data at rest and Transport Layer Security (TLS) for data in transit, confirming the absence of data breaches during the evaluation period. Performance assessments indicate that while the integration of PBAC and encryption mechanisms introduces a minimal overhead—approximately a 7% increase in average response times—the system remains well within acceptable performance thresholds. Furthermore, the implementation of Azure Key Vault for encryption key management has proven effective, providing automated key rotation and stringent access control, ensuring that only authorized personnel have access to sensitive encryption keys. This study highlights the dual advantages of enhanced security and efficiency, underscoring the significance of continuous monitoring and auditing processes to ensure compliance and identify potential vulnerabilities. The findings reinforce the feasibility of utilizing PBAC and data encryption as integral components of a secure cloud infrastructure, advocating for a well-defined security framework in cloud environments. Through this case study, the research contributes to the growing body of knowledge on cloud security practices, offering insights into scalable and flexible implementations that align with organizational security objectives..
