Quantifying Risk in Cloud Security.pdf

Cloud computing has become an integral part of modern IT infrastructure, offering scalability, cost-efficiency, and accessibility. However, its adoption introduces various security risks, making it crucial for organizations to quantify these risks effectively. Risk quantification in cloud security involves assessing threats to confidentiality, integrity, and availability while implementing structured frameworks and metrics. This paper explores key security metrics such as access control violations, data encryption coverage, malware detection rates, and system uptime percentage. Furthermore, it examines established risk assessment frameworks, including the NIST Cybersecurity Framework, the Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM), ISO/IEC 27001, and the MITRE ATT&CK framework. By analyzing these models, organizations can enhance security risk assessment, ensure regulatory compliance, and improve their cybersecurity posture. The paper concludes with best practices for quantifying and mitigating cloud security risks through automation, regular audits, and security awareness programs.
