Which of the following countermeasures is designed specifically for preventing data breaches in cloud operations?

The focus of this question is on countermeasures specifically tailored to prevent data breaches in cloud operations. Regular audits of cloud provider security serve as an effective countermeasure because they involve systematically examining the security controls and practices of the cloud provider. These audits help identify vulnerabilities, misconfigurations, and weaknesses in security that could potentially lead to data breaches. By conducting regular assessments, organizations can ensure that the cloud service provider maintains compliance with security standards and best practices, significantly reducing the risk of a data breach.

These audits also provide insights into how data is handled, stored, and protected in the cloud environment. Continuous monitoring and evaluation can swiftly address any issues before they escalate into more significant security incidents, thereby playing a critical role in preventing data breaches.

In contrast, while detailed SLAs, user access reviews, and customizable security policies are essential components of a comprehensive cloud security strategy, they do not directly prevent data breaches on their own. SLAs outline expectations and responsibilities but do not guarantee data protection. User access reviews can help manage who has access to data, and customizable security policies can enhance security protocols, but neither addresses the underlying security controls of the cloud provider as effectively as regular audits do.
