According to the web search results, a cloud access security broker (CASB) is a software solution that stands between the cloud service provider and the cloud service user to enforce security controls. One of the most important benefits of using a CASB when migrating to a cloud environment is enhanced data governance, as it helps to protect sensitive information from unauthorized access, sharing, or loss. A CASB can also provide data classification, encryption, data loss prevention (DLP), and other features that enable organizations to manage and secure their data in the cloud.

Explanation
A technical vulnerability assessment is a process of identifying and evaluating the weaknesses and risks associated with a specific system, component, or network. A technical vulnerability assessment can help to determine the potential impact and likelihood of a security breach, as well as the appropriate measures to prevent or mitigate it. A technical vulnerability assessment should be performed on a personnel information management server whenever there is an increase in the number of unauthorized access attempts to the server, as this indicates that the server may have been compromised or targeted by an attacker12. Therefore, option C is the correct answer.
