What is the role of a Cloud CASB in cybersecurity?

The role of a Cloud CASB (Cloud Access Security Broker) in cybersecurity is primarily focused on providing visibility and control over cloud applications. Organizations increasingly rely on cloud services for their operations, and while this brings many benefits, it also introduces new security risks. CASBs act as intermediaries between users and cloud service providers, allowing organizations to monitor user activity, enforce security policies, and manage data vulnerability.

By using a Cloud CASB, organizations can gain insights into how cloud apps are being used, which applications are being accessed, and if there are any policy violations. This visibility is crucial for ensuring compliance with regulations and organizational standards. Additionally, CASBs can help secure data in transit, identify and mitigate risks related to shadow IT (the use of unauthorized cloud applications), and perform threat detection.

The other options do not align accurately with the purpose of a Cloud CASB. For instance, aiming to eliminate the use of cloud applications contradicts the general trend of adoption of cloud services. Managing on-premises data centers lies outside the purview of a CASB's main functions, as CASBs are primarily concerned with cloud environments rather than traditional, on-premises infrastructures. Lastly, a CASB's role extends beyond just encrypting data at rest,
