What is a primary function of a CASB regarding cloud data management?

A primary function of a Cloud Access Security Broker (CASB) is to prevent unauthorized access to cloud services and data. CASBs act as an intermediary between users and cloud service providers, enabling organizations to enforce their security policies and ensure compliance with regulations. They provide visibility into cloud application usage and can implement access controls that prevent unauthorized users or devices from accessing sensitive cloud-stored information.

This capability is crucial in today’s environment, where organizational data is often stored in multiple cloud services and can be at risk of exposure or unauthorized access. Through features such as identity verification, user behavior analytics, and automated policy enforcement, CASBs help protect against threats and data breaches, ensuring that only authorized individuals have access to critical resources.

In contrast, options related to network performance monitoring, managing local data storage, or configuring network routers do not align with the core focus of a CASB, which is centered around security and access control in cloud environments.
