How is a cloud access security broker (CASB) configured when using a forward proxy?

A cloud access security broker (CASB) configured using a forward proxy involves placing a security appliance at the client network edge. This architecture allows the CASB to monitor and secure traffic between users within the organization and cloud service providers. By positioning the CASB as a forward proxy, it can effectively intercept and analyze all outgoing and incoming cloud traffic, ensuring that security policies are enforced consistently.

This setup allows for detailed visibility into user actions, the ability to enforce compliance policies, and the capability to prevent data breaches by applying security controls to cloud services. The forward proxy ensures that all user requests to cloud applications are routed through the CASB, enabling it to perform its functions, such as data loss prevention, threat protection, and access control.

In contrast, other configurations may not provide the same level of control over user traffic to cloud services. For example, installing agents or altering system settings (as indicated in other options) may limit visibility to certain devices or applications rather than encompassing all user interactions with the cloud. Similarly, an API-based CASB or a proxy positioned at the cloud network edge may not directly intercept user traffic in the same manner as a forward proxy deployed at the client network edge. This method is vital for organizations needing centralized control over cloud
