ISC2 CISSP Practice Question

A Cloud Access Security Broker (CASB) is specifically designed to provide visibility into cloud service usage, enforce security policies across multiple platforms, and prevent unauthorized data transfers. CASBs act as intermediaries between users and cloud service providers, enabling organizations to monitor and control data flow to and from cloud applications.

Security Information and Event Management (SIEM) systems focus on real-time analysis of security alerts but do not specifically provide visibility or control over cloud service usage. Data Loss Prevention (DLP) helps prevent unauthorized data transfers but lacks the comprehensive visibility and policy enforcement across multiple cloud platforms that CASB offers. DLP may also impact appropriate and necessary data transfers. Digital Rights Management (DRM) is primarily concerned with protecting digital content from unauthorized access and distribution, which is not directly related to managing cloud service usage or enforcing security policies across platforms.
