What is the primary function of a cloud access security broker (CASB)?

• A. To store data securely in the cloud
• B. To enforce security policies for access to cloud services
• C. To perform regular system updates
• D. To handle user authentication alone

Answer: (B)

The primary function of a cloud access security broker (CASB) is to enforce security policies for access to cloud services. CASBs serve as an intermediary between users and cloud service providers, allowing organizations to ensure that their security policies are applied consistently across different cloud applications. This helps in managing risks associated with data breaches and unauthorized access by providing visibility into cloud services, ensuring compliance with regulations, and enabling secure data sharing. By monitoring user activity, data transactions, and compliance requirements, a CASB can identify threats and implement security controls that protect sensitive data. This capability is crucial as organizations increasingly adopt cloud-based services, making it essential to secure those environments against various threats. The other options focus on different functionalities that are not the primary purpose of a CASB. While secure storage, system updates, and user authentication are important aspects of cloud security, they do not capture the core role of a CASB, which revolves specifically around the enforcement of security policies in cloud environments.
