Exam SY0-601 topic 1 question 125 discussion

A cloud access security broker (CASB) is on-premises or cloud-based software that sits between a cloud service consumer and a cloud service provider. It serves as a tool for enforcing an organization's security policies through risk identification and regulation compliance whenever its cloud-residing data is accessed.

By process of elimination A seems to be the correct answer

When in doubt, its CASB

A. CASB

A Cloud Access Security Broker (CASB) is the best security solution to reduce the risk of shadow IT related to unsanctioned high-risk SaaS applications. CASB provides visibility and control over the use of cloud services within an organization, helping to detect and block unauthorized cloud applications. It acts as an intermediary between users and cloud services, allowing organizations to enforce security policies, monitor cloud activity, and prevent access to unsanctioned or high-risk cloud applications. By implementing a CASB solution, the Chief Information Security Officer (CISO) can gain better visibility into the usage of cloud services, enforce security policies, and block access to unauthorized or high-risk applications, effectively reducing the risk of shadow IT and enhancing overall cloud security.

CASB is a security solution that provides organizations with visibility into and control over cloud-based services and applications accessed by their users. It acts as an intermediary between users and cloud service providers, allowing security teams to enforce security policies and monitor cloud usage. By implementing a CASB, the organization can gain insights into all cloud applications being used by its employees, including unsanctioned ones, and apply policy-based controls to block access to high-risk SaaS applications. This helps mitigate the risks associated with shadow IT, enhances security, and ensures compliance with organizational policies. The other options (B. VPN concentrator, C. MFA, and D. VPC endpoint) are not directly related to managing or controlling access to SaaS applications, and thus, they would not be the best choice for reducing the risk of unsanctioned high-risk SaaS applications.

A. SaaS is a cloud based service, therefore, a CASB, Cloud Access Security Broker

The best security solution to reduce the risk of shadow IT and unsanctioned high-risk SaaS applications is a Cloud Access Security Broker (CASB). A CASB is a security solution that is designed to provide visibility and control over cloud applications and services. It can be used to block access to unsanctioned applications and to enforce security policies and compliance requirements for cloud services. In this case, the CASB would be used to block access to unsanctioned high-risk SaaS applications, reducing the risk of shadow IT and helping the organization to maintain control over its cloud environment. Options B, C, and D are not specifically related to reducing the risk of shadow IT and unsanctioned SaaS applications. A VPN concentrator is a network device that is used to manage and terminate VPN connections, MFA is a security control that requires multiple factors for authentication, and a VPC endpoint is a networking feature that allows private access to AWS services.
