This is the best method to review and assess the security of the cloud service models used by a company on multiple CSPs. CSP stands for cloud service provider, which is a company that offers cloud-based services such as infrastructure, platform, or software. CASB stands for cloud access security broker, which is a software or service that acts as a gateway between the company and the CSPs, and provides visibility, control, compliance, and threat protection for the cloud services.
Integrating the security benchmarks of the CSPs with a CASB means that the company can use a common set of standards and metrics to measure and compare the security posture and performance of different cloud service models, such as IaaS, PaaS, or SaaS. Security benchmarks are predefined criteria or best practices that define the minimum level of security required for a cloud service model. For example, some security benchmarks may include encryption, authentication, logging, auditing, patching, backup, etc. By integrating these benchmarks with a CASB, the company can monitor and enforce them across multiple CSPs, and identify any gaps or risks in their cloud security.
