Why is it important for Cloud Service Providers (CSPs) to document security controls?

According to the CSA Security Guidance v4.0 – Domain 1: Cloud Security and Compliance Responsibilities, CSPs are expected to clearly document their internal security controls and customer-facing features to provide transparency and assurance to customers.

“Cloud providers should clearly document their internal security controls and customer security features so the cloud user can make an informed decision. Providers should also properly design and implement those controls.”
