A customer has a contract with a CSP and wants to identify which controls should be implemented in the IaaS enclave. Which of the following is most likely to contain this information?

The statement of work (SOW) is primarily focused on outlining the specific tasks, deliverables, and timelines for a project. While it may reference certain controls, it does not typically provide a detailed breakdown of responsibilities related to security controls in the IaaS environment, making it less suitable for identifying which controls should be implemented.

A service-level agreement (SLA) defines the level of service expected from the CSP, including performance metrics and availability guarantees. However, it does not specify the individual controls that need to be implemented in the IaaS enclave, focusing instead on the overall service quality and obligations rather than security responsibilities.

The master service agreement (MSA) serves as a comprehensive contract between the customer and the CSP, detailing various terms and conditions of the service relationship. While it may cover security obligations in a general sense, it does not provide the specific breakdown of responsibilities for implementing controls within the IaaS enclave, unlike the responsibility matrix.
