A cloud access security broker (CASB) solution is the best way to enforce access control for an organization that uses multiple cloud technologies, as it provides a centralized and consistent platform to manage and monitor the access to various cloud services and applications. A CASB solution can help to implement and enforce the enterprise's access policies and standards, as well as to detect and prevent unauthorized or malicious access attempts. Senior management support of cloud adoption strategies, creation of a cloud access risk management policy, and expansion of security information and event management (SIEM) to cloud services are not the best ways to enforce access control for an organization that uses multiple cloud technologies, as they do not provide the technical capabilities or tools to manage and monitor the access to various cloud services and applications.

A three lines of defense structure is a model that defines the roles and responsibilities of different functions and levels within an organization for risk management and control. The first line of defense is the operational management, which is responsible for owning and managing the risks. The second line of defense is the risk management and compliance functions, which are responsible for overseeing and supporting the risk management processes. The third line of defense is the internal audit function, which is responsible for providing independent assurance on the effectiveness of the risk management and control systems. The greatest benefit of a three lines of defense structure is that it provides clear accountability for risk management processes, as it clarifies who is responsible for what, and how they interact and communicate with each other.
This can help to avoid duplication, confusion, or gaps in the risk management activities, and ensure that the risks are properly identified, assessed, treated, monitored, and reported. References = CRISC Review Manual,

Policies and standards are the primary documents that define the organization's expectations and requirements for information security and risk management. They provide the basis for establishing controls, procedures, roles, and responsibilities. Policies and standards should be updated following a change in legislation requiring notification to individuals impacted by data breaches, to ensure compliance with the new legal obligations and to align with the organization's risk appetite and tolerance. Updating policies and standards can also help to communicate the changes to the relevant stakeholders and to provide guidance for implementing and monitoring the controls.
