When an organization is moving to the cloud, responsibilities are shared based upon the cloud service provider’s model and accountability is maintained. This means that the organization remains accountable for the security and compliance of its data and applications in the cloud, even if some of the security responsibilities are delegated to the cloud service provider (CSP). The organization cannot transfer or avoid its accountability to the CSP or any other third party, as it is ultimately responsible for its own business outcomes, legal obligations, and reputation. Therefore, the organization must understand the shared responsibility model and which security tasks are handled by the CSP and which tasks are handled by itself. The organization must also monitor and audit the CSP’s performance and security, and mitigate any risks or issues that may arise12.
