Implementing service level agreements (SLAs) around changes to baseline configurations is the most important way to manage risk from cloud vendors who might accidentally introduce unnecessary risk to an organization by adding new features to their solutions. A service level agreement (SLA) is a contract or a part of a contract that defines the expected level of service, performance, and quality that a cloud vendor will provide to an organization. An SLA can also specify the roles and responsibilities, the communication channels, the escalation procedures, and the penalties or remedies for non-compliance12.
Implementing SLAs around changes to baseline configurations can help an organization to manage the risk from cloud vendors who might add new features to their solutions without proper testing, validation, or notification. Baseline configurations are the standard or reference settings for a system or a network that are used to measure and maintain its security and performance. Changes to baseline configurations can introduce new vulnerabilities, errors, or incompatibilities that can affect the functionality, availability, or security of the system or network34. Therefore, an SLA can help an organization to ensure that the cloud vendor follows a change management process that includes steps such as risk assessment, impact analysis, approval, documentation, notification, testing, and rollback. An SLA can also help an organization to monitor and verify the changes made by the cloud vendor and to report and resolve any issues or incidents that may arise from them.
The other options are not the most effective ways to manage the risk from cloud vendors who might add new features to their solutions. Option A, deploying new features using cloud orchestration tools, is not a good way to manage the risk because cloud orchestration tools are used to automate and coordinate the deployment and management of complex cloud services and resources. Cloud orchestration tools do not address the issue of whether the new features added by the cloud vendor are necessary, secure, or compatible with the organization’s system or network. Option B, performing prior due diligence of the vendor, is not a good way to manage the risk because prior due diligence is a process that involves evaluating and verifying the background, reputation, capabilities, and compliance of a potential cloud vendor before entering into a contract with them. Prior due diligence does not address the issue of how the cloud vendor will handle changes to their solutions after the contract is signed. Option C, establishing responsibility in the vendor contract, is not a good way to manage the risk because establishing responsibility in the vendor contract is a process that involves defining and assigning the roles and obligations of both parties in relation to the cloud service delivery and performance. Establishing responsibility in the vendor contract does not address the issue of how the cloud vendor will communicate and coordinate with the organization about changes to their solutions.
