 An auditor examining a cloud service provider’s SLA should be most concerned about whether the agreement excludes any operational matters that are material to the service operations, as this could indicate a lack of transparency, accountability, and quality assurance from the provider. Operational matters are the aspects of the cloud service that affect its functionality, performance, availability, reliability, security, and compliance. Examples of operational matters include service scope, roles and responsibilities, service levels and metrics, monitoring and reporting mechanisms, incident and problem management, change management, backup and recovery, data protection and privacy, and termination and exit clauses12. These matters are material to the service operations if they have a significant impact on the achievement of the service objectives and expectations of the cloud customer. The auditor should verify that the SLA covers all the relevant and material operational matters in a clear and comprehensive manner, and that the provider adheres to the SLA terms and conditions.

The other options are not the most concerning for the auditor. Option A is a desirable feature of an SLA, but not a concern if it is missing. Option B is an unrealistic expectation of an SLA, as sourcing and financial matters are usually essential in meeting the SLA. Option C is a specific example of an operational matter that is material to the service operations, but not the only one that should be included in the SLA. References:

Cloud Computing: Agencies Need to Incorporate Key Practices to Ensure Effective Performance

To qualify for CSA STAR attestation, the SOC 2 report must cover both the Cloud Controls Matrix (CCM) and ISO/IEC 27001:2013 controls. The CSA STAR Attestation integrates SOC 2 reporting with additional cloud security criteria from the CSA CCM. This combination provides a comprehensive framework for assessing the security and privacy controls of cloud services, ensuring that they meet the rigorous standards required for STAR attestation. References = The information is supported by the Cloud Security Alliance’s resources, which outline the STAR program’s emphasis on transparency, rigorous auditing, and harmonization of standards as per the CCM. Additionally, the CSA STAR Certification process leverages the requirements of the ISO/IEC 27001:2013 management system standard together with the CSA Cloud Controls Matrix

One possible reason why the results of third-party audits and certification should be relied on when analyzing and assessing the cybersecurity risks in the cloud is to contrast the risk generated by the loss of control. When an organization moves its data and processes to the cloud, it inevitably loses some degree of control over its security and compliance posture, as it depends on the cloud service provider (CSP) to implement and maintain adequate security measures and controls1 This loss of control can increase the organization’s exposure to various cybersecurity risks, such as data breaches, unauthorized access, denial of service, malware infection, etc2

To mitigate these risks, the organization needs to have a clear understanding of the security and compliance level of the CSP, as well as the shared responsibility model that defines the roles and responsibilities of both parties3 Third-party audits and certification can provide some level of assurance that the CSP meets certain standards and requirements related to security and compliance, such as ISO/IEC 27001, CSA STAR, SOC 2, etc. These audits and certification can also help the organization compare and contrast the security posture of different CSPs in the market, as well as identify any gaps or weaknesses that need to be addressed or compensated.

Therefore, relying on the results of third-party audits and certification can help the organization contrast the risk generated by the loss of control in the cloud, and make informed decisions about selecting and managing its cloud services.
