The effect of applicable statutory requirements should have priority in planning the scope and objectives of a cloud audit, as they are the mandatory and enforceable rules that govern the cloud service provider and the cloud service customer. Statutory requirements may vary depending on the jurisdiction, industry, or sector of the cloud service provider and the cloud service customer, as well as the type, location, and sensitivity of the data processed or stored in the cloud. Statutory requirements may include laws, regulations, standards, or codes that relate to data protection, privacy, security, compliance, governance, taxation, or liability. The cloud auditor should identify and understand the applicable statutory requirements that affect the cloud service provider and the cloud service customer, and assess whether they are met and adhered to by both parties. The cloud auditor should also verify that the contractual terms and conditions between the cloud service provider and the cloud service customer reflect and comply with the applicable statutory requirements123.
Applicable industry good practices (A) are important for planning the scope and objectives of a cloud audit, but they are not as high priority as applicable statutory requirements. Industry good practices are the recommended or accepted methods or techniques for achieving a desired outcome or result in a specific domain or context. Industry good practices may include frameworks, guidelines, principles, or best practices that are developed by professional bodies, associations, or organizations that have expertise or authority in a certain field or area. Industry good practices may help the cloud service provider and the cloud service customer to improve their performance, quality, efficiency, or effectiveness in delivering or using cloud services. However, industry good practices are not mandatory or enforceable, and they may vary or change over time depending on the evolution of technology or business needs123.
Organizational policies and procedures are important for planning the scope and objectives of a cloud audit, but they are not as high priority as applicable statutory requirements. Organizational policies and procedures are the internal rules and guidelines that define the objectives, expectations, and responsibilities of an organization regarding its operations, activities, processes, or functions. Organizational policies and procedures may include mission statements, vision statements, values statements, strategies, goals, plans, standards, manuals, handbooks, or instructions that are specific to an organization. Organizational policies and procedures may help the organization to align its actions and decisions with its purpose and direction, as well as to ensure consistency and accountability among its members or stakeholders. However, organizational policies and procedures are not mandatory or enforceable outside the organization, and they may differ or conflict among different organizations123.
Applicable corporate standards (D) are important for planning the scope and objectives of a cloud audit, but they are not as high priority as applicable statutory requirements. Corporate standards are the internal rules and guidelines that define the minimum level of quality, performance, reliability, or compatibility that an organization expects from its products, services, processes, or systems. Corporate standards may include specifications, criteria, metrics, indicators, benchmarks, or baselines that are specific to an organization.
Corporate standards may help the organization to measure and evaluate its outputs or outcomes against its objectives or expectations, as well as to identify and address any gaps or issues that may arise. However, corporate standards are not mandatory or enforceable outside the organization, and they may differ or conflict among different organizations123. References :=

The CSA STAR Certification is based on criteria outlined in the Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) in addition to ISO/IEC 27001 implementation. ISO/IEC 27001 is an international standard that specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS). The CSA STAR Certification is a third-party independent assessment of the security of a cloud service provider, which demonstrates the alignment of the provider's ISMS with the CCM best practices. The CSA STAR Certification has three levels: Level 1 (STAR Certification), Level 2 (STAR Attestation), and Level 3 (STAR Continuous Monitoring).1 [2][2] References := CCAK Study Guide, Chapter 5: Cloud Auditing, page 971; CSA STAR Certification, Overview[2][2]

When an organization is moving to the cloud, the first thing to define is the goals of the migration. This is because the goals will guide all subsequent decisions and strategies. Defining clear goals helps in understanding what the organization wants to achieve with cloud migration, whether it's cost savings, scalability, improved performance, or something else. These goals are essential for aligning the migration with the business objectives and for setting the direction for the cloud strategy.
References = The importance of defining the goals of cloud migration is supported by the resources provided by the Cloud Security Alliance (CSA) and ISACA in their Cloud Auditing Knowledge (CCAK) materials12.
These resources emphasize the need for a clear understanding of the objectives and benefits expected from moving to the cloud, which is foundational before delving into specifics such as SLAs, requirements, or provider evaluation criteria.

Continuous integration (CI) is the most critical concept for managing the building and testing of code in DevOps. CI is the practice of merging all developers' working copies of code to a shared mainline several times a day. This enables early detection and resolution of bugs, conflicts, and errors, as well as faster and more frequent feedback loops. CI also facilitates the automation of building, testing, and deploying code, which improves the quality, reliability, and security of the software delivery process. CI is a prerequisite for continuous delivery (CD) and continuous deployment (CD), which are the next stages of DevOps maturity that aim to deliver software to customers faster and more frequently.

The CSA STAR registry is a publicly accessible registry that documents the security and privacy controls provided by popular cloud computing offerings1 The registry is designed for users of cloud services to assess their cloud providers' security and compliance posture, including the regulations, standards, and frameworks they adhere to1 The registry also promotes industry transparency and reduces complexity and costs for both providers and customers2 The provider can direct all customer inquiries to the information in the CSA STAR registry, as this would be the best recommendation to reduce the provider's burden. By publishing to the registry, the provider can show current and potential customers their security and compliance posture, without having to fill out multiple customer questionnaires or requests for proposal (RFPs)2 The provider can also leverage the different levels of assurance available in the registry, such as self-assessment, third-party audit, or certification, to demonstrate their security maturity and trustworthiness1 The provider can also benefit from the CSA Trusted Cloud Providers program, which recognizes providers that have fulfilled additional training and volunteer requirements with CSA, demonstrating their commitment to cloud security competency and industry best practices3 The other options are not correct because:
* Option A is not correct because the provider can schedule a call with each customer is not a good recommendation to reduce the provider's burden. Scheduling a call with each customer would be time-consuming, inefficient, and impractical, especially if the provider receives multiple inquiries and RFPs every month. Scheduling a call would also not guarantee that the customer would be satisfied with the provider's security and compliance posture, as they may still request additional information or evidence. Scheduling a call would also not help the provider differentiate themselves from other providers in the market, as they may not be able to showcase their security maturity and trustworthiness effectively.
* Option B is not correct because the provider can share all security reports with customers to streamline the process is not a good recommendation to reduce the provider's burden. Sharing all security reports with customers may not be feasible, as some reports may contain sensitive or confidential information that should not be disclosed to external parties. Sharing all security reports may also not be desirable, as some reports may be outdated, incomplete, or inconsistent, which could undermine the provider's credibility and reputation. Sharing all security reports may also not be effective, as some customers may not have the expertise or resources to review and understand them properly.
* Option C is not correct because the provider can answer each customer individually is not a good recommendation to reduce the provider's burden. Answering each customer individually would be tedious, repetitive, and costly, as the provider would have to provide similar or identical information to different customers over and over again. Answering each customer individually would also not ensure that the provider's security and compliance posture is consistent and accurate, as they may make mistakes or omissions in their responses. Answering each customer individually would also not help the provider stand out from other providers in the market, as they may not be able to highlight their security achievements and certifications.
