The CSA STAR registry is a publicly accessible registry that documents the security and privacy controls provided by popular cloud computing offerings1The 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 to1The 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)2The 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 trustworthiness1The 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.

A detective control is a type of internal control that seeks to uncover problems in a company's processes once they have occurred1.Examples of detective controls include physical inventory checks, reviews of account reports and reconciliations, as well as assessments of current controls1.Detective controls use platform telemetry to detect misconfigurations, vulnerabilities, and potentially malicious activity in the cloud environment2.

In a Software as a Service (SaaS) service provider, privileged access monitoring is a detective control that can help identify unauthorized or suspicious activities by users who have elevated permissions to access or modify cloud resources, data, or configurations.Privileged access monitoring can involve logging, auditing, alerting, and reporting on the actions performed by privileged users3. This can help detect security incidents, compliance violations, or operational errors in a timely manner and enable appropriate responses.

Data encryption, incident management, and network segmentation are examples of preventive controls, which are designed to prevent problems from occurring in the first place.Data encryption protects the confidentiality and integrity of data by transforming it into an unreadable format that can only be decrypted with a valid key1.Incident management is a process that aims to restore normal service operations as quickly as possible after a disruption or an adverse event4.Network segmentation divides a network into smaller subnetworks that have different access levels and security policies, reducing the attack surface and limiting the impact of a breach1.

The most useful document for an auditor to review when seeking visibility into the cloud supply chain for a newly acquired Software as a Service (SaaS) solution is the SaaS provider contract.The contract is the legal agreement that defines the terms and conditions of the cloud service, including the roles, responsibilities, and obligations of the parties involved1.The contract should also specify the service level agreements (SLAs), security and privacy requirements, data ownership and governance, incident response and reporting, audit rights and access, and subcontracting or outsourcing arrangements of the SaaS provider2. By reviewing the contract, the auditor can gain insight into the cloud supply chain and assess the risks, controls, and compliance of the SaaS solution.

The other options are not as useful as the SaaS provider contract. Payments made by the service owner are the financial transactions that reflect the fees or charges incurred by using the SaaS solution.They may indicate the usage or consumption of the cloud service, but they do not provide much information about the cloud supply chain or its security and compliance aspects3. SaaS vendor white papers are the marketing or educational materials that describe the features, benefits, or best practices of the SaaS solution.They may provide some general or technical information about the cloud service, but they are not legally binding or verifiable4. Cloud compliance obligations register is a tool that helps customers identify and track their compliance requirements and obligations for using cloud services.It may help customers understand their own responsibilities and risks in relation to the cloud service, but it does not necessarily reflect the compliance status or performance of the SaaS provider5.

Heat maps are graphical representations of data that use color-coding to show the relative intensity, frequency, or magnitude of a variable1. Heat maps can be used to visualize the criticality of the cloud services in an organization, along with their dependencies and risks, by mapping the cloud services to different dimensions, such as business impact, availability, security, performance, cost, etc.Heat maps can help auditors identify the most important or vulnerable cloud services, as well as the relationships and trade-offs among them2.

For example, Azure Charts provides heat maps for various aspects of Azure cloud services, such as updates, trends, pillars, areas, geos, categories, etc3.These heat maps can help auditors understand the current state and dynamics of Azure cloud services and compare them across different dimensions4.

Contractual documents of the cloud service provider are the legal agreements that define the terms and conditions of the cloud service, including the roles, responsibilities, and obligations of the parties involved. They may provide some information on the criticality of the cloud services in an organization, but they are not as visual or comprehensive as heat maps. Data security process flow is a diagram that shows the steps and activities involved in protecting data from unauthorized access, use, modification, or disclosure. It may help auditors understand the data security controls and risks of the cloud services in an organization, but it does not cover other aspects of criticality, such as business impact or performance. Turtle diagram is a tool that helps analyze a process by showing its inputs, outputs, resources, criteria, methods, and interactions. It may help auditors understand the process flow and dependencies of the cloud services in an organization, but it does not show the relative importance or risks of each process element.

Customer management interfaces are the web portals or applications that allow customers to access and manage their cloud services, such as provisioning, monitoring, billing, etc. These interfaces are exposed to the public Internet and may be vulnerable to attacks such as phishing, malware, denial-of-service, or credential theft. If an attacker compromises a customer management interface, they can potentially access and manipulate the customer's cloud resources, data, and configurations, leading to computing and data compromise for customers. This can result in data breaches, service disruptions, unauthorized transactions, or other malicious activities.
