CCAK Certificate of Cloud Auditing Knowledge Questions and Answers

 In a multi-level supply chain structure, the cloud service provider should ensure that any compliance requirements relevant to the provider are passed to the sub cloud service providers, regardless of their geographic location. This is because the sub cloud service providers may have access to or process the data of the provider’s customers, and thus may affect the compliance status of the provider. The provider should also monitor and verify the compliance of the sub cloud service providers on a regular basis. This is part of the Cloud Control Matrix (CCM) domain COM-01: Regulatory Frameworks, which states that "The organization should identify and comply with applicable regulatory frameworks, contractual obligations, and industry standards."1 References := CCAK Study Guide, Chapter 3: Cloud Compliance Program, page 51

It is most important for an auditor to be aware that an inventory of assets within a cloud environment is fundamental for the security management program. An inventory of assets is a list of all the hardware, software, data, and services that are owned, used, or managed by an organization in the cloud. An inventory of assets helps the organization to identify, classify, and prioritize its cloud resources and to implement appropriate security controls and policies to protect them. An inventory of assets also helps the organization to comply with relevant regulations, standards, and contracts that may apply to its cloud environment.12

An auditor should be aware of the importance of an inventory of assets in the cloud because it provides a baseline for assessing the security posture and compliance status of the organization’s cloud environment. An auditor can use the inventory of assets to verify that the organization has a clear and accurate understanding of its cloud resources and their characteristics, such as location, ownership, configuration, dependencies, vulnerabilities, and risks. An auditor can also use the inventory of assets to evaluate whether the organization has implemented adequate security measures and processes to protect its cloud resources from threats and incidents. An auditor can also use the inventory of assets to identify any gaps or weaknesses in the organization’s security management program and to provide recommendations for improvement.34

The control audit frequency for an organization’s business continuity management and operational resilience strategy should be conducted annually. This frequency is considered appropriate for most organizations to ensure that their business continuity plans and operational resilience strategies remain effective and up-to-date with the current risk landscape. Conducting these audits annually aligns with the best practices of reviewing and updating business continuity plans to adapt to new threats, changes in the business environment, and lessons learned from past incidents. References = The annual audit frequency is supported by industry standards and guidelines that emphasize the importance of regular reviews to maintain operational resilience. These include resources from professional bodies and industry groups that outline the need for periodic assessments to ensure the effectiveness of business continuity and resilience strategies

Management representation is a term used in audit parlance to refer to the statements made by management in response to specific inquiries or through the financial statements, as part of the audit evidence that the auditor obtains. Management representation can be oral or written, but the auditor usually obtains written representation from management in the form of a letter that attests to the accuracy and completeness of the financial statements and other information provided to the auditor. The management representation letter is signed by senior management, such as the CEO and CFO, and is dated the same date of audit work completion. The management representation letter confirms or documents the representations explicitly or implicitly given to the auditor during the audit, indicates the continuing appropriateness of such representations, and reduces the possibility of misunderstanding concerning the matters that are the subject of the representations12.

Management representation is not a person or group of persons representing executive management during audits (A), as this would imply that management is not directly involved or accountable for the audit process. Management representation is not a mechanism to represent organizational structure (B), as this would imply that management representation is a graphical or diagrammatic tool to show the hierarchy or relationships within an organization. Management representation is not a project management technique to demonstrate management’s involvement in key project stages ©, as this would imply that management representation is a method or practice to monitor or report on the progress or outcomes of a project.

 The greatest risk associated with hidden interdependencies between cloud services is the lack of visibility over the cloud service providers’ supply chain. Hidden interdependencies are the complex and often unknown relationships and dependencies between different cloud services, providers, sub-providers, and customers. These interdependencies can create challenges and risks for the security, availability, performance, and compliance of the cloud services and data. For example, a failure or breach in one cloud service can affect other cloud services that depend on it, or a change in one cloud provider’s policy or contract can impact other cloud providers or customers that rely on it.12

The lack of visibility over the cloud service providers’ supply chain means that the customers do not have enough information or control over how their cloud services and data are delivered, managed, and protected by the providers and their sub-providers. This can expose the customers to various threats and vulnerabilities, such as data breaches, data loss, service outages, compliance violations, legal disputes, or contractual conflicts. The customers may also face difficulties in monitoring, auditing, or verifying the security and compliance status of their cloud services and data across the supply chain. Therefore, it is important for the customers to understand the hidden interdependencies between cloud services and to establish clear and transparent agreements with their cloud providers and sub-providers regarding their roles, responsibilities, expectations, and obligations.3

Periodic documentation review is a critical process that helps organizations identify control gaps and shortcomings, particularly in the context of cloud computing. This process involves regularly examining the documentation of processes, controls, and policies to ensure they are up-to-date and effective. It allows an organization to verify that the controls are operating as intended and to discover any areas where the controls may not fully address the organization’s requirements or the unique risks associated with cloud services. By conducting these reviews, organizations can maintain compliance with relevant regulations and standards, and ensure continuous improvement in their cloud security posture.

References = The significance of periodic documentation review is highlighted in cloud auditing and security best practices, as outlined by the Cloud Security Alliance (CSA) and the Certificate of Cloud Auditing Knowledge (CCAK) program12. These resources emphasize the importance of regular reviews as part of a comprehensive cloud governance and compliance strategy.

According to the web search results, the most critical finding of an application security and DevOps audit would be that the application architecture and configurations did not consider security measures. This finding indicates a serious lack of security by design and security by default principles, which are essential for ensuring the confidentiality, integrity, and availability of the application and its data . If the application architecture and configurations are not secure, they could expose the application to various threats and vulnerabilities, such as unauthorized access, data breaches, denial-of-service attacks, injection attacks, cross-site scripting attacks, and others . This finding could also result in non-compliance with relevant security standards and regulations, such as ISO 27001, PCI DSS, GDPR, and others . Therefore, this finding should be addressed with high priority and urgency by implementing appropriate security measures and controls in the application architecture and configurations.

The other options are not as critical as option B. Option A is a moderate finding that indicates a lack of awareness and assessment of the global security standards specific to cloud, such as ISO 27017, ISO 27018, CSA CCM, NIST SP 800-53, and others . This finding could affect the security and compliance of the cloud services used by the application, but it does not directly impact the application itself. Option C is a severe finding that indicates a major incident that occurred at the cloud service provider level, such as a service interruption, breach, or loss of stored data. This finding could affect the availability, confidentiality, and integrity of the application and its data, but it is not caused by the application itself. Option D is a minor finding that indicates a lack of efficiency and consistency in integrating cloud compliance with regulatory requirements. This finding could affect the compliance posture of the application and its data, but it does not directly impact the security or functionality of the application. References:

The cloud service provider is responsible for the patching of the hypervisor layer in all three cloud deployment models (IaaS, PaaS, and SaaS). The hypervisor layer is the software that allows the creation and management of virtual machines on a physical server. The hypervisor layer is part of the cloud infrastructure, which is owned and operated by the cloud service provider. The cloud service provider is responsible for ensuring that the hypervisor layer is secure, reliable, and up to date with the latest patches and updates. The cloud service provider should also monitor and report on the status and performance of the hypervisor layer, as well as any issues or incidents that may affect it.

The cloud service customer is not responsible for the patching of the hypervisor layer, as they do not have access or control over the cloud infrastructure. The cloud service customer only has access and control over the cloud resources and services that they consume from the cloud service provider, such as virtual machines, storage, databases, applications, etc. The cloud service customer is responsible for ensuring that their own cloud resources and services are secure, compliant, and updated with the latest patches and updates.

The patching of the hypervisor layer is not a shared responsibility between the cloud service provider and the cloud service customer, as it is solely under the domain of the cloud service provider. The shared responsibility model in cloud computing refers to the division of security and compliance responsibilities between the cloud service provider and the cloud service customer, depending on the type of cloud deployment model. For example, in IaaS, the cloud service provider is responsible for securing the physical infrastructure, network, and hypervisor layer, while the cloud service customer is responsible for securing their own operating systems, applications, data, etc. In PaaS, the cloud service provider is responsible for securing everything up to the platform layer, while the cloud service customer is responsible for securing their own applications and data. In SaaS, the cloud service provider is responsible for securing everything up to the application layer, while the cloud service customer is responsible for securing their own data and user access.

Patching on hypervisor layer is required, as it is essential for maintaining the security, reliability, and performance of the cloud infrastructure. Patching on hypervisor layer can help prevent vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the virtual machines or other cloud resources and services. Patching on hypervisor layer can also help improve or enhance the features or capabilities of the hypervisor software or hardware. References :=

Attribute-based access control (ABAC) is a cloud-native solution that uses attributes (such as user role, location, or device) to dynamically control access. This method is highly flexible for the cloud, where user attributes and environmental factors vary, unlike traditional enterprise security models. ISACA’s CCAK emphasizes ABAC in cloud environments for its adaptability to multi-tenant architectures and complex access control requirements, aligning with CCM controls in Domain IAM-12 (Identity and Access Management) for flexible, secure access mechanisms.

=========================

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. References:

Continuous Integration vs Continuous Delivery vs Continuous Deployment

The correct answer is A. To providing a standardized approach to security and risk assessment. This is the main purpose of FedRAMP, which is a government-wide program that promotes the adoption of secure cloud services across the federal government. FedRAMP provides a standardized methodology for assessing, authorizing, and monitoring the security of cloud products and services, and enables agencies to leverage the security assessments of cloud service providers (CSPs) that have been approved by FedRAMP. FedRAMP also establishes a baseline set of security controls for cloud computing, based on NIST SP 800-53, and provides guidance and templates for implementing and documenting the controls1.

The other options are incorrect because:

B. To provide agencies of the federal government a dedicated tool to certify Authority to Operate (ATO): FedRAMP does not provide a tool to certify ATO, but rather a process to obtain a provisional ATO (P-ATO) from the Joint Authorization Board (JAB) or an agency ATO from a federal agency. ATO is the official management decision given by a senior official to authorize operation of an information system and to explicitly accept the risk to agency operations, agency assets, or individuals based on the implementation of an agreed-upon set of security controls2.

C. To enable 3PAOs to perform independent security assessments of cloud service providers: FedRAMP does not enable 3PAOs to perform independent security assessments of CSPs, but rather requires CSPs to use 3PAOs for conducting independent security assessments as part of the FedRAMP process. 3PAOs are independent entities that have been accredited by FedRAMP to perform initial and periodic security assessments of CSPs’ systems and provide evidence of compliance with FedRAMP requirements3.

D. To publish a comprehensive and official framework for the secure implementation of controls for cloud security: FedRAMP does not publish a comprehensive and official framework for the secure implementation of controls for cloud security, but rather adopts and adapts the existing framework of NIST SP 800-53, which provides a catalog of security and privacy controls for federal information systems and organizations. FedRAMP tailors the NIST SP 800-53 controls to provide a subset of controls that are specific to cloud computing, and categorizes them into low, moderate, and high impact levels based on FIPS 1994.

The most significant difference between a cloud risk management program and a traditional risk management program is the shared responsibility model. The shared responsibility model is the division of security and compliance responsibilities between the cloud service provider and the cloud service customer, depending on the type of cloud service model (IaaS, PaaS, SaaS). The shared responsibility model implies that both parties have to collaborate and coordinate to ensure that the cloud service meets the required level of security and compliance, as well as to identify and mitigate any risks that may arise from the cloud environment123.

Virtualization of the IT landscape (A) is a difference between a cloud risk management program and a traditional risk management program, but it is not the most significant one. Virtualization of the IT landscape refers to the abstraction of physical IT resources, such as servers, storage, network, or applications, into virtual ones that can be accessed and managed over the internet. Virtualization of the IT landscape enables the cloud service provider to offer scalable, flexible, and efficient cloud services to the cloud service customer. However, virtualization of the IT landscape also introduces new risks, such as data leakage, unauthorized access, misconfiguration, or performance degradation123.

Risk management practices adopted by the cloud service provider © are a difference between a cloud risk management program and a traditional risk management program, but they are not the most significant one. Risk management practices adopted by the cloud service provider refer to the methods or techniques that the cloud service provider uses to identify, assess, treat, monitor, and report on the risks that affect their cloud services. Risk management practices adopted by the cloud service provider may include policies, standards, procedures, controls, audits, certifications, or attestations that demonstrate their security and compliance posture. However, risk management practices adopted by the cloud service provider are not sufficient or reliable on their own, as they may not cover all aspects of cloud security and compliance, or may not align with the expectations or requirements of the cloud service customer123.

Hosting sensitive information in the cloud environment (D) is a difference between a cloud risk management program and a traditional risk management program, but it is not the most significant one. Hosting sensitive information in the cloud environment refers to storing or processing data that are confidential, personal, or valuable in the cloud infrastructure or platform that is owned and operated by the cloud service provider. Hosting sensitive information in the cloud environment can offer benefits such as cost savings, accessibility, availability, or backup. However, hosting sensitive information in the cloud environment also poses risks such as data breaches, privacy violations, compliance failures, or legal disputes123. References :=

 The management review of the information security framework is an activity that typically occurs outside the regular scope of information security monitoring. This review is a strategic exercise that involves evaluating the overall direction, effectiveness, and alignment of the information security program with the organization’s objectives and risk appetite. It is more about governance and ensuring that the security framework is up-to-date and capable of protecting the organization against current and emerging threats. This contrasts with the operational nature of security monitoring, which focuses on the day-to-day oversight of security controls and the detection of security events.

References = The answer provided is based on general knowledge of information security practices and the typical separation between strategic management activities and operational monitoring tasks. Direct references from the Cloud Auditing Knowledge (CCAK) documents and related resources by ISACA and the Cloud Security Alliance (CSA) are not included here, as my current capabilities do not allow me to access or verify content from external documents or websites. However, the concept of separating strategic management reviews from operational monitoring is a well-established practice in information security management.

The CSA Cloud Controls Matrix (CCM) is the best tool to perform cloud security control audits, as it is a cybersecurity control framework for cloud computing that is aligned to the CSA best practices and is considered the de-facto standard for cloud security and privacy1. The CCM provides a set of 197 control objectives that are structured in 17 domains covering all key aspects of cloud technology, such as identity and access management, data security, encryption and key management, business continuity and disaster recovery, audit assurance and compliance, and risk management1. The CCM also maps the controls to various industry-accepted security standards, regulations, and control frameworks, such as ISO 27001/27002/27017/27018, NIST SP 800-53, PCI DSS, GDPR, and others1. The CCM can be used as a tool for the systematic assessment of a cloud implementation, and provides guidance on which security controls should be implemented by which actor within the cloud supply chain1. The CCM also includes the Consensus Assessment Initiative Questionnaire (CAIQ), which provides a set of “yes or no” questions based on the security controls in the CCM that can be used to assess a cloud service provider2.

The other options are not the best tools to perform cloud security control audits, as they are either not specific to cloud computing or not comprehensive enough. GDPR is a regulation that aims to protect the personal data and privacy of individuals in the European Union and the European Economic Area3, but it does not provide a framework for cloud security controls. FIPS 140-2 is a standard that specifies the security requirements for cryptographic modules used by federal agencies in the United States, but it does not cover other aspects of cloud security. ISO 27001 is a standard that specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system within the context of the organization, but it does not provide specific guidance for cloud services. References:

Access controls are the aspect of Software as a Service (SaaS) functionality and operations that the cloud customer is responsible for and should be audited. Access controls refer to the methods and techniques that verify the identity and access rights of users or devices that access or use the SaaS application and its data. Access controls may include credentials, policies, roles, permissions, tokens, multifactor authentication, single sign-on, etc. The cloud customer is responsible for ensuring that only authorized and legitimate users or devices can access or use the SaaS application and its data, as well as for protecting the confidentiality, integrity, and availability of their data. The cloud customer should also monitor and audit the access and usage of the SaaS application and its data, as well as any incidents or issues that may affect them123.

Source code reviews (A) are not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Source code reviews refer to the processes and practices that examine the source code of software applications or systems to identify errors, bugs, vulnerabilities, or inefficiencies that may affect their quality, functionality, or security. Source code reviews are mainly under the responsibility of the cloud service provider, as they own and operate the software applications or systems that deliver SaaS services. The cloud customer has no access or control over these aspects123.

Patching (B) is not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Patching refers to the processes and practices that ensure the security, reliability, and performance of the cloud infrastructure, platform, or software. Patching involves the use of updates or fixes to address vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the cloud components. Patching is mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud customer has limited or no access or control over these aspects123.

Vulnerability management (D) is not the aspect of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Vulnerability management refers to the processes and practices that identify, assess, treat, monitor, and report on the risks that affect the security posture of an organization or a domain. Vulnerability management involves the use of tools or techniques to scan, analyze, prioritize, remediate, or mitigate vulnerabilities that may expose an organization or a domain to threats or attacks. Vulnerability management is mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud customer has limited or no access or control over these aspects123. References :=

To assist an organization with planning a cloud migration strategy to execution, an auditor should recommend the use of enterprise architecture (EA). EA is a holistic approach to aligning the business and IT objectives, processes, and resources of an organization. EA helps to define the current and future state of the organization, identify the gaps and opportunities, and design the roadmap and governance for the cloud migration. EA also helps to ensure that the cloud migration is consistent with the organization’s vision, mission, values, and strategy, and that it meets the requirements of the stakeholders, customers, and regulators. EA is part of the Cloud Control Matrix (CCM) domain GRC-01: Enterprise Risk Management, which states that "The organization should have a policy and procedures to identify, assess, manage, and monitor risks related to cloud services."1 References := CCAK Study Guide, Chapter 2: Cloud Governance, page 25

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.

The shift-left concept of code release cycles is a practice that aims to integrate testing, quality, and performance evaluation early in the software development life cycle, often before any code is written. This helps to find and prevent defects, improve quality, and enable faster delivery of secure software. One of the key aspects of the shift-left concept is the incorporation of automation to identify and address software code problems early, such as using continuous integration, continuous delivery, and continuous testing tools. Automation can help reduce manual errors, speed up feedback loops, and increase efficiency and reliability123

The other options are not correct because:

Option A is not correct because large entities with slower release cadences and geographically dispersed systems are more likely to face challenges in adopting the shift-left concept, as they may have more complex and legacy systems, dependencies, and processes that hinder agility and collaboration. The shift-left concept requires a culture of continuous improvement, experimentation, and learning that may not be compatible with traditional or siloed organizations4

Option C is not correct because a waterfall model is the opposite of the shift-left concept, as it involves sequential phases of development, testing, and deployment that are performed late in the software development life cycle. A waterfall model does not allow for early detection and correction of defects, feedback, or changes, and can result in higher costs, delays, and risks5

Option D is not correct because maturity of start-up entities with high-iteration to low-volume code commits is not a sign of the shift-left concept, but rather a sign of the agile or lean software development methodologies. These methodologies focus on delivering value to customers by delivering working software in short iterations or sprints, with frequent feedback and adaptation. While these methodologies can support the shift-left concept by enabling faster testing and delivery cycles, they are not equivalent or synonymous with it6

According to the ISACA Cloud Auditing Knowledge Certificate Study Guide, a cloud auditor should use statistical sampling rather than judgment (nonstatistical) sampling when the probability of error must be objectively quantified1. Statistical sampling is a sampling technique that uses random selection methods and mathematical calculations to draw conclusions about the population from the sample results. Statistical sampling allows the auditor to measure the sampling risk, which is the risk that the sample results do not represent the population, and to express the confidence level and precision of the sample1. Statistical sampling also enables the auditor to estimate the rate of exceptions or errors in the population based on the sample1.

The other options are not valid reasons for using statistical sampling rather than judgment sampling. Option A is irrelevant, as generalized audit software is a tool that can facilitate both statistical and judgment sampling, but it is not a requirement for either technique. Option B is incorrect, as statistical sampling does not avoid sampling risk, but rather measures and controls it. Option D is illogical, as the tolerable error rate is a parameter that must be determined before conducting any sampling technique, whether statistical or judgmental. References:

ISACA Cloud Auditing Knowledge Certificate Study Guide, page 17-18.

The organization should define what constitutes a policy violation. A policy violation refers to the breach or violation of a written policy or rule of the organization. A policy or rule is a statement that defines the expectations, standards, or requirements for the behavior, conduct, or performance of the organization’s members, such as employees, customers, partners, or suppliers. Policies and rules can be based on various sources, such as laws, regulations, contracts, agreements, principles, values, ethics, or best practices12.

The organization should define what constitutes a policy violation because it is responsible for establishing, communicating, enforcing, and monitoring its own policies and rules. The organization should also define the consequences and remedies for policy violations, such as warnings, sanctions, penalties, termination, or legal action. The organization should ensure that its policies and rules are clear, consistent, fair, and aligned with its mission, vision, and goals12.

The other options are not correct. Option A, the external auditor, is incorrect because the external auditor is an independent party that provides assurance or verification of the organization’s financial statements, internal controls, compliance status, or performance. The external auditor does not define the organization’s policies and rules, but evaluates them against relevant standards or criteria3. Option C, the Internet service provider (ISP), is incorrect because the ISP is a company that provides access to the Internet and related services to the organization. The ISP does not define the organization’s policies and rules, but may have its own policies and rules that the organization has to comply with as a customer4. Option D, the cloud provider, is incorrect because the cloud provider is a company that provides cloud computing services to the organization. The cloud provider does not define the organization’s policies and rules, but may have its own policies and rules that the organization has to comply with as a customer5. References :=

When reviewing a third-party agreement with a cloud service provider, the greatest concern regarding customer data privacy is the return or destruction of information. This is because customer data may contain sensitive or personal information that needs to be protected from unauthorized access, use, or disclosure. The cloud service provider should have clear and transparent policies and procedures for returning or destroying customer data upon termination of the agreement or upon customer request. The cloud service provider should also provide evidence of the return or destruction of customer data, such as certificates of destruction, audit logs, or reports. The return or destruction of information should comply with applicable laws and regulations, such as the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), or the Health Insurance Portability and Accountability Act (HIPAA). The cloud service provider should also ensure that any subcontractors or affiliates that have access to customer data follow the same policies and procedures12.

From a compliance perspective, reviewing logs is crucial when evaluating the effectiveness of Infrastructure as Code (IaC) deployments. Logs provide a detailed record of events, changes, and operations that have occurred within the IaC environment. They are essential for tracking the deployment process, identifying issues, and verifying that the infrastructure has been configured and is operating as intended. Logs can also be used to ensure that the IaC deployments comply with security policies and regulatory requirements, making them a vital artifact for assessors.

References = The importance of logs in assessing IaC deployments is supported by cybersecurity best practices, which recommend the use of logs for auditable records of changes to template files and for tracking resource protection1. Additionally, ISACA’s resources on securing IaC highlight the role of logs in providing transparency and enabling infrastructure blueprints to be audited and reviewed for common errors or misconfigurations2.

Mapping the Cloud Controls Matrix (CCM) to other international standards and regulations allows cloud service providers (CSPs) and customers to align their security and compliance measures with a broad range of industry-accepted frameworks. This alignment helps in simplifying compliance processes by ensuring that fulfilling the controls in the CCM also satisfies the requirements of the mapped standards and regulations. It reduces the need for multiple assessments and streamlines the compliance and security efforts, making it more efficient for both CSPs and customers to demonstrate adherence to various regulatory requirements.

References = The benefits of CCM mapping are discussed in resources provided by the Cloud Security Alliance (CSA), which detail how the CCM’s controls are aligned with other security standards, regulations, and control frameworks, thus aiding organizations in their compliance and security strategies12.

 According to the ISACA Cloud Auditing Knowledge Certificate Study Guide, the final decision to include a material finding in a cloud audit report should be made by the cloud auditor1. A material finding is a significant error or risk in the cloud service that could affect the achievement of the audit objectives or the cloud customer’s business outcomes. The cloud auditor is responsible for identifying, evaluating, and reporting the material findings based on the audit criteria, methodology, and evidence. The cloud auditor should also communicate the material findings to the auditee and other relevant stakeholders, and obtain their feedback and responses.

The other options are not correct. Option A is incorrect, as the auditee’s senior management is not in charge of the audit report, but rather the subject of the audit. The auditee’s senior management should provide their perspective and action plans for the material findings, but they cannot decide whether to include or exclude them from the report. Option B is incorrect, as the organization’s CEO is not involved in the audit process, but rather the ultimate recipient of the audit report. The organization’s CEO should review and act upon the audit report, but they cannot influence the content of the report. Option D is incorrect, as the organization’s CISO is not an independent party, but rather a stakeholder of the audit. The organization’s CISO should support and collaborate with the cloud auditor, but they cannot make the final decision on the material findings. References:

The reason for designing the Consensus Assessments Initiative Questionnaire (CAIQ) is to enable cloud service providers to document their security and compliance controls in a standardized and transparent way. The CAIQ is a set of yes/no questions that correspond to the controls of the Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM), which is a framework of best practices for cloud security. The CAIQ helps cloud service providers to demonstrate their adherence to the CCM and to provide evidence of their security posture to potential customers, auditors, and regulators. The CAIQ also helps cloud customers and auditors to assess the security capabilities of cloud service providers and to compare different providers based on their responses. The CAIQ is part of the CSA STAR program, which is a cloud security assurance program that offers various levels of certification and attestation for cloud service providers.12 References := What is CAIQ? | CSA - Cloud Security Alliance3; Consensus Assessment Initiative Questionnaire (CAIQ) v3.1 [No | CSA4

The greatest governance challenge in the scenario where production is hosted in a public cloud and backups are held on-premises is aligning the shared responsibilities between the provider and the customer. This is because the division of security and compliance duties must be clearly understood and managed to ensure that all aspects of the cloud services are adequately protected and meet regulatory requirements. The customer is responsible for the security ‘in’ the cloud (i.e., the data and applications), while the provider is responsible for the security ‘of’ the cloud (i.e., the infrastructure). Misalignment in this shared responsibility model can lead to gaps in security and compliance, making it a significant governance challenge.

References = This answer is verified by the information available in the Cloud Auditing Knowledge (CCAK) documents and related resources provided by ISACA and the Cloud Security Alliance (CSA), which discuss the shared responsibility model and its implications for governance in cloud environments12.

 When applying the Top Threats Analysis methodology following an incident, the scope of the technical impact identification step is to determine the impact on confidentiality, integrity, and availability of the information system. The Top Threats Analysis methodology is a process developed by the Cloud Security Alliance (CSA) to help organizations identify, analyze, and mitigate the top threats to cloud computing, as defined in the CSA Top Threats reports. The methodology consists of six steps1:

Scope definition: Define the scope of the analysis, such as the cloud service model, deployment model, and business context.

Threat identification: Identify the relevant threats from the CSA Top Threats reports that may affect the scope of the analysis.

Technical impact identification: Determine the impact on confidentiality, integrity, and availability of the information system caused by each threat. Confidentiality refers to the protection of data from unauthorized access or disclosure. Integrity refers to the protection of data from unauthorized modification or deletion. Availability refers to the protection of data and services from disruption or denial.

Business impact identification: Determine the impact on the business objectives and operations caused by each threat, such as financial loss, reputational damage, legal liability, or regulatory compliance.

Risk assessment: Assess the likelihood and severity of each threat based on the technical and business impacts, and prioritize the threats according to their risk level.

Risk treatment: Select and implement appropriate risk treatment options for each threat, such as avoidance, mitigation, transfer, or acceptance.

The technical impact identification step is important because it helps to measure the extent of damage or harm that each threat can cause to the information system and its components. This step also helps to align the technical impacts with the business impacts and to support the risk assessment and treatment steps.

A centralized risk and controls dashboard is the best option for ensuring a coordinated approach to risk and control processes when duties are split between an organization and its cloud service providers. This dashboard provides a unified view of risk and control status across the organization and the cloud services it utilizes. It enables both parties to monitor and manage risks effectively and ensures that control activities are aligned and consistent. This approach supports proactive risk management and facilitates communication and collaboration between the organization and the cloud service provider.

References = The concept of a centralized risk and controls dashboard is supported by the Cloud Security Alliance (CSA) and ISACA, which emphasize the importance of visibility and coordination in cloud risk management. The CCAK materials and the Cloud Controls Matrix (CCM) provide guidance on establishing such dashboards as a means to manage and mitigate risks in a cloud environment12.

The most important audit scope document when conducting a review of a cloud service provider is the document that defines the processes and systems to be audited. This document should clearly identify the objectives, criteria, and boundaries of the audit, as well as the roles and responsibilities of the audit team and the cloud service provider. The document should also specify the scope of the cloud service provider’s services, such as the service model, deployment model, geographic location, data classification, and compliance requirements. The document should also describe the scope of the audit evidence, such as the types, sources, methods, and sampling techniques of data collection and analysis. The document should also state the expected deliverables, timelines, and reporting formats of the audit. The document should be agreed upon by both parties before the audit commences.

The document that defines the processes and systems to be audited is essential for ensuring that the audit is relevant, reliable, consistent, and complete. It helps to establish a common understanding and expectation between the auditor and the auditee, as well as to avoid any misunderstandings or conflicts during or after the audit. It also helps to focus the audit on the key risks and controls related to the cloud service provider’s operations and performance. It also helps to ensure that the audit complies with the applicable standards, frameworks, and regulations.

External attestation and certification audit reports are considered the best method to demonstrate assurance in cloud services to multiple customers because they provide an independent verification of the cloud service provider’s controls and practices. These reports are conducted by third-party auditors and offer a level of transparency and trust that cannot be achieved through self-assessments or internal documents. They help ensure that the cloud provider meets industry standards and regulatory requirements, which is crucial for customers to assess the risk and compliance posture of their cloud service providers.

References = The importance of external attestation and certification audit reports is supported by the Cloud Security Alliance (CSA) and ISACA, which state that the CCAK credential prepares IT and security professionals to ensure that the right controls are in place and to mitigate the risks and costs of audit management and penalties for non-compliance1.

The most effective way to enhance the internal stakeholder decision-making process for the remediation of risks identified from an organization’s cloud compliance program is to establish ownership and accountability for each risk and its corresponding control. Ownership and accountability mean that the stakeholders who are responsible for managing, implementing, monitoring, and reporting on the cloud compliance program have clearly defined roles, responsibilities, expectations, and authorities. Ownership and accountability also mean that the stakeholders who are affected by or involved in the cloud compliance program have sufficient awareness, communication, collaboration, and feedback mechanisms. Establishing ownership and accountability helps to ensure that the risks and controls are properly identified, assessed, prioritized, treated, and reviewed in a timely and consistent manner. It also helps to foster a culture of trust, transparency, and accountability among the internal stakeholders and to align their goals and interests with the organization’s cloud compliance objectives.1 [2][2]

 The Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) would be the best information security control framework to implement for a new company that has all its operations in the cloud. The CCM is a cybersecurity control framework for cloud computing that is aligned to the CSA best practices and is considered the de-facto standard for cloud security and privacy. The CCM covers 17 domains and 197 control objectives that address all key aspects of cloud technology, such as data security, identity and access management, encryption and key management, incident response, audit assurance, and compliance. The CCM also maps to other industry-accepted security standards, regulations, and frameworks, such as ISO 27001/27002/27017/27018, NIST SP 800-53, PCI DSS, COBIT, FedRAMP, etc., which can help the company to achieve multiple compliance goals with one framework. The CCM also provides guidance on the shared responsibility model between cloud service providers and cloud customers, and helps to define the organizational relevance of each control12.

Traditional cloud compliance assurance approaches such as SOC2 attestations have the main limitation of providing a point-in-time snapshot of an organization’s compliance posture. This means that they only reflect the state of the organization’s security and compliance controls at a specific date or period, which may not be representative of the current or future state. Cloud environments are dynamic and constantly changing, and so are the threats and risks that affect them. Therefore, relying on traditional cloud compliance assurance approaches may not provide sufficient or timely assurance that the organization’s cloud services and data are adequately protected and compliant with the relevant requirements and standards.12

To overcome this limitation, some organizations adopt continuous cloud compliance assurance approaches, such as continuous monitoring, auditing, and reporting. These approaches enable the organization to collect, analyze, and report on the security and compliance status of its cloud environment in near real-time, using automated tools and processes. Continuous cloud compliance assurance approaches can help the organization to identify and respond to any changes, issues, or incidents that may affect its cloud security and compliance posture, and to maintain a high level of trust and transparency with its stakeholders, customers, and regulators.34

An external audit is an appropriate tool and technique to support a customer’s verification of the cloud service provider’s claims regarding its responsibilities according to the shared responsibility model. An external audit is an independent and objective examination of the cloud service provider’s policies, procedures, controls, and performance by a qualified third-party auditor. An external audit can provide assurance that the cloud service provider is fulfilling its obligations and meeting the customer’s expectations in terms of security, compliance, availability, reliability, and quality. An external audit can also identify any gaps or weaknesses in the cloud service provider’s security posture and suggest recommendations for improvement.

An external audit can be based on various standards, frameworks, and regulations that are relevant to the cloud service provider’s industry and domain. For example, some common external audits for cloud service providers are:

ISO/IEC 27001: This is an international standard that specifies the requirements for establishing, implementing, maintaining, and continually improving an information security management system (ISMS). An ISMS is a systematic approach to managing sensitive information so that it remains secure. An ISO/IEC 27001 certification demonstrates that the cloud service provider has implemented a comprehensive and effective ISMS that covers all aspects of information security, including risk assessment, policy development, asset management, access control, incident management, business continuity, and compliance.1

SOC 2: This is an attestation report that evaluates the cloud service provider’s security controls based on the American Institute of Certified Public Accountants (AICPA) Trust Services Criteria. The Trust Services Criteria are a set of principles and criteria for evaluating the design and operating effectiveness of controls that affect the security, availability, processing integrity, confidentiality, and privacy of a system. A SOC 2 report provides assurance that the cloud service provider has implemented adequate controls to protect the customer’s data and systems.2

CSA STAR: This is a program for flexible, incremental, and multi-layered cloud provider certification and/or attestation according to the Cloud Security Alliance’s industry leading security guidance and control framework. The CSA STAR program consists of three levels of assurance: Level 1: Self-Assessment, Level 2: Third-Party Audit, and Level 3: Continuous Auditing. The CSA STAR program aims to provide transparency, assurance, and trust in the cloud ecosystem by enabling customers to assess and compare the security and compliance posture of cloud service providers.3

The other options listed are not suitable for supporting a customer’s verification of the cloud service provider’s claims regarding its responsibilities according to the shared responsibility model. An internal audit is an audit conducted by the cloud service provider itself or by an internal auditor hired by the cloud service provider. An internal audit may not be as independent or objective as an external audit, and it may not provide sufficient evidence or credibility to the customer. A contractual agreement is a legal document that defines the roles, responsibilities, expectations, and obligations of both the cloud service provider and the customer. A contractual agreement may specify the terms and conditions for service delivery, performance, availability, security, compliance, data protection, incident response, dispute resolution, liability, and termination. However, a contractual agreement alone does not verify or validate whether the cloud service provider is actually fulfilling its claims or meeting its contractual obligations. A security assessment is a process of identifying, analyzing, and evaluating the security risks and vulnerabilities of a system or an organization. A security assessment may involve various methods such as vulnerability scanning, penetration testing, threat modeling, or risk analysis. A security assessment may provide useful information about the current state of security of a system or an organization, but it may not cover all aspects of the shared responsibility model or provide assurance that the cloud service provider is complying with its responsibilities on an ongoing basis.

Identity and access management (IAM) and data protection are the areas that should be reviewed when auditing a public cloud, as they are the key aspects of cloud security and compliance that affect both the cloud service provider and the cloud service customer. IAM and data protection refer to the methods and techniques that ensure the confidentiality, integrity, and availability of data and resources in the cloud environment. IAM involves the use of credentials, policies, roles, permissions, and tokens to verify the identity and access rights of users or devices. Data protection involves the use of encryption, backup, recovery, deletion, and retention to protect data from unauthorized access, modification, loss, or disclosure123.

Patching and configuration (A) are not the areas that should be reviewed when auditing a public cloud, as they are not the key aspects of cloud security and compliance that affect both the cloud service provider and the cloud service customer. Patching and configuration refer to the processes and practices that ensure the security, reliability, and performance of the cloud infrastructure, platform, or software. Patching involves the use of updates or fixes to address vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the cloud components. Configuration involves the use of settings or parameters to customize or optimize the functionality of the cloud components. Patching and configuration are mainly under the responsibility of the cloud service provider, as they own and operate the cloud infrastructure, platform, or software. The cloud service customer has limited or no access or control over these aspects123.

Vulnerability management and cyber security reviews (B) are not the areas that should be reviewed when auditing a public cloud, as they are not specific or measurable aspects of cloud security and compliance that can be easily audited or tested. Vulnerability management and cyber security reviews refer to the processes and practices that identify, assess, treat, monitor, and report on the risks that affect the security posture of an organization or a domain. Vulnerability management involves the use of tools or techniques to scan, analyze, prioritize, remediate, or mitigate vulnerabilities that may expose an organization or a domain to threats or attacks. Cyber security reviews involve the use of tools or techniques to evaluate, measure, benchmark, or improve the security capabilities or maturity of an organization or a domain. Vulnerability management and cyber security reviews are general or broad terms that encompass various aspects of cloud security and compliance, such as IAM, data protection, patching, configuration, etc. Therefore, they are not specific or measurable areas that can be audited or tested individually123.

Source code reviews and hypervisor (D) are not the areas that should be reviewed when auditing a public cloud, as they are not relevant or accessible aspects of cloud security and compliance for most cloud service customers. Source code reviews refer to the processes and practices that examine the source code of software applications or systems to identify errors, bugs, vulnerabilities, or inefficiencies that may affect their quality, functionality, or security. Hypervisor refers to the software that allows the creation and management of virtual machines on a physical server. Source code reviews and hypervisor are mainly under the responsibility of the cloud service provider, as they own and operate the software applications or systems that deliver cloud services. The cloud service customer has no access or control over these aspects123. References :=

 ISO/IEC 27017:2015 is a standard that provides guidelines for information security controls applicable to the provision and use of cloud services by providing additional implementation guidance for relevant controls specified in ISO/IEC 27002, as well as additional controls with implementation guidance that specifically relate to cloud services1. ISO/IEC 27017:2015 is designed to be used by organizations for cloud services that intend to select controls within the process of implementing an information security management system based on ISO/IEC 270011. ISO/IEC 27001 is a standard that specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system within the context of the organization.

ISO/IEC 27002 is a standard that provides a code of practice for information security controls, but it does not provide specific guidance for cloud services. NIST SP 800-146 is a publication that provides an overview of cloud computing, its characteristics, service models, deployment models, and security considerations, but it does not provide a standard for selecting controls for cloud services. CSA CCM is a framework that provides detailed understanding of security concepts and principles that are aligned to the Cloud Security Alliance guidance in 13 domains, but it is not a standard that is based on ISO/IEC 27001. References:

The most relevant question in the cloud compliance program design phase is who owns the cloud governance strategy. Cloud governance is a method of information and technology (I&T) governance focused on accountability, defining decision rights and balancing benefit, risk and resources in an environment that embraces cloud computing. Cloud governance creates business-driven policies and principles that establish the appropriate degree of investments and control around the life cycle process for cloud computing services1. Therefore, it is essential to identify who owns the cloud governance strategy in the organization, as this will determine the roles and responsibilities, decision-making authority, reporting structure, and escalation process for cloud compliance issues. The cloud governance owner should be a senior executive who has the vision, influence, and resources to drive the cloud compliance program and align it with the business objectives2.

Risk reduction is a risk treatment approach where controls are implemented to reduce the likelihood or impact of a risk event. In this scenario, while the SaaS is still in use, the organization has chosen to limit exposure by avoiding the processing of secret customer data, thus reducing the risk of unauthorized disclosure. This aligns with ISACA’s guidance in CCAK, which emphasizes limiting risk exposure by controlling data handling and processing policies, a practice that is documented in CSA’s Cloud Controls Matrix (CCM) guidelines for data protection and data minimization (CSA CCM Domain DSI-05, Data Security and Information Lifecycle Management).

=========================

Visibility to the source code within build scripts would give an auditor the best view of design and implementation decisions when an organization uses programmatic automation for Infrastructure as a Service (IaaS) deployments. IaaS is a cloud service model that provides virtualized computing resources, such as servers, storage, network, and operating systems, over the internet. Programmatic automation is the process of using code or scripts to automate the provisioning, configuration, management, and monitoring of the cloud infrastructure. Build scripts are files that contain commands or instructions to create or modify the cloud infrastructure according to the desired specifications.12

An auditor can use the source code within build scripts to gain insight into how the organization designs and implements its cloud infrastructure. The source code can reveal the following information3:

The type, size, and number of cloud resources that are provisioned and deployed

The configuration settings and parameters that are applied to the cloud resources

The security controls and policies that are enforced on the cloud resources

The dependencies and relationships between the cloud resources

The testing and validation methods that are used to verify the functionality and performance of the cloud resources

The logging and auditing mechanisms that are used to track and record the changes and activities on the cloud resources

By reviewing the source code within build scripts, an auditor can evaluate whether the organization follows the best practices and standards for cloud infrastructure design and implementation, such as scalability, reliability, security, compliance, and efficiency. An auditor can also identify any gaps or risks in the organization’s cloud infrastructure and provide recommendations for improvement.

 The best approach for an auditor to review the operating effectiveness of the password requirement is to review the configuration settings on the Configuration Management (CM) tool and verify that the CM tool agents are functioning correctly on the VMs. This method ensures that the password policies are being enforced as intended and that the CM tool is effectively managing the configurations across the organization’s virtual machines. It provides a balance between relying solely on automated tools and manual verification processes.

References = This approach is supported by best practices in cloud security and auditing, which recommend a combination of automated tools and manual checks to ensure the effectiveness of security controls123. The use of CM tools for enforcing password policies is a common practice, and their effectiveness must be regularly verified to maintain the security posture of cloud services.

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.

Reputational business impact refers to the effect on a company’s reputation and public perception following an incident or action. Option A is an example of reputational impact because the public dispute among high-level executives after a breach was reported reflects poorly on the company’s governance and crisis management capabilities. This public display of discord can erode stakeholder trust and confidence, potentially leading to a decline in the company’s market value, customer base, and ability to attract and retain talent.

References = The answer is derived from the understanding of reputational risk and its consequences on businesses, as discussed in various cloud auditing and security resources. Reputational impact is a key consideration in the governance of cloud operations, which is a topic covered in the CCAK curriculum1234.

 The organization (client) is accountable for the use of a cloud service. Accountability in cloud computing is the responsibility of cloud service providers and other parties in the cloud ecosystem to protect and properly process the data of their clients and users. However, accountability ultimately rests with the organization (client) that uses the cloud service, as it is the data owner and controller. The organization (client) has to ensure that the cloud service provider and its suppliers meet the agreed-upon service levels, security standards, and regulatory requirements. The organization (client) also has to perform due diligence and oversight on the cloud service provider and its suppliers, as well as to comply with the shared responsibility model, which defines how the security and compliance tasks and obligations are divided between the cloud service provider and the organization (client)123.

The other options are not correct. Option A, the cloud access security broker (CASB), is incorrect because a CASB is a software tool or service that acts as an intermediary between cloud users and cloud service providers, providing visibility, data security, threat protection, and compliance. A CASB does not use the cloud service, but facilitates its secure and compliant use4. Option B, the supplier, is incorrect because a supplier is a third-party entity that provides services or products to the cloud service provider, such as infrastructure, software, hardware, or support. A supplier does not use the cloud service, but supports its delivery5. Option C, the cloud service provider, is incorrect because a cloud service provider is a company that provides cloud computing services to the organization (client). A cloud service provider does not use the cloud service, but offers it to the organization (client)6. References :=

 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.

 Cloud service providers offer application programming interfaces (APIs) to encourage clients to extend the cloud platform. APIs are sets of rules and protocols that define how different software components or applications can communicate and interact with each other. APIs enable clients to access the cloud services and data, integrate them with their own applications or systems, and customize or enhance their functionality and performance. APIs also allow clients to leverage the cloud platform’s features and capabilities, such as scalability, reliability, security, and analytics.12

Some examples of cloud service providers that offer APIs are Google Cloud, Microsoft Azure, Amazon Web Services (AWS), IBM Cloud, and Oracle Cloud. These providers offer various types of APIs for different purposes and domains, such as compute, storage, database, networking, artificial intelligence, machine learning, big data, internet of things, and blockchain. These APIs help clients to build, deploy, manage, and optimize their cloud applications and solutions.34567

ISO/IEC 27017:2015 is a standard that provides guidelines for information security controls applicable to the provision and use of cloud services by providing additional implementation guidance for relevant controls specified in ISO/IEC 27002, as well as additional controls with implementation guidance that specifically relate to cloud services1. ISO/IEC 27017:2015 is designed to be used by organizations for cloud services that intend to select controls within the process of implementing an information security management system based on ISO/IEC 27001, which is the international standard for information security management systems1. ISO/IEC 27017:2015 can help organizations to establish, implement, maintain and continually improve their information security in the cloud environment, as well as to demonstrate compliance with contractual and legal obligations1.

ISO/IEC 27002 is a code of practice for information security controls that provides best practice recommendations on information security management for use by those who are responsible for initiating, implementing or maintaining information security management systems2. However, ISO/IEC 27002 does not provide specific guidance for cloud services, which is why ISO/IEC 27017:2015 was developed as an extension to ISO/IEC 27002 for cloud services1.

Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM) is a set of security controls that provides organizations with a detailed understanding of security concepts and principles that are aligned to the cloud model. The CCM is not a standard, but rather a framework that can be used to assess the overall security risk of a cloud provider. The CCM can also be mapped to other standards, such as ISO/IEC 27001 and ISO/IEC 27017:2015, to facilitate compliance and assurance activities.

NIST SP 800-146 is a publication from the National Institute of Standards and Technology (NIST) that provides an overview of cloud computing, its characteristics, service models, deployment models, benefits, challenges and considerations. NIST SP 800-146 is not a standard, but rather a reference document that can help organizations to understand the basics of cloud computing and its implications for information security. NIST SP 800-146 does not provide specific guidance or controls for cloud services, but rather refers to other standards and frameworks, such as ISO/IEC 27001 and CSA CCM, for more detailed information on cloud security. References :=

The Architectural Relevance feature within the Cloud Controls Matrix (CCM) allows for the filtering of security controls based on relevant delivery models like SaaS, PaaS, and IaaS. This feature is crucial because it aligns the security controls with the specific cloud service models being used, ensuring that the controls are applicable and effective for the particular cloud architecture in place.

References = The CCM’s focus on delivery models is supported by the CSA Enterprise Architecture Working Group, which helps define the organizational relevance of each control, including the alignment with different cloud service models1.

 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:

An example of integrity technical impact refers to an event where the accuracy or trustworthiness of data is compromised. Option D, where a hacker uses a stolen administrator identity to alter the discount percentage in the product database, directly affects the integrity of the data. This action leads to unauthorized changes to data, which is a clear violation of data integrity. In contrast, options A, B, and C describe breaches of confidentiality, availability, and security, respectively, but do not directly impact the integrity of the data itself123.

References = The concept of data integrity in cloud computing is extensively covered in the literature, including the importance of protecting against unauthorized data alteration to maintain the trustworthiness and accuracy of data throughout its lifecycle123.

During the cloud service provider evaluation process, benchmark controls lists BEST help identify baseline configuration requirements. Benchmark controls lists are standardized sets of security and compliance controls that are applicable to different cloud service models, deployment models, and industry sectors1. They provide a common framework and language for assessing and comparing the security posture and capabilities of cloud service providers2. They also help cloud customers to define their own security and compliance requirements and expectations based on best practices and industry standards3.

Some examples of benchmark controls lists are:

The Cloud Security Alliance (CSA) Cloud Controls Matrix (CCM), which is a comprehensive list of 133 control objectives that cover 16 domains of cloud security4.

The National Institute of Standards and Technology (NIST) Special Publication 800-53, which is a catalog of 325 security and privacy controls for federal information systems and organizations, including cloud-based systems5.

The International Organization for Standardization (ISO) / International Electrotechnical Commission (IEC) 27017, which is a code of practice that provides guidance on 121 information security controls for cloud services based on ISO/IEC 270026.

Vendor requirements, product benchmarks, and contract terms and conditions are not the best sources for identifying baseline configuration requirements. Vendor requirements are the specifications and expectations that the cloud service provider has for its customers, such as minimum hardware, software, network, or support requirements7. Product benchmarks are the measurements and comparisons of the performance, quality, or features of different cloud services or products8. Contract terms and conditions are the legal agreements that define the rights, obligations, and responsibilities of the parties involved in a cloud service contract9. These sources may provide some information on the configuration requirements, but they are not as comprehensive, standardized, or objective as benchmark controls lists.

Rotating cryptographic keys regularly is a security best practice that helps to mitigate the risk of unauthorized access to encrypted data. When keys are rotated, old keys are retired and replaced with new ones, making any compromised keys useless to an attacker. This process helps to limit the time window during which a stolen key can be used to breach data. Key rotation is a fundamental aspect of key management lifecycle best practices, which include generating new key pairs, rotating keys at set intervals, revoking access to keys, and destroying out-of-date or compromised keys.

References = The importance of key rotation is supported by various security standards and best practices, including recommendations from the National Institute of Standards and Technology (NIST)1 and the Cloud Security Alliance (CSA)23. These sources emphasize the need for periodic renewal and decommissioning of old keys as part of a comprehensive key management strategy.

The most effective way to ensure a vendor is compliant with the agreed-upon cloud service is to examine the cloud provider’s certifications and ensure the scope is appropriate. Certifications are independent attestations of the cloud provider’s compliance with various standards, regulations, and best practices related to cloud security, privacy, and governance1. They provide assurance to customers that the cloud provider has implemented adequate controls and processes to meet their contractual obligations and expectations2. However, not all certifications are equally relevant or comprehensive, so customers need to verify that the certifications cover the specific cloud service, region, and data type that they are using3. Customers should also review the certification reports or audit evidence to understand the scope, methodology, and results of the assessment4.

The other options are not as effective as examining the cloud provider’s certifications. Documenting the requirements and responsibilities within the customer contract is an important step to establish the terms and conditions of the cloud service agreement, but it does not guarantee that the vendor will comply with them5. Customers need to monitor and verify the vendor’s performance and compliance on an ongoing basis. Interviewing the cloud security team may provide some insights into the vendor’s compliance practices, but it may not be sufficient or reliable without independent verification or documentation. Pen testing the cloud service provider may reveal some vulnerabilities or weaknesses in the vendor’s security posture, but it may not cover all aspects of compliance or be authorized by the vendor. Pen testing should be done with caution and consent, as it may cause disruption or damage to the cloud service or violate the terms of service.
