 In the context of Infrastructure as a Service (IaaS), a vulnerability assessment will scan virtual machines to identify vulnerabilities in both operating system and application infrastructure contained within the customer’s instances. IaaS is a cloud service model that provides customers with access to virtualized computing resources, such as servers, storage, and networks, hosted by a cloud service provider (CSP). The customer is responsible for installing, configuring, and maintaining the operating system and application software on the virtual machines, while the CSP is responsible for managing the underlying physical infrastructure. Therefore, a vulnerability assessment will scan the customer’s instances to detect any weaknesses or misconfigurations in the operating system and application layers that may expose them to potential threats. A vulnerability assessment can help the customer to prioritize and remediate the identified vulnerabilities, and to comply with relevant security standards and regulations12.

Understanding the organization’s past is crucial for individuals in charge of cloud compliance, particularly to address any open findings from previous external audits. This historical perspective is essential because it allows the compliance team to identify recurring issues, understand the context of past non-compliances, and ensure that corrective actions have been taken and are effective. It also helps in anticipating potential future compliance challenges based on past trends and patterns.

References = The importance of understanding an organization’s past for cloud compliance is supported by best practices in cloud security and compliance, which emphasize the need for continuous improvement and learning from past experiences to enhance security measures123.

 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 :=

 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:

 An example of availability technical impact is a distributed denial of service (DDoS) attack that renders the customer’s cloud inaccessible for 24 hours. Availability technical impact refers to the effect of a cloud security incident on the protection of data and services from disruption or denial. Availability is one of the three security properties of an information system, along with confidentiality and integrity.

Option A is an example of availability technical impact because it shows how a DDoS attack, which is a type of cyberattack that overwhelms a system or network with malicious traffic and prevents legitimate users from accessing it, can cause a severe and prolonged disruption of the customer’s cloud services. Option A also implies that the customer’s organization depends on the availability of its cloud services for its core business operations.

The other options are not examples of availability technical impact. Option B is an example of confidentiality technical impact, which refers to the effect of a cloud security incident on the protection of data from unauthorized access or disclosure. Option B shows how a breach of customer personal data from an unsecured server, which is a type of data leakage or exposure attack that exploits the lack of proper security controls on a system or network, can cause a violation of the privacy and security of the customer’s data. Option C is an example of integrity technical impact, which refers to the effect of a cloud security incident on the protection of data from unauthorized modification or deletion. Option C shows how an administrator inadvertently clicking on phish bait, which is a type of social engineering or phishing attack that tricks a user into clicking on a malicious link or attachment, can expose the company to a ransomware attack, which is a type of malware or encryption attack that locks or encrypts the data and demands a ransom for its release. Option D is also an example of integrity technical impact, as it shows how a hacker using a stolen administrator identity, which is a type of identity theft or impersonation attack that exploits the credentials or privileges of a legitimate user to access or manipulate a system or network, can alter the discount percentage in the product database, which is a type of data tampering or corruption attack that affects the accuracy and reliability of the data. References :=

 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.

Using a standardized control framework enables auditors to conduct gap analyses of what a cloud service provider (CSP) offers versus what the customer requires. A standardized control framework is a set of guidelines, best practices, and criteria that help to evaluate and improve the security, privacy, and compliance of cloud computing environments. Examples of standardized control frameworks include ISO/IEC 27001/27002/27017/27018, NIST SP 800-53, CSA Cloud Controls Matrix (CCM), COBIT, etc. By using a standardized control framework, auditors can compare the CSP’s policies, procedures, and practices with the customer’s expectations and requirements, and identify any gaps or discrepancies that may pose risks or issues. A gap analysis can help the auditors to provide recommendations and suggestions to the CSP and the customer on how to close the gaps and enhance the quality and performance of the cloud services12.

Risk appetite and budget constraints have the most substantial impact on how aggressive or conservative the cloud approach of an organization will be. Risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Budget constraints are the limitations on the financial resources that an organization can allocate to its cloud initiatives. Both factors influence the organization’s strategic decisions on which cloud service models, deployment models, providers, and solutions to adopt, as well as the level of security, compliance, and performance to achieve. An organization with a high risk appetite and a large budget may opt for a more aggressive cloud approach, such as moving critical applications and data to a public cloud provider, while an organization with a low risk appetite and a small budget may opt for a more conservative cloud approach, such as keeping sensitive information on-premises or using a private cloud provider12.

When auditing a public cloud, it is essential to review areas such as Identity and Access Management (IAM) and data protection. IAM involves ensuring that only authorized individuals have access to the cloud resources, and that their access is appropriately managed and monitored. This includes reviewing user authentication methods, access control policies, role-based access controls, and user activity monitoring1.

Data protection is another critical area to review. It involves ensuring that the data stored in the public cloud is secure from unauthorized access, breaches, and leaks. This includes reviewing data encryption methods, data backup and recovery processes, data privacy policies, and compliance with relevant data protection regulations1.

While the other options may also be relevant in certain contexts, they are not as universally applicable as IAM and data protection for auditing a public cloud. Source code reviews and hypervisor (option B), patching and configuration (option C), and vulnerability management and cybersecurity reviews (option D) are important but are more specific to certain types of cloud services or deployment models. References:
