 ISO/IEC 15027017 is a cloud-specific security standard that provides guidelines for information security controls applicable to the provision and use of cloud services. It is based on ISO/IEC 27002, which is a general standard for information security management, but it also includes additional controls and implementation guidance that specifically relate to cloud services. ISO/IEC 15027017 is intended to help both cloud service providers and cloud service customers to enhance the security and confidentiality of their cloud environment and to comply with relevant regulatory requirements and industry standards.12 References := ISO/IEC 27017:2015 - Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services1; Cloud Security Standards: ISO, PCI, GDPR and Your Cloud - Exabeam3; ISO/IEC 27017 - Wikipedia2

As an integrity breach. The technical impact of this incident can be categorized as an integrity breach, which refers to the effect of a cloud security incident on the protection of data from unauthorized modification or deletion. Integrity is one of the three security properties of an information system, along with confidentiality and availability.

The incident described in the question involves a cybersecurity criminal finding a vulnerability in an Internet-facing server of an organization, accessing an encrypted file system, and overwriting parts of some files with random data. This is a type of data tampering or corruption attack that affects the accuracy and reliability of the data. The fact that the file system was encrypted does not prevent the integrity breach, as the attacker did not need to decrypt or read the data, but only to overwrite it. The integrity breach can have serious consequences for the organization, such as data loss, data inconsistency, data recovery costs, and loss of trust.

The other options are not correct categories for the technical impact of this incident. Option B, as an availability breach, is incorrect because availability refers to the protection of data and services from disruption or denial, which is not the case in this incident. Option C, as a confidentiality breach, is incorrect because confidentiality refers to the protection of data from unauthorized access or disclosure, which is not the case in this incident. Option D, as a control breach, is incorrect because control refers to the ability to manage or influence the behavior or outcome of a system or process, which is not a security property of an information system. References: =

Supply chain agreements between a cloud service provider and cloud customers should, at a minimum, include audits, assessments, and independent verification of compliance certifications with agreement terms. This is because cloud customers need to ensure that the cloud service provider meets the agreed-upon service levels, security standards, and regulatory requirements. Audits, assessments, and independent verification can provide evidence of the cloud service provider’s compliance and performance and help identify any gaps or risks that need to be addressed. This is also stated in the Practical Guide to Cloud Service Agreements Version 2.012, which is a reference document for cloud customers and providers to analyze and negotiate cloud service agreements.

The other options are not directly related to the question. Option A, regulatory guidelines impacting the cloud customer, refers to the legal and ethical obligations that the cloud customer has to comply with when using cloud services, such as data protection, privacy, and security laws. These guidelines may vary depending on the jurisdiction, industry, and type of data involved. Option C, policies and procedures of the cloud customer, refers to the internal rules and processes that the cloud customer has to follow when using cloud services, such as data governance, access management, and incident response. Option D, the organizational chart of the provider, refers to the structure and hierarchy of the cloud service provider’s organization, such as the roles, responsibilities, and relationships of its employees, departments, and units.

 Access controls are an assurance requirement when an organization is migrating to a SaaS provider because they ensure that only authorized users can access the cloud services and data. Access controls also help to protect the confidentiality, integrity and availability of the cloud resources. Access controls are part of the Cloud Control Matrix (CCM) domain IAM-01: Identity and Access Management Policy and Procedures, which states that "The organization should have a policy and procedures to manage user identities and access to cloud services and data."1 References := CCAK Study Guide, Chapter 4: A Threat Analysis Methodology for Cloud Using CCM, page 751

To ensure a cloud service provider is complying with an organization’s privacy requirements, a cloud auditor should first review the organizational policies, standards, and procedures that define the privacy objectives, expectations, and responsibilities of the organization. The organizational policies, standards, and procedures should also reflect the legal and regulatory requirements that apply to the organization and its cloud service provider, as well as the best practices and guidelines for cloud privacy. The organizational policies, standards, and procedures should provide the basis for evaluating the cloud service provider’s privacy practices and controls, as well as the contractual terms and conditions that govern the cloud service agreement. The cloud auditor should compare the organizational policies, standards, and procedures with the cloud service provider’s self-disclosure statements, third-party audit reports, certifications, attestations, or other evidence of compliance123.

Reviewing the adherence to organization policies, standards, and procedures (B) is a subsequent step that the cloud auditor should perform after reviewing the organizational policies, standards, and procedures themselves. The cloud auditor should assess whether the cloud service provider is following the organization’s policies, standards, and procedures consistently and effectively, as well as whether the organization is monitoring and enforcing the compliance of the cloud service provider. The cloud auditor should also identify any gaps or deviations between the organization’s policies, standards, and procedures and the actual practices and controls of the cloud service provider123.

Reviewing the legal and regulatory requirements © is an important aspect of ensuring a cloud service provider is complying with an organization’s privacy requirements, but it is not the first step that a cloud auditor should take. The legal and regulatory requirements may vary depending on the jurisdiction, industry, or sector of the organization and its cloud service provider. The legal and regulatory requirements may also change over time or be subject to interpretation or dispute. Therefore, the cloud auditor should first review the organizational policies, standards, and procedures that incorporate and translate the legal and regulatory requirements into specific and measurable privacy objectives, expectations, and responsibilities for both parties123.

Reviewing the IT infrastructure (D) is not a relevant or sufficient step for ensuring a cloud service provider is complying with an organization’s privacy requirements. The IT infrastructure refers to the hardware, software, network, and other components that support the delivery of cloud services. The IT infrastructure is only one aspect of cloud security and privacy, and it may not be accessible or visible to the cloud auditor or the organization. The cloud auditor should focus on reviewing the privacy practices and controls that are implemented by the cloud service provider at different layers of the cloud service model (IaaS, PaaS, SaaS), as well as the contractual terms and conditions that define the privacy rights and obligations of both parties123. References :=

 According to the web search results, impact analysis is the aspect of risk management that involves identifying the potential reputational and financial harm when an incident occurs. Impact analysis is the process of assessing the probabilities and consequences of risk events if they are realized1. Impact analysis helps to understand how project outcomes and objectives might change due to the impact of the risk event, and to measure the severity of the risk impact in terms of cost, schedule, quality, and other factors23. Impact analysis also helps to prioritize the risks and plan appropriate responses and controls23.

The other options are not correct. Likelihood is the aspect of risk management that involves estimating the probability or frequency of a risk event occurring23. Mitigation is the aspect of risk management that involves implementing actions or controls to reduce the likelihood or impact of a risk event23. Residual risk is the aspect of risk management that involves measuring the remaining risk after applying mitigation actions or controls23. References:

The auditor’s next course of action should be to review the contract and DR capability of the cloud service provider. The contract should specify the roles and responsibilities of both parties regarding disaster recovery, as well as the service level agreements (SLAs) and recovery time objectives (RTOs) for the critical application. The DR capability should demonstrate that the cloud service provider has a plan that is aligned with the organization’s requirements and expectations, and that it is tested annually and validated by independent auditors. The auditor should also verify that the organization has a process to monitor and review the cloud service provider’s performance and compliance with the contract and SLAs.

Planning an audit of the provider (B) may not be feasible or necessary, as the auditor may not have access to the provider’s environment or data, and may not have the authority or expertise to conduct such an audit. The auditor should rely on the provider’s audit reports and certifications to assess their compliance with relevant standards and regulations.

Reviewing the security white paper of the provider © may not be sufficient or relevant, as the security white paper may not cover the specific aspects of disaster recovery for the critical application, or may not reflect the current state of the provider’s security controls and practices. The security white paper may also be biased or outdated, as it is produced by the provider themselves.

Reviewing the provider’s audit reports (D) may be helpful, but not enough, as the audit reports may not address the specific requirements and expectations of the organization for disaster recovery, or may not cover the latest changes or incidents that may affect the provider’s DR capability. The audit reports may also have limitations or qualifications that may affect their reliability or validity. References :=

In multi-cloud environments, organizations use cloud services from multiple providers. This can lead to challenges in maintaining visibility and control over the data and services due to the varying management tools, processes, and security controls across different providers. The complexity of managing multiple service models and the reliance on different cloud service providers can reduce an organization’s ability to monitor and control its resources effectively, thus increasing the risk of reduced visibility and control.

References = The information aligns with the principles outlined in the CCAK materials, which emphasize the unique challenges of auditing the cloud, including ensuring the right controls for confidentiality, integrity, and accessibility, and mitigating risks such as those associated with multi-cloud environments12.

Reputation-based trust is a category of trust in cloud computing that relies on the feedback, ratings, reviews, or recommendations of other users or third parties who have used or evaluated the cloud service provider or the cloud service. Reputation-based trust reflects the collective opinion and experience of the cloud community regarding the quality, reliability, security, and performance of the cloud service provider or the cloud service. Reputation-based trust can help potential customers to make informed decisions about choosing a cloud service provider or a cloud service based on the reputation score or ranking of the provider or the service. Reputation-based trust can also motivate cloud service providers to improve their services and maintain their reputation by meeting or exceeding customer expectations.

Reputation-based trust is one of the most common and widely used forms of trust in cloud computing, as it is easy to access and understand. However, reputation-based trust also has some limitations and challenges, such as:

The accuracy and validity of the reputation data may depend on the source, method, and frequency of data collection and aggregation. For example, some reputation data may be outdated, incomplete, biased, manipulated, or falsified by malicious actors or competitors.

The interpretation and comparison of the reputation data may vary depending on the context, criteria, and preferences of the customers. For example, some customers may value different aspects of the cloud service more than others, such as security, availability, cost, or functionality.

The trustworthiness and accountability of the reputation system itself may be questionable. For example, some reputation systems may lack transparency, consistency, or standardization in their design, implementation, or operation.

Therefore, reputation-based trust should not be the only factor for trusting a cloud service provider or a cloud service. Customers should also consider other forms of trust in cloud computing, such as evidence-based trust, policy-based trust, or certification-based trust
