Which of the following is a category of trust in cloud computing?

1. A. Loyalty-based trust
2. B. Background-based trust
3. C. Reputation-based trust
4. D. Transparency-based trust

Correct Answer: C
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 For example, some reputation data may be outdated, incomplete, biased, manipulated, or falsified by malicious actors or competitors.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

A business unit introducing cloud technologies to the organization without the knowledge or approval of the appropriate governance function is an example of:

1. A. IT exception
2. B. Threat
3. C. Shadow IT
4. D. Vulnerability

Correct Answer: C
Shadow IT refers to the use of IT resources (hardware, software, or cloud services) within an organization without the explicit approval of the IT or governance team. This practice is often flagged in cloud audits due to potential risks of compliance violations and security threats. The CCAK documentation from ISACA highlights the need for visibility and governance over all IT assets, with specific controls listed in the CSA CCM for Cloud Governance (GOV-09). Shadow IT poses risks to data security, compliance, and can introduce vulnerabilities, as systems are not subject to organizational standards and oversight.

Which of the following has the MOST substantial impact on how aggressive or conservative the cloud approach of an organization will be?

1. A. Applicable laws and regulations
2. B. Internal policies and technical standards
3. C. Risk scoring criteria
4. D. Risk appetite and budget constraints

Correct Answer: D
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.

To ensure a cloud service provider is complying with an organization's privacy requirements, a cloud auditor should FIRST review:

1. A. organizational policies, standards, and procedures.
2. B. adherence to organization policies, standards, and procedures.
3. C. legal and regulatory requirements.
4. D. the IT infrastructure.

Correct Answer: A
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.

Which of the following is an example of availability technical impact?

1. A. A distributed denial of service (DDoS) attack renders the customer's cloud inaccessible for 24 hours.
2. B. The cloud provider reports a breach of customer personal data from an unsecured server.
3. C. An administrator inadvertently clicked on phish bait, exposing the company to a ransomware attack.
4. D. A hacker using a stolen administrator identity alters the discount percentage in the product database

Correct Answer: A
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.
