Which of the following is the PRIMARY area for an auditor to examine in order to understand the criticality of the cloud services in an organization, along with their dependencies and risks?
Correct Answer: B
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.

Question 122
To support a customer's verification of the cloud service provider claims regarding its responsibilities according to the shared responsibility model, which of the following tools and techniques is appropriate?
Correct Answer: A
Explanation 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.

Correct Answer: B
Question 124
Which of the following is the BEST tool to perform cloud security control audits?
Correct Answer: A
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.

Question 125
What do cloud service providers offer to encourage clients to extend the cloud platform?
Correct Answer: D
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 References := What is an API? - Definition from WhatIs.com1; What is a Cloud API? - Definition from Techopedia2; Cloud APIs | Google Cloud3; Cloud Services - Deploy Cloud Apps & APIs | Microsoft Azure4; AWS Application Programming Interface (API) | AWS5; IBM Cloud API Docs6; Oracle Cloud Infrastructure API Documentation
