 A dot release of the Cloud Controls Matrix (CCM) indicates a technical change (revision, addition, or deletion) of a number of controls that is smaller than 10% compared to the previous full release. A dot release is a minor update to the CCM that reflects the feedback from the cloud security community and the changes in the cloud technology landscape. A dot release does not change the domain structure or the overall scope of the CCM, but rather improves the clarity, accuracy, and relevance of the existing controls. A dot release is denoted by a decimal number after the major version number, such as CCM v4.1 or CCM v4.2. The current version of the CCM is v4.0, which was released in October 20211.

The other options are incorrect because:

A. a revision of the CCM domain structure: A revision of the CCM domain structure is a major change that affects the organization and categorization of the controls into different domains. A revision of the CCM domain structure requires a full release, not a dot release, and is denoted by an integer number, such as CCM v3 or CCM v42.

C. the introduction of new control frameworks mapped to previously published CCM controls: The introduction of new control frameworks mapped to previously published CCM controls is an additional feature that enhances the usability and applicability of the CCM. The introduction of new control frameworks mapped to previously published CCM controls does not require a dot release or a full release, but rather an update to the mapping table that shows the relationship between the CCM controls and other industry-accepted security standards, regulations, and frameworks3.

D. technical change (revision, addition, or deletion) of a number of controls that is greater than 10% compared to the previous full release: A technical change (revision, addition, or deletion) of a number of controls that is greater than 10% compared to the previous full release is a significant change that affects the content and scope of the CCM. A technical change (revision, addition, or deletion) of a number of controls that is greater than 10% compared to the previous full release requires a full release, not a dot release, and is denoted by an integer number, such as CCM v3 or CCM v42.

Cloud Security Alliance Releases New Cloud Controls Matrix Auditing Guidelines

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.

The Cloud Controls Matrix (CCM) by the Cloud Security Alliance provides a comprehensive control framework that aligns with industry standards, regulations, and best practices, offering a structured approach for cloud security and compliance management. This mapping capability makes it highly valuable in cloud audits as noted in the CCAK, which relies on CCM for its comprehensive applicability in regulatory compliance and security (referenced in CSA CCM V4 documentation and ISACA CCAK content).

According to the CSA website, the primary purpose of the Open Certification Framework (OCF) for the CSA STAR program is to provide global, accredited, trusted certification of cloud providers1 The OCF is an industry initiative to allow global, trusted independent evaluation of cloud providers. It 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 framework2 The OCF aims to address the gaps within the IT ecosystem that are inhibiting market adoption of secure and reliable cloud services, such as the lack of simple, cost effective ways to evaluate and compare providers’ resilience, data protection, privacy, and service portability2 The OCF also aims to promote industry transparency and reduce complexity and costs for both providers and customers3

The other options are not correct because:

Option A is not correct because facilitating an effective relationship between the cloud service provider and cloud client is not the primary purpose of the OCF for the CSA STAR program, but rather a potential benefit or outcome of it. The OCF can help facilitate an effective relationship between the provider and the client by providing a common language and framework for assessing and communicating the security and compliance posture of the provider, as well as enabling trust and confidence in the provider’s capabilities and performance. However, this is not the main goal or objective of the OCF, but rather a means to achieve it.

Option B is not correct because ensuring understanding of true risk and perceived risk by the cloud service users is not the primary purpose of the OCF for the CSA STAR program, but rather a possible implication or consequence of it. The OCF can help ensure understanding of true risk and perceived risk by the cloud service users by providing objective and verifiable information and evidence about the provider’s security and compliance level, as well as allowing comparison and benchmarking with other providers in the market. However, this is not the main aim or intention of the OCF, but rather a result or effect of it.

Option D is not correct because enabling the cloud service provider to prioritize resources to meet its own requirements is not the primary purpose of the OCF for the CSA STAR program, but rather a potential advantage or opportunity for it. The OCF can enable the cloud service provider to prioritize resources to meet its own requirements by providing a flexible, incremental and multi-layered approach to certification and/or attestation that allows the provider to choose the level of assurance that suits their business needs and goals. However, this is not the main reason or motivation for the OCF, but rather a benefit or option for it.

According to the CCAK Study Guide, the business continuity management and operational resilience strategy of the cloud customer should be formulated jointly with the cloud service provider, as they share the responsibility for ensuring the availability and recoverability of the cloud services. The strategy should cover all aspects of business continuity and resilience planning, taking inputs from the assessed impact and risks, to consider activities for before, during, and after a disruption. These activities include prevention, mitigation, response, recovery, restoration, and improvement. The strategy should also define the roles and responsibilities of both parties, the communication channels and escalation procedures, the testing and exercising plans, and the review and update mechanisms1

The other options are not correct because:

Option B is not correct because the strategy should not only be developed within the acceptable limits of the risk appetite, but also aligned with the business objectives and stakeholder expectations of both parties. The risk appetite is only one of the factors that influence the strategy formulation1

Option C is not correct because the strategy should not only cover the activities required to continue and recover prioritized activities within identified time frames and agreed capacity, but also consider the activities for before and after a disruption, such as prevention, mitigation, improvement, etc. The strategy should also include other elements such as roles and responsibilities, communication channels, testing plans, etc1

 The objective that is most appropriate to measure the effectiveness of password policy is newly created account credentials satisfy requirements. This is because password policy is a set of rules and guidelines that define the characteristics and usage of passwords in a system or network. Password policy aims to enhance the security and confidentiality of the system or network by preventing unauthorized access, data breaches, and identity theft. Therefore, the best way to evaluate the effectiveness of password policy is to check whether the newly created account credentials meet the requirements of the policy, such as length, complexity, expiration, and history. This objective can be measured by conducting periodic audits, reviews, or tests of the account creation process and verifying that the passwords comply with the policy standards. This is part of the Cloud Control Matrix (CCM) domain IAM-02: User ID Credentials, which states that "The organization should have a policy and procedures to manage user ID credentials for cloud services and data."1 References := CCAK Study Guide, Chapter 4: A Threat Analysis Methodology for Cloud Using CCM, page 76

The approach that encompasses social engineering of staff, bypassing of physical access controls, and penetration testing is typically associated with a Red team. A Red team is designed to simulate real-world attacks to test the effectiveness of security measures. They often use tactics like social engineering and penetration testing to identify vulnerabilities. In contrast, a Blue team is responsible for defending against attacks, a White box approach involves testing with internal knowledge of the system, and a Gray box is a combination of both White box and Black box testing methods.

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
