One possible reason why the results of third-party audits and certification should be relied on when analyzing and assessing the cybersecurity risks in the cloud is to contrast the risk generated by the loss of control. When an organization moves its data and processes to the cloud, it inevitably loses some degree of control over its security and compliance posture, as it depends on the cloud service provider (CSP) to implement and maintain adequate security measures and controls1 This loss of control can increase the organization’s exposure to various cybersecurity risks, such as data breaches, unauthorized access, denial of service, malware infection, etc2

To mitigate these risks, the organization needs to have a clear understanding of the security and compliance level of the CSP, as well as the shared responsibility model that defines the roles and responsibilities of both parties3 Third-party audits and certification can provide some level of assurance that the CSP meets certain standards and requirements related to security and compliance, such as ISO/IEC 27001, CSA STAR, SOC 2, etc. These audits and certification can also help the organization compare and contrast the security posture of different CSPs in the market, as well as identify any gaps or weaknesses that need to be addressed or compensated.

Therefore, relying on the results of third-party audits and certification can help the organization contrast the risk generated by the loss of control in the cloud, and make informed decisions about selecting and managing its cloud services.

Visibility to the source code within build scripts would give an auditor the best view of design and implementation decisions when an organization uses programmatic automation for Infrastructure as a Service (IaaS) deployments. IaaS is a cloud service model that provides virtualized computing resources, such as servers, storage, network, and operating systems, over the internet. Programmatic automation is the process of using code or scripts to automate the provisioning, configuration, management, and monitoring of the cloud infrastructure. Build scripts are files that contain commands or instructions to create or modify the cloud infrastructure according to the desired specifications.12

An auditor can use the source code within build scripts to gain insight into how the organization designs and implements its cloud infrastructure. The source code can reveal the following information3:

The type, size, and number of cloud resources that are provisioned and deployed

The configuration settings and parameters that are applied to the cloud resources

The security controls and policies that are enforced on the cloud resources

The dependencies and relationships between the cloud resources

The testing and validation methods that are used to verify the functionality and performance of the cloud resources

The logging and auditing mechanisms that are used to track and record the changes and activities on the cloud resources

By reviewing the source code within build scripts, an auditor can evaluate whether the organization follows the best practices and standards for cloud infrastructure design and implementation, such as scalability, reliability, security, compliance, and efficiency. An auditor can also identify any gaps or risks in the organization’s cloud infrastructure and provide recommendations for improvement.

A SOC 2 Type 2 report is the most comprehensive type of report for cloud service providers, as it evaluates the design and operating effectiveness of a service organization’s controls over a period of time. This type of report is specifically intended to meet the needs of customers who need assurance about the security, availability, processing integrity, confidentiality, or privacy of the data processed by the service provider1234.

References = The importance of SOC 2 Type 2 reports for cloud service providers is discussed in various resources, including those provided by ISACA and the Cloud Security Alliance, which highlight the need for such reports to ensure the operating effectiveness of controls5678.

A corrective control is a measure taken to correct or reduce the impact of an error, deviation, or unwanted activity1. Corrective control can be either manual or automated, depending on the type of control used. Corrective control can involve procedures, manuals, systems, patches, quarantines, terminations, reboots, or default dates1. A Business Continuity Plan (BCP) is an example of a corrective control.

Unsuccessful access attempts being automatically logged for investigation is an example of a corrective control because it is a response to a potential security incident that aims to identify and resolve the cause and prevent future occurrences2. Logging and investigating failed login attempts can help detect unauthorized or malicious attempts to access sensitive data or systems and take appropriate actions to mitigate the risk.

The other options are examples of preventive controls, which are designed to prevent problems from occurring in the first place3. Preventive controls can include:

A central antivirus system installing the latest signature files before allowing a connection to the network: This is a preventive control because it prevents malware infection by blocking potentially harmful connections and updating the antivirus software regularly4.

All new employees having standard access rights until their manager approves privileged rights: This is a preventive control because it prevents unauthorized access by enforcing the principle of least privilege and requiring approval for granting higher-level permissions5.

Privileged access to critical information systems requiring a second factor of authentication using a soft token: This is a preventive control because it prevents credential theft or compromise by adding an extra layer of security to verify the identity of the user.

The control audit frequency for an organization’s business continuity management and operational resilience strategy should be conducted annually. This frequency is considered appropriate for most organizations to ensure that their business continuity plans and operational resilience strategies remain effective and up-to-date with the current risk landscape. Conducting these audits annually aligns with the best practices of reviewing and updating business continuity plans to adapt to new threats, changes in the business environment, and lessons learned from past incidents. References = The annual audit frequency is supported by industry standards and guidelines that emphasize the importance of regular reviews to maintain operational resilience. These include resources from professional bodies and industry groups that outline the need for periodic assessments to ensure the effectiveness of business continuity and resilience strategies

Role-based access controls (RBAC) are a method of restricting access to resources based on the roles of individual users within an organization. RBAC allows administrators to assign permissions to roles, rather than to specific users, and then assign users to those roles. This simplifies the management of access rights and reduces the risk of unauthorized or excessive access. RBAC is especially important for ensuring adequate restriction on the number of people who can access the pipeline production environment, which is the final stage of the continuous integration and continuous delivery (CI/CD) process where code is deployed to the end-users. Access to the production environment should be limited to only those who are responsible for deploying, monitoring, and maintaining the code, such as production engineers, release managers, or site reliability engineers. Developers, testers, or other stakeholders should not have access to the production environment, as this could compromise the security, quality, and performance of the code. RBAC can help enforce this separation of duties and responsibilities by defining different roles for different pipeline stages and granting appropriate permissions to each role. For example, developers may have permission to create, edit, and test code in the development pipeline, but not to deploy or modify code in the production pipeline. Conversely, production engineers may have permission to deploy, monitor, and troubleshoot code in the production pipeline, but not to create or edit code in the development pipeline. RBAC can also help implement the principle of least privilege, which states that users should only have the minimum level of access required to perform their tasks. This reduces the attack surface and minimizes the potential damage in case of a breach or misuse. RBAC can be configured at different levels of granularity, such as at the organization, project, or object level, depending on the needs and complexity of the organization. RBAC can also leverage existing identity and access management (IAM) solutions, such as Azure Active Directory or AWS IAM, to integrate with cloud services and applications.

Cloud Computing — What IT Auditors Should Really Know

 According to the cloud shared responsibility model, the cloud customer is responsible for managing the access controls for the SaaS functionality and operations, and this should be audited by the cloud auditor12. Access controls are the mechanisms that restrict and regulate who can access and use the SaaS applications and data, and how they can do so. Access controls include identity and access management, authentication, authorization, encryption, logging, and monitoring. The cloud customer is responsible for defining and enforcing the access policies, roles, and permissions for the SaaS users, as well as ensuring that the access controls are aligned with the security and compliance requirements of the customer’s business context12.

The other options are not the aspects of SaaS functionality and operations that the cloud customer is responsible for and should be audited. Option B is incorrect, as vulnerability management is the process of identifying, assessing, and mitigating the security weaknesses in the SaaS applications and infrastructure, and this is usually handled by the cloud service provider12. Option C is incorrect, as patching is the process of updating and fixing the SaaS applications and infrastructure to address security issues or improve performance, and this is also usually handled by the cloud service provider12. Option D is incorrect, as source code reviews are the process of examining and testing the SaaS applications’ source code to detect errors or vulnerabilities, and this is also usually handled by the cloud service provider12. References:

External attestation and certification audit reports are considered the best method to demonstrate assurance in cloud services to multiple customers because they provide an independent verification of the cloud service provider’s controls and practices. These reports are conducted by third-party auditors and offer a level of transparency and trust that cannot be achieved through self-assessments or internal documents. They help ensure that the cloud provider meets industry standards and regulatory requirements, which is crucial for customers to assess the risk and compliance posture of their cloud service providers.

References = The importance of external attestation and certification audit reports is supported by the Cloud Security Alliance (CSA) and ISACA, which state that the CCAK credential prepares IT and security professionals to ensure that the right controls are in place and to mitigate the risks and costs of audit management and penalties for non-compliance1.

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 best way for the organization to take advantage of the supplier relationship feature of the Cloud Controls Matrix (CCM) is to leverage this feature to enable a smarter selection of the next cloud provider. The supplier relationship feature is a column in the CCM spreadsheet that indicates whether a control is influenced by contractual agreements between the cloud service provider and the cloud customer. This feature can help the organization to identify and compare the security and compliance capabilities of different cloud providers, as well as to negotiate and customize the terms of service (TOS) and service level agreements (SLA) according to their needs and requirements123.

The other options are not the best ways to use the supplier relationship feature. Option A, filter out only those controls directly influenced by contractual agreements, is not a good way to use the feature because it would exclude other important controls that are not influenced by contractual agreements, but still relevant for cloud security and governance. Option B, leverage this feature to enable the adoption of the Shared Responsibility Model, is not a good way to use the feature because the Shared Responsibility Model is defined by another column in the CCM spreadsheet, which indicates whether a control is applicable to the cloud service provider or the cloud customer. Option C, filter out only those controls having a direct impact on current TOS and SLA, is not a good way to use the feature because it would exclude other controls that may have an indirect or potential impact on the TOS and SLA, or that may be subject to change or negotiation in the future. References :=
