An independent auditor report is a method that can be used by a cloud service provider (CSP) with a cloud customer that does not want to share security and control information. An independent auditor report is a document that provides assurance on the CSP’s security and control environment, based on an audit conducted by a qualified third-party auditor. The audit can be based on various standards or frameworks, such as ISO 27001, SOC 2, CSA STAR, etc. The independent auditor report can provide the cloud customer with the necessary information to evaluate the CSP’s security and control posture, without disclosing sensitive or proprietary details. The CSP can also use the independent auditor report to demonstrate compliance with relevant regulations or contractual obligations.

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.

According to the ISACA Cloud Auditing Knowledge Certificate Study Guide, a cloud auditor should use statistical sampling rather than judgment (nonstatistical) sampling when the probability of error must be objectively quantified1. Statistical sampling is a sampling technique that uses random selection methods and mathematical calculations to draw conclusions about the population from the sample results. Statistical sampling allows the auditor to measure the sampling risk, which is the risk that the sample results do not represent the population, and to express the confidence level and precision of the sample1. Statistical sampling also enables the auditor to estimate the rate of exceptions or errors in the population based on the sample1.

The other options are not valid reasons for using statistical sampling rather than judgment sampling. Option A is irrelevant, as generalized audit software is a tool that can facilitate both statistical and judgment sampling, but it is not a requirement for either technique. Option B is incorrect, as statistical sampling does not avoid sampling risk, but rather measures and controls it. Option D is illogical, as the tolerable error rate is a parameter that must be determined before conducting any sampling technique, whether statistical or judgmental. References:
