The shift-left concept of code release cycles is a practice that aims to integrate testing, quality, and performance evaluation early in the software development life cycle, often before any code is written. This helps to find and prevent defects, improve quality, and enable faster delivery of secure software. One of the key aspects of the shift-left concept is the incorporation of automation to identify and address software code problems early, such as using continuous integration, continuous delivery, and continuous testing tools. Automation can help reduce manual errors, speed up feedback loops, and increase efficiency and reliability123

The other options are not correct because:

Option A is not correct because large entities with slower release cadences and geographically dispersed systems are more likely to face challenges in adopting the shift-left concept, as they may have more complex and legacy systems, dependencies, and processes that hinder agility and collaboration. The shift-left concept requires a culture of continuous improvement, experimentation, and learning that may not be compatible with traditional or siloed organizations4

Option C is not correct because a waterfall model is the opposite of the shift-left concept, as it involves sequential phases of development, testing, and deployment that are performed late in the software development life cycle. A waterfall model does not allow for early detection and correction of defects, feedback, or changes, and can result in higher costs, delays, and risks5

Option D is not correct because maturity of start-up entities with high-iteration to low-volume code commits is not a sign of the shift-left concept, but rather a sign of the agile or lean software development methodologies. These methodologies focus on delivering value to customers by delivering working software in short iterations or sprints, with frequent feedback and adaptation. While these methodologies can support the shift-left concept by enabling faster testing and delivery cycles, they are not equivalent or synonymous with it6

The primary purpose of the Open Certification Framework (OCF) for the CSA STAR program is to provide global, accredited, and trusted certification of the cloud service provider. According to the CSA website1, 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 framework. The OCF aims to address the gaps within the IT ecosystem that are inhibiting market adoption of secure and reliable cloud services. The OCF also integrates with popular third-party assessment and attestation statements developed within the public accounting community to avoid duplication of effort and cost. The OCF manages the foundation that runs and monitors the CSA STAR Certification program, which is an assurance framework that enables cloud service providers to embed cloud-specific security controls. The STAR Certification program has three levels of assurance, each based on a different type of audit or assessment: Level 1: Self-Assessment, Level 2: Third-Party Audit, and Level 3: Continuous Auditing. The OCF also oversees the CSA STAR Registry, which is a publicly accessible repository that documents the security controls provided by various cloud computing offerings2. The OCF helps consumers to evaluate and compare their providers’ resilience, data protection, privacy capabilities, and service portability. It also helps providers to demonstrate their compliance with industry standards and best practices.

According to the definition of audit scope, it is the extent and boundaries of an audit, which include the audit objectives, the activities and documents covered, the time period and locations audited, and the related activities not audited1 Audit scope determines how deeply an audit is performed and may vary depending on the type of audit. Audit scope can also mean the examination of a person or the inspection of the books, records, or accounts of a person for tax purposes1

The most important audit scope document when conducting a review of a cloud service provider is the processes and systems to be audited. This document defines the specific areas and aspects of the cloud service provider that will be subject to the audit, such as the cloud service delivery model, the cloud deployment model, the cloud security domains, the cloud service level agreements, the cloud governance framework, etc2 The processes and systems to be audited document also helps to identify the risks, controls, criteria, and objectives of the audit, as well as the roles and responsibilities of the auditors and the auditees3 The processes and systems to be audited document is essential for planning and performing an effective and efficient audit of a cloud service provider.

The other options are not correct because:

Option B is not correct because the updated audit work program is not an audit scope document, but rather an audit planning document. The audit work program is a set of detailed instructions or procedures that guide the auditor in conducting the audit activities4 The audit work program is based on the audit scope, but it does not define it. The audit work program may also change during the course of the audit, depending on the findings and issues encountered by the auditor4

Option C is not correct because the documentation criteria for the audit evidence is not an audit scope document, but rather an audit quality document. The documentation criteria for the audit evidence is a set of standards or guidelines that specify what constitutes sufficient and appropriate evidence to support the auditor’s conclusions and opinions5 The documentation criteria for the audit evidence is derived from the audit scope, but it does not determine it. The documentation criteria for the audit evidence may also vary depending on the nature and source of the evidence collected by the auditor5

Option D is not correct because the testing procedure to be performed is not an audit scope document, but rather an audit execution document. The testing procedure to be performed is a set of steps or actions that describe how to test or verify a specific control or process within the cloud service provider6 The testing procedure to be performed is aligned with the audit scope, but it does not establish it. The testing procedure to be performed may also differ depending on the type and level of testing required by the auditor6
