ISACA Certified Information Systems Auditor (CISA) ExamDomain 1: Information System Auditing ProcessEasy
An IS auditor is preparing to conduct an audit of an organization's new cloud-based customer relationship management (CRM) system. Management has expressed concerns about the security of customer data hosted by the third-party cloud provider. Which of the following is the MOST important step for the IS auditor to perform first?
- APerform vulnerability scans on the organization's network perimeter.
- BObtain and review the cloud provider's Service Organization Control (SOC) 2 report.
- CInterview key CRM system users to understand their data access requirements.
- DDevelop a detailed test plan for the CRM system's application controls.
Show answer & explanationAnswer & explanation
Correct answer: B. Obtain and review the cloud provider's Service Organization Control (SOC) 2 report.
Before developing detailed test plans or interviewing users, the IS auditor must first understand the controls in place at the third-party cloud provider. A SOC 2 report provides assurance regarding these controls, which is crucial given management's security concerns about customer data.
Why the other options are wrong
- A. Performing vulnerability scans on the organization's perimeter is relevant for the organization's own infrastructure, but not for the cloud provider's hosted environment.
- C. Interviewing users is a valuable step for understanding business processes and access needs, but it doesn't address the primary concern about the cloud provider's security.
- D. Developing a detailed test plan for application controls is important but should follow an understanding of the third-party's controls.
Third-Party Assurance (SOC Reports)
Service Organization Control (SOC) reports provide an independent auditor's opinion on controls at a service organization relevant to user entities' internal control over financial reporting (SOC 1) or security, availability, processing integrity, confidentiality, or privacy (SOC 2).
- SOC 2 reports specifically address security, availability, processing integrity, confidentiality, and privacy.
- Essential for auditing cloud providers or any third-party handling sensitive data.
- Helps IS auditors assess control effectiveness without directly auditing the third party.
