ISO 27001: Auditing Cloud Security: Governance, Risk, and the Shared Responsibility Model
Under ISO 27001 (ISACA / NIST / SOC 2), auditing Cloud Security: Governance, Risk, and the Shared Responsibility Model establishes the authoritative rules tested on the ISACA CISA. A world-class guide for IS auditors on evaluating cloud environments. VoraPrep verifies every threshold, worked table, and practice question below against the current ISACA CISA blueprint.
ISO 27001 — Key Statutory Scope & Exam Matrix
| Rule Dimension | Authoritative Standard | Practitioner & Exam Application |
|---|---|---|
| Primary Authority | ISO 27001 | Enforced / tested under ISACA / NIST / SOC 2 |
| Exam Blueprint Area | CISA5 (CISA5-E) | Tested on the ISACA CISA |
| Core Requirement 1 | Shared Responsibility Model | Required rule boundary & scenario application |
| Core Requirement 2 | Cloud Service Models (IaaS, PaaS, SaaS) | Required rule boundary & scenario application |
| Core Requirement 3 | Cloud Governance Frameworks | Required rule boundary & scenario application |
| Core Requirement 4 | Information Asset Security and Control (IAM, Cryptography, Network Security, Cloud Architecture) | Required rule boundary & scenario application |
A healthcare provider has recently deployed a large number of interconnected Internet of Things (IoT) medical devices for patient monitoring. An IS auditor is assessing the associated risks. Which of the following represents the MOST significant risk associated with this new deployment?
Worked Example: Auditing a PaaS Deployment
Scenario: An IS auditor is conducting a post-implementation review of a new customer relationship management (CRM) application deployed on a Platform as a Service (PaaS) platform for FinCorp.
- Numbered Steps of the Audit:
- 1. Identify the Service Model and Responsibilities: The auditor confirms it's a PaaS model. According to the shared responsibility model, FinCorp is responsible for the application code, user access management, and the data. The provider is responsible for the underlying OS, network, and physical infrastructure. The audit scope is therefore focused on FinCorp's responsibilities.
- 2. Review Governance and Vendor Due Diligence: The auditor requests the cloud governance policy and finds that the project team bypassed the formal risk assessment process for the PaaS provider to save time, a violation of policy. This is a governance finding.
- 3. Test Identity and Access Management (IAM) Controls: The auditor requests an export of all IAM role definitions. They discover that the 'developer' role has been granted full administrative privileges in the production environment, including the ability to read and export all customer data. This is a severe violation of segregation of duties and the principle of least privilege.
Common ISACA CISA Distractors on ISO 27001
- 1Think of cloud services like ordering a pizza:
- 2On-Premises (Making pizza at home): You manage everything: the kitchen, oven, ingredients, cooking, and serving.
- 3IaaS (Take and Bake): The pizza place provides the dough, sauce, and cheese (infrastructure). You manage the baking, serving, and toppings (OS, applications, data).
- 4PaaS (Pizza Delivery): The pizza place handles everything up to cooking the pizza (platform). You just provide the table and drinks (your application and data).
- 5SaaS (Dining Out): You just show up and eat. The restaurant handles everything (the software). You are only responsible for who you invite to dinner (user access).
