ISO 27001: Auditing IT Governance: ISO 27001 and GDPR Compliance
Under ISO 27001 (The IIA (GIAS) / COSO), auditing IT Governance: ISO 27001 and GDPR Compliance establishes the authoritative rules tested on the IIA CIA. A world-class guide for internal auditors on planning and performing engagements that assess an Information Security Management System (ISMS) using ISO 27001/27002 and evaluate compliance with GDPR, all within the framework of the Global Internal Audit Standards, verified against VoraPrep's IIA CIA blueprint.
ISO 27002 Control Themes

|---|---|---|
| Organizational | 37 | Information security policies, asset management, supplier security, threat intelligence. |
| People | 8 | Security awareness training, screening, remote working policies, disciplinary process. |
| Physical | 14 | Secure areas, physical entry controls, clear desk/screen, equipment maintenance. |
| Technological | 34 | Access control, authentication, encryption, data leakage prevention, network security. |
MediCare Solutions, a healthcare technology firm operating globally, processes vast amounts of sensitive patient health information (PHI) and personally identifiable information (PII). Following a recent expansion into the European Union, MediCare Solutions is now subject to the General Data Protection Regulation (GDPR). The internal audit department is tasked with assessing the company's data privacy compliance and risk posture. During their review, auditors discover that data minimization principles are not consistently applied across all data collection points, and data retention policies are not uniformly enforced, leading to the storage of unnecessary and outdated personal data. In light of the GDPR requirements and IIA Standard 2120.A1, which of the following internal audit recommendations would be most critical for MediCare Solutions to address the identified data privacy risks effectively?
Worked Example: Auditing a Cloud Migration
Scenario: An internal auditor at FinSecure, a financial services firm, is planning an engagement to review the company's recent migration of customer data to a third-party cloud provider, CloudHost Inc. The objective is to provide assurance that the arrangement complies with GDPR and aligns with the company's ISMS. This aligns with the fundamental Purpose of Internal Auditing (GIAS Domain I), which is to enhance and protect organizational value by providing risk-based and objective assurance, advice, and insight.
- Audit Steps: 1. Review the Contract (Organizational Control): The auditor first examines the contract with CloudHost Inc. They verify that it explicitly defines FinSecure as the Data Controller and CloudHost Inc. as the Data Processor. The contract must include specific clauses mandating that CloudHost only process data on FinSecure's instructions. 2. Verify Data Processing (Purpose Limitation): The auditor requests logs and system configurations to confirm that CloudHost is only using the data for the agreed-upon purpose (e.g., storage and backup) and not for its own analytics or marketing, which would violate the purpose limitation principle. 3. Assess Security Controls (Integrity & Confidentiality): The auditor reviews CloudHost's security certifications (e.g., SOC 2 report, their own ISO 27001 certification) and requests evidence of specific technological controls, such as encryption for data at rest and in transit. This links ISO 27002 controls directly to the GDPR security principle. 4. Check Data Retention (Storage Limitation): The auditor tests the system's data retention policies to ensure customer data is being automatically and securely deleted after the period defined in FinSecure's policy, satisfying the storage limitation principle.
- Finding: The auditor discovers the contract lacks a clear data breach notification clause specifying a timeframe for CloudHost to report a breach to FinSecure. This is a critical gap, as GDPR requires controllers to notify authorities within 72 hours. Therefore, the auditor's primary recommendation must be for management to amend the contract to include a specific and timely breach notification clause that aligns with GDPR requirements.
- If you picked a distractor option like 'Accepting CloudHost's ISO 27001 certification as sufficient evidence of GDPR compliance,' you would be making a common error. While ISO 27001 certification is a strong indicator of a mature security posture (addressing the GDPR's 'Integrity and Confidentiality' principle), it is not a substitute for specific legal and contractual compliance. GDPR has explicit requirements, such as breach notification timelines and data subject rights, that are not automatically covered by an ISO certification. The audit must test both technical controls and legal/contractual obligations.
Common IIA CIA Distractors on ISO 27001
- 1Step 1: Identify the Auditor's Role and Objective. First, determine the context. Are you planning an engagement, testing controls, or reporting a finding? This frames the most appropriate action and perspective.
- 2ISO 27001 defines the requirements for a certifiable Information Security Management System (ISMS), using a Plan-Do-Check-Act model.
- 3ISO 27002 provides a detailed catalog of 93 security controls across four themes (Organizational, People, Physical, Technological) to support ISO 27001.
- 4GDPR has seven core principles (remember LAPD SIA) and applies extraterritorially to any organization processing EU residents' data.
- 5Auditors must distinguish between a Data Controller (who determines 'why' and 'how') and a Data Processor (who acts on behalf of the controller).
