IIA Updated IIA-CIA-Part3 Exam Questions and Answers by herbert

Comprehensive and Detailed In-Depth Explanation:

A decentralized organizational structure distributes decision-making authority across multiple levels. This requires a strong organizational culture to guide decision-making in the absence of centralized control.

Option B (Clear expectations) – While true, this applies to both centralized and decentralized structures.

Option C (Electronic monitoring) – More common in centralized control environments.

Option D (Defined code of behavior) – Found in all organizations, not unique to decentralization.

Since decentralized organizations rely more on cultural alignment, Option A is correct.

A data dictionary describes the content, meaning, structure, format, relationships, and attributes of data stored in a database. It defines items such as field names, data types, valid values, table relationships, and business definitions. This helps ensure consistency, data quality, system understanding, and proper use of information. System tables and program files are technical database components, but they are not the core description of a data dictionary. Users, permissions, and groups are access-control objects, not the primary purpose of a data dictionary. Backup and encryption keys are security and recovery elements. Internal auditors may use a data dictionary to understand data sources, validate analytics fields, and assess data governance. Therefore, Option B is correct.

Access control is about ensuring that only authorized individuals can access specific data, based on their role and necessity. The Principle of Least Privilege (PoLP) dictates that users should only have access to the data they need for their job.

Minimizes Unauthorized Access Risks – Prevents employees from accessing sensitive data unnecessarily.

Supports Segregation of Duties (SoD) – Critical in preventing fraud and security breaches.

Enhances Compliance – Meets regulatory requirements like GDPR, PCI-DSS, and SOX, which demand strict access controls.

Strengthens System Security – Reduces potential damage from malware, insider threats, or data breaches.

A. Install and update anti-virus software – Important for cybersecurity but does not directly control user access.

B. Implement data encryption techniques – Protects stored or transmitted data but does not define access rights.

D. Upgrade firewall configuration – Controls network traffic, not user-specific access within an automated system.

IIA’s GTAG on Access Management and Controls – Recommends setting data access based on user needs to prevent fraud and misuse.

COBIT 2019 (Governance and Management of Enterprise IT) – Advocates for role-based access controls.

ISO 27001 Annex A.9 (Access Control) – Stresses the importance of restricting access based on business requirements.

Why Setting Data Availability by User Need is the Best Strategy?Why Not the Other Options?IIA References:✅ Final Answer: C. Set data availability by user need.

Physical and environmental controls protect IT assets from physical damage, unauthorized physical access, environmental hazards, and operational disruption. Fire detection and suppression, restricted access to tangible IT resources, and disaster recovery planning are relevant to this review. However, ensuring that a developer has access to both systems and operations is inappropriate because it violates segregation of duties. Developers should generally not have unrestricted operational access because they could introduce unauthorized changes, bypass testing, or manipulate production systems. Internal audit should identify excessive access as a control weakness, not a required control activity. Physical and environmental control reviews should include access badges, visitor logs, server room controls, power supply, fire protection, humidity control, and disaster recovery readiness. Therefore, Option D should not be part of the review.
