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

Understanding IT Infrastructure Risks and Workstation Security:

Reviewing an organization’s IT infrastructure risks includes assessing the security of workstations (desktops, laptops, and terminals) that connect to the organization's network.

Workstations are vulnerable to physical theft, unauthorized access, and malware attacks, making physical controls a critical security measure.

Why Physical Controls Are the Most Relevant for Workstations:

Physical controls prevent unauthorized physical access, theft, tampering, and damage to workstations.

Examples include:

Locked office spaces or workstation enclosures to restrict access.

Security badges or biometric authentication to prevent unauthorized use.

Cable locks for laptops and desktop computers to deter theft.

Surveillance cameras and security guards to monitor access.

Why Other Options Are Incorrect:

A. Input controls – Incorrect.

Input controls ensure accuracy and completeness of data entry, which applies more to application security, not workstation security.

B. Segregation of duties – Incorrect.

Segregation of duties prevents fraud and conflicts of interest, but it does not directly address workstation security risks.

D. Integrity controls – Incorrect.

Integrity controls ensure data consistency and accuracy in databases and transactions, not workstation security.

IIA’s Perspective on IT Risk and Physical Security Controls:

IIA Standard 2110 – Governance requires organizations to implement physical security measures for IT assets, including workstations.

IIA GTAG (Global Technology Audit Guide) on IT Risks highlights the importance of restricting physical access to IT devices to prevent unauthorized use or data breaches.

ISO 27001 Information Security Standard recommends physical controls to secure IT infrastructure and prevent workstation-related risks.

IIA GTAG – Physical Security of IT Assets

ISO 27001 – Physical Security and IT Risk Management

Thus, the correct and verified answer is C. Physical controls.

Physical controls are security measures that prevent unauthorized physical access to critical assets, such as IT infrastructure, sensitive documents, or restricted areas.

(A) Preventing database administrators from initiating program changes:

This is a logical (IT) control rather than a physical control. Logical controls manage access permissions and prevent unauthorized software changes.

(B) Blocking technicians from getting into the network room (Correct Answer):

This is a physical control because it prevents unauthorized personnel from physically accessing critical IT infrastructure, such as servers and networking devices.

Unauthorized access to a network room could lead to data breaches, hardware manipulation, or cyberattacks.

(C) Restricting system programmers' access to database facilities:

This is an access control measure, which can be either logical (permissions, role-based access) or physical. However, it primarily refers to IT access controls rather than a physical security measure.

(D) Using encryption for data transmitted over the public internet:

This is a technical control, not a physical one. Encryption protects data but does not prevent physical breaches.

IIA GTAG 17: Auditing IT Security – Emphasizes the role of physical security in protecting IT infrastructure.

COBIT Framework – DSS05 (Manage Security Services) – Highlights physical access restrictions as a key security measure.

ISO/IEC 27001: Information Security Management System – Identifies physical security as a fundamental control for IT risk management.

Analysis of Each Option:IIA References:Conclusion:Since physical security controls prevent unauthorized physical access, option (B) is the correct answer.

In the context of big data governance, the responsibilities of various stakeholders are delineated as follows:

A. Management's Responsibilities:

Management holds the primary responsibility for establishing and maintaining effective data governance frameworks. This includes ensuring that information storage systems are appropriately defined and that processes for updating critical data elements are clear and well-documented. Such measures are essential to maintain data integrity, availability, and confidentiality. The Institute of Internal Auditors (IIA) emphasizes that management is accountable for the design and implementation of data governance structures, policies, and procedures. These structures should encompass data storage solutions and the mechanisms for updating and managing critical data elements.

B. External Auditors' Responsibilities:

External auditors are tasked with providing independent assurance on the effectiveness of an organization's financial reporting and related controls. While they may consider the implications of big data on financial reporting, their primary focus is not on the periodic monitoring and maintenance of analytical models. Instead, this responsibility typically falls under management or specialized internal functions. The IIA outlines that external auditors assess the overall control environment but do not directly manage or maintain analytical models.

C. The Board's Responsibilities:

The board of directors provides oversight and strategic direction for the organization's data governance initiatives. However, the implementation of specific controls around data quality dimensions is generally delegated to management. The board ensures that appropriate governance structures are in place and that management is effectively addressing data quality and governance issues. According to the IIA, the board's role is to oversee the data governance framework, ensuring that management has implemented effective controls and processes.

The Institute of Internal Auditors

D. Internal Auditors' Responsibilities:

Internal auditors provide independent assurance on the effectiveness of governance, risk management, and control processes, including those related to data quality and security. While they assess and report on the adequacy of controls over data, the responsibility for ensuring data quality and security rests with management. The IIA states that internal auditors evaluate the effectiveness of data governance practices but do not hold primary responsibility for data quality and security.

The Institute of Internal Auditors

In summary, option A accurately reflects management's responsibility in big data governance, aligning with the IIA's guidelines on data governance roles and responsibilities.

IT General Controls (ITGCs) refer to foundational IT controls that support the reliability and security of information systems across all applications. Systems development controls fall under ITGCs because they ensure that:

IT systems are developed, tested, and implemented securely.

Change management, system testing, and access controls are enforced before deployment.

Ensuring Secure Development Practices:

IIA GTAG 8: Auditing Application Controls states that strong systems development controls prevent unauthorized access and errors in IT systems.

Risk Mitigation in Software Changes:

IIA Standard 2110 – Governance requires IT governance to enforce security policies for system development.

Weak controls increase risks of security vulnerabilities and financial misstatements.

Alignment with COSO & COBIT Frameworks:

COBIT (Control Objectives for Information and Related Technologies) classifies systems development controls as an ITGC domain.

COSO Internal Control – Integrated Framework supports secure system change processes.

A. Error listings (Incorrect)

Reason: Error listings are application controls that detect transaction errors within specific processes. ITGCs support all systems, not just specific applications.

B. Distribution controls (Incorrect)

Reason: Distribution controls deal with physical/logistical distribution of information or resources, not core ITGC functions.

C. Transaction logging (Incorrect)

Reason: While transaction logging is important for data integrity and security, it is an application control, not a general IT control.

IIA GTAG 8: Auditing Application Controls – Defines IT general controls and application-specific controls.

IIA Standard 2110 – Governance – Requires secure IT development and governance structures.

COBIT & COSO Internal Control Frameworks – Classify system development controls as critical ITGCs.

Why is Answer D Correct?Analysis of Incorrect Answers:IIA References:Thus, the correct answer is D. Systems development controls.
