IIA-CIA-Part3 IIA Business Knowledge for Internal Auditing Free Practice Exam Questions (2025 Updated)

Definition of Rooting:

Rooting (on Android) or Jailbreaking (on iOS) is the process of bypassing manufacturer and administrative security controls on a smart device.

This allows users to gain full control (root access) over the operating system, which can override security restrictions and allow installation of unauthorized applications.

How Rooting Increases Data Security Risks:

Bypassing Security Measures: Rooting removes built-in security protections, making the device more vulnerable to malware, unauthorized access, and data breaches.

Exposure to Malicious Apps: Rooted devices can install third-party applications that are not vetted by official app stores, increasing the risk of data theft, spyware, and ransomware attacks.

Circumventing Enterprise Security Policies: Many organizations use Mobile Device Management (MDM) to enforce security policies, but rooted devices can bypass these controls, exposing corporate data to cyber threats.

Increased Risk of Privilege Escalation Attacks: Attackers can exploit root access to take full control of the device, leading to unauthorized access to sensitive information.

IIA’s Perspective on Cybersecurity Risks:

IIA Standard 2110 – Governance emphasizes the importance of protecting sensitive data and ensuring compliance with IT security policies.

IIA’s GTAG (Global Technology Audit Guide) on Information Security warns against the dangers of rooted or jailbroken devices, as they compromise cybersecurity defenses.

NIST Cybersecurity Framework and ISO 27001 Information Security Standards identify unauthorized modifications to devices as a critical security risk.

Eliminating Incorrect Options:

B. Eavesdropping: This refers to intercepting communications (e.g., listening in on phone calls or network traffic) but does not involve circumventing administrative restrictions.

C. Man-in-the-Middle (MITM) Attack: This is an attack where an attacker intercepts and alters communication between two parties but does not involve rooting a device.

D. Session Hijacking: This attack involves stealing session tokens to impersonate a user but is unrelated to bypassing security controls on devices.

A sound network configuration practice should focus on enhancing security, preventing unauthorized access, and ensuring data integrity. The validation of intrusion prevention controls ensures that the network security measures function as intended and effectively protect data from threats.

(A) Change management practices to ensure operating system patch documentation is retained.

Incorrect: While maintaining patch documentation is important, change management alone does not directly enhance network security.

(B) User role requirements are documented in accordance with appropriate application-level control needs.

Incorrect: This practice improves access control and governance, but it is not a direct network security configuration practice.

(C) Validation of intrusion prevention controls is performed to ensure intended functionality and data integrity. (Correct Answer)

Intrusion Prevention Systems (IPS) help detect and prevent malicious activities in real time.

Ensuring proper validation enhances security and prevents data corruption.

IIA GTAG 15 – Information Security Governance recommends continuous monitoring and validation of security controls.

(D) Interfaces reinforce segregation of duties between operations administration and database development.

Incorrect: Segregation of duties is a good governance practice, but it does not directly relate to network security configuration.

IIA GTAG 15 – Information Security Governance: Recommends validating security controls, including intrusion prevention systems.

IIA Standard 2120 – Risk Management: Encourages proactive security controls to prevent cyber threats.

Analysis of Each Option:IIA References Supporting the Answer:Thus, the correct answer is (C) Validation of intrusion prevention controls, as it directly enhances information security by ensuring real-time threat detection and data integrity.

The Just-in-Time (JIT) method is a managerial accounting and inventory management strategy that focuses on reducing or eliminating excess inventory by receiving goods only as needed.

(A) Theory of constraints.

Incorrect: The theory of constraints focuses on identifying and managing bottlenecks in production, not reducing inventory levels.

(B) Just-in-time method. (Correct Answer)

JIT aims to reduce waste, lower storage costs, and improve efficiency by ensuring that materials and products arrive only when needed.

IIA GTAG 3 – Continuous Auditing suggests monitoring inventory controls to align with JIT principles.

(C) Activity-based costing.

Incorrect: Activity-based costing allocates costs to activities based on usage, not inventory reduction.

(D) Break-even analysis.

Incorrect: Break-even analysis calculates the level of sales needed to cover costs but does not focus on inventory management.

IIA Standard 2120 – Risk Management: Encourages auditors to assess cost-management strategies like JIT.

IIA GTAG 3 – Continuous Auditing: Supports real-time monitoring of inventory to minimize excess stock.

Analysis of Each Option:IIA References Supporting the Answer:Thus, the correct answer is (B) Just-in-Time (JIT) method, as it focuses on achieving low or no inventory to optimize efficiency and reduce costs.
