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

Understanding Copyright Issues and Smart Devices:

Copyright laws protect software, firmware, and intellectual property embedded in smart devices.

Jailbreaking refers to modifying a device’s software to remove manufacturer-imposed restrictions, often to install unauthorized third-party apps.

This violates software licensing agreements and may infringe on copyright protections under laws like the Digital Millennium Copyright Act (DMCA).

Why Option B (Jailbreaking) Is Correct?

Jailbreaking allows users to bypass manufacturer restrictions, potentially leading to unauthorized software distribution and copyright violations.

Manufacturers implement Digital Rights Management (DRM) to protect copyrighted firmware and software, which jailbreaking circumvents.

IIA Standard 2110 – Governance includes evaluating intellectual property risks and compliance in IT audits.

Why Other Options Are Incorrect?

Option A (Session hijacking):

This is a cybersecurity attack where a hacker takes control of a user session. It does not impact copyright laws.

Option C (Eavesdropping):

Eavesdropping refers to unauthorized network surveillance, which is a privacy issue, not a copyright issue.

Option D (Authentication):

Authentication is a security mechanism to verify user identity and has no direct relation to copyright concerns.

Jailbreaking bypasses copyright protections and violates software licensing agreements, making it the best answer.

IIA Standard 2110 emphasizes the importance of IT governance and compliance with intellectual property laws.

Understanding the BCG Matrix and Investment Classifications:

The Boston Consulting Group (BCG) Matrix classifies business investments into four categories:

Stars: High growth, high market share.

Cash Cows: Low growth, high market share.

Question Marks: High growth, low market share.

Dogs: Low growth, low market share.

Why the Investment is a Cash Cow:

The organization operates in a mature, slow-growth industry but has a dominant market position and generates consistent positive financial income.

This aligns with the definition of a Cash Cow, as it represents a stable and profitable business with low reinvestment needs.

Investors typically use Cash Cows to fund other investments, as they generate steady cash flow with minimal risk.

Why Other Options Are Incorrect:

A. A star:

A Star requires high growth and high market share, but the organization operates in a slow-growth industry, disqualifying it from this category.

C. A question mark:

A Question Mark is in a high-growth industry but lacks market dominance. Since this company is already dominant, it does not fit this category.

D. A dog:

A Dog has low growth and low market share, meaning it does not generate strong financial returns. The company described produces positive income, ruling out this category.

IIA’s Perspective on Business Strategy and Portfolio Management:

IIA Standard 2120 – Risk Management states that internal auditors must assess the strategic positioning of business investments.

COSO ERM Framework supports the use of strategic models like the BCG Matrix to evaluate investment performance and risk exposure.

IIA References:

IIA Standard 2120 – Risk Management and Strategic Planning

COSO Enterprise Risk Management (ERM) Framework

Boston Consulting Group (BCG) Matrix in Investment Analysis

Thus, the correct and verified answer is B. A cash cow.

Understanding Organizational Structures:

Organizations structure their workforce based on functions, products, or a combination of both.

A matrix organization combines functional and project-based structures, where employees report to both a functional manager and a project manager.

Why Option C (Matrix Organization) Is Correct?

The software development firm uses employees from multiple departments who report to a single project manager, which is a defining characteristic of a matrix structure.

Employees maintain their departmental roles while contributing to project-based work.

IIA Standard 2110 – Governance supports evaluating flexible organizational structures like matrix organizations to ensure accountability and risk management.

Why Other Options Are Incorrect?

Option A (Functional departmentalization):

In functional structures, employees report to one department head, not a project manager.

Option B (Product departmentalization):

In product-based structures, employees are grouped based on specific product lines, not cross-functional projects.

Option D (Divisional organization):

A divisional structure separates business units based on markets, regions, or customer segments, not cross-functional teams.

A matrix organization allows employees to work across departments under a project manager, making option C the best choice.

IIA Standard 2110 supports assessing governance structures that involve cross-functional teams.

Understanding Job Enrichment:

Job enrichment is a job design technique that increases motivation by adding meaningful responsibilities, autonomy, and recognition to a job.

It aligns with Herzberg’s Two-Factor Theory, which suggests that responsibility and recognition are key motivators.

How Job Enrichment Increases Employee Motivation:

Increases Autonomy: Employees are given more decision-making power, leading to a stronger sense of ownership.

Provides Recognition: Workers receive direct feedback and acknowledgment for their contributions.

Encourages Skill Development: Employees handle more complex tasks, improving job satisfaction and career growth opportunities.

Why Other Options Are Incorrect:

A. Job complicating – Incorrect, as this is not a recognized job design technique; increasing job difficulty does not improve motivation.

B. Job rotation – Incorrect, as job rotation involves shifting employees between different tasks to reduce monotony, but it does not necessarily increase job responsibility or recognition.

D. Job enlargement – Incorrect, as job enlargement adds more tasks at the same skill level, increasing workload without necessarily improving responsibility or recognition.

IIA’s Perspective on Employee Motivation and Organizational Success:

IIA Standard 2120 – Risk Management states that internal auditors should evaluate employee engagement strategies, including job design techniques.

COSO ERM Framework emphasizes that motivated employees contribute to operational efficiency and organizational success.

IIA References:

IIA Standard 2120 – Risk Management & Employee Motivation

Herzberg’s Two-Factor Theory – Motivation through Responsibility and Recognition

COSO ERM – Employee Engagement and Organizational Performance

Thus, the correct and verified answer is C. Job enrichment.

When evaluating a special order, the manufacturer must determine if accepting it will be profitable without disrupting normal operations. The key consideration is whether the company has spare production capacity to handle the order without increasing fixed costs.

Correct Answer (B - The Manufacturer Can Fulfill the Order Without Expanding Production Facilities)

Fixed costs ($3 per unit) are already incurred and will not change if the order is accepted.

The special price ($7 per unit) covers the variable costs ($5 per unit), contributing $2 per unit to profit.

If the manufacturer has excess production capacity, the order is profitable.

The IIA Practice Guide: Auditing Financial Performance emphasizes that special order decisions should be based on incremental cost analysis, ensuring no need for capacity expansion.

Why Other Options Are Incorrect:

Option A (Fixed and Variable Manufacturing Costs Are Less Than the Special Offer Selling Price):

Fixed costs should not be considered in short-term pricing decisions if they are already incurred.

Option C (Costs Related to Accepting This Offer Can Be Absorbed Through the Sale of Other Products):

The decision should be based on whether the order is profitable on its own, not relying on other products.

Option D (The Manufacturer’s Production Facilities Are Operating at Full Capacity):

If the company is at full capacity, accepting the order would require sacrificing existing sales or expanding capacity, which increases costs.

IIA Practice Guide: Auditing Financial Performance – Discusses cost analysis for special pricing decisions.

IIA GTAG 13: Business Performance – Covers incremental cost and profitability analysis in pricing decisions.

Step-by-Step Explanation:IIA References for Validation:Thus, B is the correct answer because accepting the order is only profitable if the manufacturer has excess capacity.

Absorption costing is a costing method that allocates all manufacturing costs (both variable and fixed) to the cost of a product. In this method, fixed manufacturing overhead costs are treated as indirect product costs because they are not directly traceable to a single unit of production but are still part of the total cost of producing goods.

Let’s analyze each option:

Option A: Direct, product costs.

Incorrect. Direct costs are costs that can be traced directly to a specific product, such as direct materials and direct labor. Fixed manufacturing overhead is not a direct cost because it is spread across all units produced.

Option B: Indirect product costs.

Correct. Fixed manufacturing overhead costs (such as rent, depreciation, and utilities for the production facility) are indirect costs because they support the entire production process rather than a specific product. However, under absorption costing, they are still treated as product costs and allocated to inventory.

IIA Reference: The IIA’s guidance on cost allocation states that absorption costing assigns all manufacturing costs (including fixed overhead) to products. (IIA Practice Guide: Cost and Profitability Analysis)

Option C: Direct period costs.

Incorrect. Period costs are expensed in the period they occur, while absorption costing treats fixed manufacturing overhead as part of inventory (product cost) until sold.

Option D: Indirect period costs.

Incorrect. Fixed manufacturing overhead is not expensed immediately as a period cost under absorption costing; it is capitalized into inventory and expensed as Cost of Goods Sold (COGS) when the product is sold.

Thus, the verified answer is B. Indirect product costs.

An Intranet is a private network that is accessible only to an organization’s personnel. It is used for internal communication, data sharing, and collaboration while ensuring security and restricted access.

Let’s analyze each option:

Option A: An extranet

Incorrect. An extranet extends an organization’s internal network to external parties such as vendors, suppliers, or business partners. Since the organization wants to allow access only to its personnel, an extranet is not the right choice.

Option B: A local area network (LAN)

Incorrect. While a LAN is a network within a limited geographic area (such as an office), it does not necessarily restrict access only to personnel. Additionally, an intranet operates over a LAN but includes access controls and authentication mechanisms.

Option C: An Intranet

Correct. An intranet is specifically designed for internal use, allowing employees to securely share documents, collaborate, and access internal resources. Organizations can implement access control mechanisms to restrict access to authorized personnel only.

IIA Reference: Internal auditors assess IT security to ensure that internal networks (such as intranets) have appropriate access restrictions to protect sensitive data. (IIA GTAG: Auditing IT Networks)

Option D: The internet

Incorrect. The internet is a public network that does not restrict access. Using the internet for internal communication would expose sensitive data to external threats.

Thus, the verified answer is C. An Intranet.

A disaster recovery plan (DRP) ensures that an organization can restore operations after a major IT system failure. The level of readiness depends on the type of recovery site used:

Correct Answer (A - A Warm Recovery Plan)

A warm site is a partially configured recovery site with some hardware and network infrastructure in place.

In the event of a disaster, some configuration and data restoration are required before full operation can resume.

This solution balances cost and recovery speed, making it ideal for moderate-risk scenarios.

The IIA GTAG 10: Business Continuity Management discusses warm sites as an effective disaster recovery solution.

Why Other Options Are Incorrect:

Option B (A Cold Recovery Plan):

A cold site has minimal infrastructure and requires significant time for setup and data restoration.

This is not ideal for organizations needing faster recovery.

Option C (A Hot Recovery Plan):

A hot site is a fully operational backup system that allows instant recovery, but it is very costly.

The scenario mentions "some configuration and data restoration", which suggests a warm site, not a hot site.

Option D (A Manual Work Processes Plan):

A manual plan involves non-IT solutions, which would not address IT system restoration.

IIA GTAG 10: Business Continuity Management – Describes warm, cold, and hot sites for disaster recovery.

IIA Practice Guide: Auditing Business Continuity Plans – Recommends warm recovery sites for balancing cost and recovery time.

Step-by-Step Explanation:IIA References for Validation:Thus, A is the correct answer because a warm recovery plan allows partial system readiness with minimal downtime.

Understanding Data Analysis in Internal Auditing

Data analytics enhances audit testing by identifying patterns, anomalies, and high-risk transactions within large datasets.

Advanced analytics tools (e.g., AI, machine learning, continuous auditing) help auditors pinpoint areas of fraud, compliance violations, or operational inefficiencies.

Why Option B is Correct?

Data analysis improves risk assessment by allowing auditors to focus on high-risk areas, such as fraudulent transactions or control weaknesses.

IIA Standard 1220 – Due Professional Care requires auditors to use technology to improve audit effectiveness, including identifying risks.

IIA GTAG (Global Technology Audit Guide) 16 – Data Analytics supports using analytics to enhance risk-based auditing.

Why Other Options Are Incorrect?

Option A (Improves effectiveness of spot check testing techniques):

Data analysis enables continuous and full-population testing, rather than just improving spot checks.

Option C (Reduces the overall scope of the audit engagement):

Analytics refines audit focus but does not necessarily reduce the scope; it may expand testing capabilities.

Option D (Increases the auditor’s objectivity):

Objectivity is an ethical requirement rather than a direct effect of data analysis.

Data analytics enhances internal audit testing by providing deeper insights into high-risk areas.

IIA Standard 1220 and GTAG 16 emphasize data analytics in risk-based auditing.

Final Justification:IIA References:

IPPF Standard 1220 – Due Professional Care

IIA GTAG 16 – Data Analytics in Auditing

COSO Framework – Data-Driven Risk Management

A declining inventory turnover means that inventory is sitting longer before being sold, while an increasing gross margin rate suggests the company is making higher profits on each sale. This combination is often a sign of inventory overstatement, possibly due to accounting errors or fraud.

Correct Answer (D - The Organization’s Inventory is Overstated)

Inventory turnover ratio = Cost of Goods Sold (COGS) / Average Inventory. A declining inventory turnover indicates higher inventory levels relative to sales.

Gross margin rate = (Revenue - COGS) / Revenue. An increasing gross margin means either higher selling prices or lower COGS.

Overstating inventory artificially reduces COGS, making gross margin appear higher.

The IIA’s GTAG 8: Audit of Inventory Management explains that inflated inventory levels can distort financial reporting and lead to misinterpretations of business performance.

Why Other Options Are Incorrect:

Option A (Operating expenses are increasing):

An increase in operating expenses would not directly explain declining inventory turnover or increasing gross margin.

Gross margin focuses on revenue and COGS, not operating expenses.

Option B (Just-in-Time Inventory):

A just-in-time (JIT) system reduces inventory levels, leading to higher inventory turnover, which contradicts the scenario.

Option C (Inventory Theft):

If theft were occurring, inventory levels would decrease, leading to higher turnover, not declining turnover.

GTAG 8: Audit of Inventory Management – Discusses inventory valuation risks, including overstatement and its impact on financial ratios.

IIA Practice Guide: Assessing Inventory Risks – Covers fraud risks related to inventory manipulation.

Step-by-Step Explanation:IIA References for Validation:Thus, the best explanation for a declining inventory turnover with an increasing gross margin rate is inventory overstatement (D).

The most effective way to prevent the unauthorized disclosure of confidential information is to limit access based on employee roles and duties. This follows the principle of least privilege (PoLP), ensuring that employees only access the data necessary for their job functions.

(A) Nondisclosure agreements between the firm and its employees. ❌

Incorrect. While NDAs help deter leaks, they do not prevent unauthorized access to information. An employee who signs an NDA can still access and leak data.

(B) Logs of user activity within the information system. ❌

Incorrect. Activity logs help detect and investigate breaches but do not actively prevent unauthorized disclosure.

(C) Two-factor authentication for access into the information system. ❌

Incorrect. While two-factor authentication enhances system security, it does not prevent employees with authorized access from leaking confidential data.

(D) Limited access to information, based on employee duties. ✅

Correct. Role-based access control (RBAC) ensures that employees only access the information necessary for their job responsibilities, reducing the risk of leaks.

IIA GTAG "Identity and Access Management" highlights restricted access as the most effective control for preventing unauthorized disclosure of confidential data.

IIA GTAG – "Identity and Access Management"

IIA Standard 2120 – Risk Management (Data Protection Controls)

COBIT Framework – Information Security and Access Control

Analysis of Answer Choices:IIA References:Thus, the correct answer is D (Limited access to information, based on employee duties), as restricting access is the most effective preventive control against data disclosure.

Herzberg’s Two-Factor Theory of Motivation identifies two categories of workplace factors:

Hygiene Factors – Prevent dissatisfaction but do not create motivation (e.g., salary, job security, work conditions).

Motivational Factors – Lead to job satisfaction and motivation (e.g., achievement, responsibility, advancement, recognition).

(A) Salary and status. ❌ Incorrect.

Salary is a hygiene factor, meaning it prevents dissatisfaction but does not directly drive job satisfaction.

Status is also not a strong motivator under Herzberg’s theory.

(B) Responsibility and advancement. ✅ Correct.

These are motivational factors in Herzberg’s theory.

Employees feel satisfied when they have responsibility, career growth, and promotion opportunities.

IIA GTAG "Auditing Human Resource Management" highlights career development as a key driver of employee motivation and retention.

(C) Work conditions and security. ❌ Incorrect.

These are hygiene factors, which help avoid dissatisfaction but do not actively motivate employees.

(D) Peer relationships and personal life. ❌ Incorrect.

Good relationships with coworkers help, but they are not primary motivators under Herzberg’s theory.

IIA GTAG – "Auditing Human Resource Management"

IIA Standard 2110 – Governance (Employee Motivation & Engagement)

Herzberg’s Two-Factor Theory of Motivation (Workplace Psychology Research)

Analysis of Answer Choices:IIA References:Thus, the correct answer is B, as responsibility and advancement are the key motivational factors leading to employee satisfaction.

In a vertically centralized organization, decision-making authority is concentrated at the top levels of management. As a company rapidly expands, maintaining tight control by a small management team can lead to inefficiencies, delays, and suboptimal decision-making due to limited input from operational and frontline staff.

Let’s analyze each option:

Option A: Lack of coordination among different business units

Incorrect. While coordination challenges can exist in a large, decentralized organization, a tightly controlled, centralized structure typically ensures strong coordination but at the cost of slower decision-making.

Option B: Operational decisions are inconsistent with organizational goals

Incorrect. In a centralized structure, top management closely controls decision-making, making goal misalignment less likely.

Option C: Suboptimal decision making

Correct.

Decentralized decision-making allows managers closer to operations to make informed, timely decisions.

A small centralized team may lack specialized knowledge about different departments, leading to inefficient or outdated decisions.

As the company expands, delays in decision-making and lack of responsiveness to market conditions increase risk exposure.

IIA Reference: Internal auditors assess organizational structures to identify risks associated with inefficient decision-making and control bottlenecks. (IIA Standard 2110: Governance)

Option D: Duplication of business activities

Incorrect. Duplication of activities is more common in decentralized structures, where different departments operate independently. A tightly controlled, centralized structure reduces redundancy but at the cost of decision-making efficiency.

Thus, the verified answer is C. Suboptimal decision making.

Understanding the Accounting for Office Supplies:

The organization maintains an account for office supplies on hand, which represents unused office supplies at any given time.

The expense recorded during the year represents the cost of office supplies purchased.

At year-end, the adjusting entry is made to reflect the actual amount of supplies on hand and adjust the supplies expense accordingly.

Formula to Determine the Supplies Used:

Supplies Used=Beginning Balance+Purchases−Ending Balance\text{Supplies Used} = \text{Beginning Balance} + \text{Purchases} - \text{Ending Balance}Supplies Used=Beginning Balance+Purchases−Ending Balance

Plugging in the given values:

Supplies Used=9,000+45,000−11,500=42,500\text{Supplies Used} = 9,000 + 45,000 - 11,500 = 42,500Supplies Used=9,000+45,000−11,500=42,500

This amount ($42,500) represents the actual office supplies used and should be recorded as an expense.

The adjusting entry would include:

A debit to Office Supplies on Hand for $42,500

A credit to Office Supplies Expense for $42,500

Why Other Options Are Incorrect:

A. A debit to office supplies on hand for $2,500 – Incorrect, as this figure does not represent supplies used or purchased.

B. A debit to office supplies on hand for $11,500 – Incorrect, as this is the ending balance and not the adjustment amount.

C. A debit to office supplies on hand for $20,500 – Incorrect, as this does not align with the formula for calculating used supplies.

IIA’s Perspective on Financial Reporting and Adjusting Entries:

IIA Standard 1220 – Due Professional Care emphasizes accurate financial reporting and proper adjustments for year-end entries.

GAAP Accounting Principles require accrual-based adjustments to ensure that expenses are recognized in the period they are incurred.

COSO Internal Control Framework supports proper inventory and expense adjustments to avoid misstated financials.

IIA References:

IIA Standard 1220 – Due Professional Care (Financial Reporting Accuracy)

GAAP Accounting Standards – Adjusting Entries for Supplies and Inventory

COSO Internal Control – Accurate Expense Recognition

Thus, the correct and verified answer is D. A debit to office supplies on hand for $42,500.

Authorization controls ensure that users have appropriate access levels based on their roles and responsibilities. The primary concern arises when all users have uniform access, as it violates the principle of least privilege (PoLP) and increases the risk of unauthorized access and data breaches.

(A) Users can only see certain screens in the system.

Incorrect. This is a good security practice, as it limits user access based on job roles, preventing unauthorized access to sensitive information.

(B) Users are making frequent password change requests.

Incorrect. Frequent password resets might indicate poor password management but are not directly related to authorization controls.

(C) Users input incorrect passwords and get denied system access.

Incorrect. This indicates authentication issues, not an authorization control concern. If users are denied access due to incorrect passwords, the system’s authentication mechanisms are working correctly.

(D) Users are all permitted uniform access to the system. ✅

Correct. Authorization should be role-based, meaning different users should have different levels of access depending on their responsibilities. Uniform access violates security best practices and increases the risk of fraud, data misuse, and compliance violations.

IIA GTAG "Identity and Access Management" emphasizes that authorization controls should be based on job functions to prevent unnecessary exposure to sensitive data.

IIA Standard 2120 – Risk Management highlights the importance of access control policies to mitigate cybersecurity risks.

IIA GTAG – "Identity and Access Management"

IIA Standard 2120 – Risk Management

COBIT Framework – Access Control and Identity Management

Analysis of Answer Choices:IIA References:Thus, the correct answer is D, as uniform access across all users is a major security concern in authorization control.

The internal rate of return (IRR) is a measure used to evaluate the profitability of an investment. The project is considered acceptable if its IRR is greater than or equal to the required rate of return (RRR), which is the minimum return an organization expects from an investment.

Correct Answer (C - Compare to the Required Rate of Return)

The required rate of return (RRR) represents the minimum acceptable return for the project.

If IRR ≥ RRR, the project is acceptable. If IRR < RRR, the project is rejected.

The IIA Practice Guide: Auditing Capital Investments suggests comparing IRR to the RRR to ensure financial feasibility.

Why Other Options Are Incorrect:

Option A (Compare to the annual cost of capital):

The cost of capital (WACC - Weighted Average Cost of Capital) is an important factor, but RRR is the direct benchmark for IRR comparison.

Option B (Compare to the annual interest rate):

Interest rates do not determine project feasibility—they only affect financing costs.

Option D (Compare to the net present value - NPV):

NPV and IRR are related, but they serve different purposes.

IRR is compared against RRR, while NPV measures absolute profitability in dollar terms.

IIA Practice Guide: Auditing Capital Investments – Discusses IRR, RRR, and investment decision-making.

IIA GTAG 3: Business Case Development – Explains how financial metrics like IRR and RRR are used in decision-making.

Step-by-Step Explanation:IIA References for Validation:Thus, C is the correct answer because IRR should be compared to the required rate of return to determine project acceptability.

Understanding E-Commerce Systems and Their Financial Impact

E-commerce systems, including electronic data interchange (EDI) and electronic funds transfer (EFT), streamline procurement and payment processes.

The main financial effect of implementing such a system is the acceleration of accounts payable transactions.

This is because automated purchasing systems allow businesses to place orders faster and in larger volumes, leading to an increase in outstanding liabilities (accounts payable) before payments are settled.

Why Option D is Correct?

Higher accounts payable occur because:

EDI automates order placement, leading to more frequent and possibly larger purchases before payments are processed.

EFT may improve payment processing speed, but it does not eliminate outstanding payables immediately.

Suppliers may extend credit terms, increasing the organization's short-term liabilities under accounts payable.

IIA Standard 2110 – Governance requires internal auditors to evaluate how technology changes impact financial controls, including accounts payable management.

COBIT 5 Framework – AP Processes emphasizes that auditors should monitor financial system integration risks, including liabilities like accounts payable.

Why Other Options Are Incorrect?

Option A (Higher cash flow and treasury balances):

E-commerce improves transaction efficiency but does not necessarily increase cash flow. It may even reduce available cash due to frequent automated purchases.

Option B (Higher inventory balances):

EDI can reduce inventory levels due to just-in-time (JIT) ordering, rather than increasing them.

Option C (Higher accounts receivable):

Accounts receivable refers to money owed to the organization, but e-commerce impacts payables (money owed by the organization) more directly.

E-commerce accelerates order processing and supplier payments, increasing accounts payable balances before payment cycles are completed.

IIA Standard 2110 and COBIT 5 stress financial controls, including monitoring accounts payable risks.

Final Justification:IIA References:

Understanding the "Something You Have" Concept:

Access control methods are classified into three main authentication factors:

Something You Know – Passwords, PINs, security questions.

Something You Have – Physical devices like keycards, smart cards, or security tokens.

Something You Are – Biometrics such as fingerprints, retina scans, or voice recognition.

Why a Card-Key Scanner is the Correct Answer:

A card-key scanner verifies access using a physical card, which aligns with the "something you have" authentication factor.

Users must possess the key card to gain entry, making it a classic example of physical token-based security.

Why Other Options Are Incorrect:

A. A retina characteristics reader – Incorrect, as retina scans fall under "something you are" (biometrics), not "something you have".

B. A PIN code reader – Incorrect, as PIN codes are "something you know", not a physical possession.

D. A fingerprint scanner – Incorrect, as fingerprints are biometric ("something you are"), not a physical object.

IIA’s Perspective on Physical Security Controls:

IIA Standard 2110 – Governance emphasizes the importance of using multi-factor authentication to enhance security.

IIA GTAG (Global Technology Audit Guide) on Access Control recommends the use of physical security devices like card-key scanners to prevent unauthorized access.

ISO 27001 Information Security Standard identifies "something you have" authentication methods as critical components of access control.

IIA References:

IIA Standard 2110 – Governance & IT Security

IIA GTAG – Physical Security & Access Controls
