IIA-CIA-Part3 Exam Dumps : Business Knowledge for Internal Auditing

Fraud in time-tracking systems—such as "buddy punching" (where one employee clocks in/out for another)—is a common payroll fraud scheme. The most effective method to prevent this is biometric authentication, which ensures that only the actual employee can clock in or out.

(A) Face or finger recognition equipment. ✅

Correct. Biometric authentication (such as fingerprint or facial recognition) is the most effective solution because it uniquely identifies each individual, making it impossible for an employee to clock in on behalf of a colleague.

IIA GTAG "Managing and Auditing IT Vulnerabilities" recommends biometric authentication as a strong fraud prevention measure.

IIA Practice Guide "Fraud Prevention and Detection in an Automated Environment" highlights the use of biometrics for enhancing security in access control systems.

(B) Radio-frequency identification (RFID) chips to authenticate employees with cards.

Incorrect. RFID cards can be shared between employees, allowing fraud to continue. They are useful for access control but do not verify the identity of the person using the card.

(C) A requirement to clock in and clock out with a unique personal identification number (PIN).

Incorrect. PINs can be shared or stolen, making them ineffective in preventing buddy punching.

(D) A combination of a smart card and a password to clock in and clock out.

Incorrect. Like RFID and PIN systems, smart cards and passwords can be shared, making them ineffective against fraudulent time-tracking practices.

Analysis of Answer Choices:IIA References:Thus, the correct answer is A, as biometric authentication directly verifies the employee’s identity, preventing time-tracking fraud.

Definition of Flexible Budgets:

Flexible budgeting allows organizations to adjust budgeted expenses based on actual performance levels.

Unlike static budgets, flexible budgets provide different financial projections for varying levels of activity.

Why Flexible Budgets are Useful:

They adjust for actual business conditions, making them useful in planning and cost control.

Organizations can compare actual results against the appropriate budget level rather than a single static budget.

Why Other Options Are Incorrect:

A. Exclude fixed costs: Fixed costs are included; only variable costs change with activity levels.

B. Exclude outcome projections: Flexible budgets still use projected outcomes but adjust them based on actual performance.

C. Red flag for weak control: Flexible budgets enhance control by allowing real-time adjustments, making them a best practice rather than a red flag.

IIA GTAG on Financial Management: Covers budgeting methods, including flexible budgeting.

IIA Standard 2120 – Risk Management: Encourages adaptive financial planning for effective risk management.

COSO ERM Framework: Recommends dynamic financial planning, including flexible budgeting.

Relevant IIA References:✅ Final Answer: Flexible budgets project data for different levels of activity (Option D).

Understanding the Three Lines of Defense Model:

First Line of Defense (Operational Management): Performs daily IT security tasks, such as blocking unauthorized traffic and encrypting data.

Second Line of Defense (Risk Management & Compliance): Monitors and reviews security controls, including disaster recovery testing and risk management activities.

Third Line of Defense (Internal Audit): Provides an independent assessment of IT security controls.

Why Option C (Review Disaster Recovery Test Results) Is Correct?

The second line of defense is responsible for monitoring and evaluating IT risk management processes, including disaster recovery and business continuity planning.

Reviewing disaster recovery test results ensures that the organization is prepared for IT disruptions and meets compliance requirements.

IIA Standard 2110 – Governance requires auditors to evaluate whether IT risk management activities (such as disaster recovery) are being effectively monitored.

Why Other Options Are Incorrect?

Option A (Block unauthorized traffic):

This is a first-line defense task, typically handled by IT security teams (e.g., firewall and intrusion detection system monitoring).

Option B (Encrypt data):

Encryption is part of daily IT security operations and is handled by the first line of defense.

Option D (Provide an independent assessment of IT security):

Independent assessments are the responsibility of internal audit (third line of defense), not the second line.

The second line of defense focuses on monitoring IT risk, making disaster recovery test review a key responsibility.

IIA Standard 2110 and the Three Lines of Defense Model confirm this role.
