When an internal auditor calculates the mean (average), median (middle value), and range (difference between highest and lowest values) of a data population, the primary purpose is to assess the distribution of data and detect anomalies. Let’s analyze the answer choices:

Option A: To inform the classification of the data population.

Incorrect. Classification typically involves categorizing data into specific groups, which requires different statistical or analytical techniques like clustering or decision trees. Mean, median, and range are more useful for identifying distribution patterns.

Option B: To determine the completeness and accuracy of the data.

Incorrect. While summary statistics can highlight extreme values, completeness and accuracy are usually assessed through data reconciliation, validation checks, and comparison with source records.

Option C: To identify whether the population contains outliers.

Correct.

The range (difference between the largest and smallest values) helps to detect extreme values.

The mean and median can show whether the data is symmetrical or skewed (which may indicate outliers).

If the mean is significantly different from the median, it suggests potential outliers pulling the average in one direction.

IIA Reference: Internal auditors use data analytics to detect anomalies and potential fraud by identifying outliers. (IIA GTAG: Auditing with Data Analytics)

Option D: To determine whether duplicates in the data inflate the range.

Incorrect. Duplicates may affect the data set, but range calculations alone do not determine whether duplicates exist. Duplicate identification usually involves checking for repeated entries, not just extreme values.

To effectively mitigate and manage risks during a crisis, organizations must implement a combination of preventive and reactive measures:

Preventive measures: These are proactive steps taken before a crisis to reduce the likelihood of occurrence (e.g., risk assessments, internal controls, security protocols).

Reactive measures: These are actions taken after a crisis occurs to minimize damage, restore operations, and recover from the event (e.g., business continuity plans, incident response strategies).

(A) Incorrect – Only preventive measures.

While prevention is essential, not all crises can be avoided. Organizations also need response mechanisms.

(B) Incorrect – Alternative and reactive measures.

Alternative measures (e.g., backup systems) are part of risk management, but without prevention, risks may escalate.

(C) Incorrect – Preventive and alternative measures.

Alternative measures (e.g., backup resources) help maintain operations but do not directly address crisis response.

(D) Correct – Preventive and reactive measures.

Best practice in risk management includes both preventing crises and responding effectively when they occur.

IIA’s Global Internal Audit Standards – Crisis Management and Business Resilience

Emphasizes the need for both prevention and response strategies.

COSO’s ERM Framework – Risk Management in Crisis Situations

Recommends a combination of risk avoidance, mitigation, and crisis response.

ISO 22301 – Business Continuity Management

Highlights the importance of preventive controls and reactive response planning.

Analysis of Answer Choices:IIA References and Internal Auditing Standards:

The first step in a project management plan is to break the project into manageable components, known as Work Breakdown Structure (WBS). This step ensures clarity, task allocation, and effective tracking.

(A) Estimate time required to complete the whole project.

Incorrect: Time estimation comes after breaking the project into smaller tasks.

(B) Determine the responses to expected project risks.

Incorrect: Risk management is important but is planned after defining project tasks and scope.

(C) Break the project into manageable components. (Correct Answer)

Dividing the project into smaller tasks (WBS) helps in resource allocation, scheduling, and risk assessment.

IIA GTAG 12 – Project Risk Management suggests using WBS to define tasks clearly.

(D) Identify resources needed to complete the project.

Incorrect: Resources can only be allocated effectively after defining project components.

IIA GTAG 12 – Project Risk Management: Recommends Work Breakdown Structure (WBS) as the first step in project planning.

PMBOK (Project Management Body of Knowledge): Defines WBS as the foundation of project planning.

Analysis of Each Option:IIA References Supporting the Answer:Thus, the correct answer is (C) Break the project into manageable components, as this is the first step in structuring and planning a successful project.

Automated attacks that attempt to exploit weak or leaked passwords—such as credential stuffing, brute force attacks, and dictionary attacks—pose a significant cybersecurity risk. Implementing two-step verification (also known as multi-factor authentication, or MFA) is one of the most effective measures to mitigate these threats.

Why Two-Step Verification is Effective (B - Correct Answer)

Multi-factor authentication (MFA) adds an additional security layer beyond a password, requiring a second factor such as a one-time code sent to a mobile device, biometric authentication, or a security key.

Even if an attacker obtains a password, they cannot access the account without the second authentication factor.

The IIA Global Technology Audit Guide (GTAG) 1: Information Security Management emphasizes the use of multi-factor authentication to prevent unauthorized access.

Why Other Options Are Less Effective:

Option A: Changing passwords every two years

Ineffective because attackers often use compromised credentials that may be recent. Best practices recommend regular password updates but coupled with MFA.

The IIA's GTAG 16: Identity and Access Management highlights that password rotation alone does not fully protect against automated attacks.

Option C: Using a VPN when out of the office

Irrelevant to password attacks. A VPN encrypts data and secures network connections but does not prevent brute force or credential stuffing attacks.

The IIA GTAG 17: Auditing Network Security discusses VPNs for secure remote access but does not consider them a solution for password-based attacks.

Option D: Using antivirus and security tools

While important for overall security, these tools cannot prevent attacks that exploit stolen or weak passwords.

The IIA GTAG 15: Information Security Governance states that security tools should be combined with authentication controls like MFA for best protection.

GTAG 1: Information Security Management – Recommends multi-factor authentication to prevent unauthorized system access.

GTAG 16: Identity and Access Management – Highlights the limitations of password-only security and supports multi-factor authentication.

GTAG 17: Auditing Network Security – Covers VPN usage but does not consider it a solution for password attacks.

GTAG 15: Information Security Governance – Discusses the role of security tools and authentication in securing user accounts.

Step-by-Step Explanation:IIA References for Validation:Thus, requiring two-step verification (B) is the most effective control against automated password attacks.
