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.

IIA Three Lines of Defense Model

COBIT Framework – IT Governance & 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).

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 data privacy policy outlines how an organization collects, stores, processes, and protects personal data. It should comply with global data protection regulations such as GDPR, CCPA, and IIA guidelines on data security.

(1) Stipulations for deleting certain data after a specified period of time. ✅

Correct. Many data protection laws (e.g., GDPR Article 5) require organizations to delete personal data after a defined retention period to reduce data breach risks.

(2) Guidance on acceptable methods for collecting personal data. ✅

Correct. A privacy policy must define legal and ethical ways to collect personal data (e.g., user consent, lawful processing).

(3) A requirement to retain personal data indefinitely to ensure a complete audit trail. ❌

Incorrect. Retaining personal data indefinitely violates most data privacy regulations (e.g., GDPR Right to Be Forgotten). Data must be stored only for as long as necessary.

(4) A description of what constitutes appropriate use of personal data. ✅

Correct. A privacy policy should clearly define how collected data can and cannot be used to prevent misuse and ensure compliance.

IIA GTAG – "Auditing Privacy Risks"

IIA Standard 2110 – Governance (Data Protection & Privacy)

GDPR (General Data Protection Regulation) – Articles 5 & 17 (Data Retention & Deletion)

Analysis of Answer Choices:IIA References:Thus, the correct answer is C (1, 2, and 4 only) because data should not be retained indefinitely, and the policy must include data collection, retention, and appropriate usage guidelines.
