IIA Updated IIA-CIA-Part3 Exam Questions and Answers by zaviyar

Comprehensive and Detailed In-Depth Explanation:

Gain sharing is a compensation program where employees receive bonuses tied directly to the company's cost-saving measures and productivity improvements. This approach aligns employees' interests with organizational goals by rewarding them for identifying and implementing efficiencies that reduce costs. Unlike profit sharing, which is based on overall profitability, gain sharing focuses specifically on performance improvements that lead to cost savings. Commissions are typically related to sales performance, and pensions are long-term retirement benefits not directly linked to immediate cost-saving efforts. Therefore, gain sharing is the most indicative of targeting cost-saving objectives.

A cold site is a disaster recovery option that provides only basic infrastructure (such as power, space, and network connectivity) but does not have pre-installed IT equipment such as servers and storage. Organizations must procure and install servers and restore data before resuming operations, leading to longer recovery times.

Let’s analyze each option:

Option A: Data is synchronized in real-time

Incorrect.

Real-time data synchronization is a feature of hot sites, which have fully operational infrastructure and data replication.

Cold sites do not support real-time synchronization because they lack servers and storage.

Option B: Recovery time is expected to be less than one week

Incorrect.

Cold sites require significant setup time since servers and infrastructure must be procured, configured, and installed.

Recovery time can often exceed one week, depending on the complexity of IT systems.

Option C: Servers are not available and need to be procured

Correct.

A cold site lacks computing hardware (e.g., servers, storage, network devices), meaning the organization must purchase or transport servers to the site before recovery can begin.

IIA Reference: Internal auditors assess disaster recovery strategies, including the limitations of cold sites and their impact on business continuity. (IIA GTAG: Auditing Business Continuity and Disaster Recovery)

Option D: Recovery resources and data restore processes have not been defined.

Incorrect.

Even though a cold site lacks IT infrastructure, the organization still has a disaster recovery plan, which includes predefined recovery steps, resource planning, and data restoration procedures.

Thus, the verified answer is C. Servers are not available and need to be procured.

To prevent unauthorized wireless network access, the strongest control is to require access through a Virtual Private Network (VPN). A VPN encrypts data and ensures that only authorized users with proper credentials can connect securely.

Encryption & Secure Communication: VPNs use strong encryption protocols (e.g., AES-256) to protect data from unauthorized access.

Restricted Access Control: Users must authenticate through a secure VPN gateway, reducing the risk of unauthorized access.

Compliance with IT Security Standards: VPNs are recommended by security frameworks such as NIST 800-53, ISO 27001, and CIS Critical Security Controls.

Option B (Logging devices that access the network, including date, time, and user identity): Logging is important for monitoring but does not prevent unauthorized access—it only records it after the fact.

Option C (Tracking all mobile device physical locations and banning access from non-designated areas): Geofencing can help restrict access but is not as secure as a VPN, and attackers could spoof locations.

Option D (Permitting only authorized IT personnel to have administrative control of mobile devices): While restricting administrative control is good practice, it does not prevent unauthorized users from connecting to the network.

IIA’s GTAG on IT Security & Cybersecurity Risks highlights VPNs as a critical security measure to prevent unauthorized access.

ISO 27001 (Annex A.13) – Network Security Management recommends encrypting data transmissions to secure wireless network access.

NIST 800-53 (SC-12, SC-13, SC-28) emphasizes using VPNs for secure remote and wireless network access.

Why Option A is Correct (VPN):Why Other Options Are Incorrect:IIA References:Thus, the most appropriate answer is A. Allowing access to the organization's network only through a virtual private network (VPN).

When employees work from home, secure remote access to the organization's network is essential to protect data and ensure confidentiality. A Virtual Private Network (VPN) is the best option for enabling this securely.

Correct Answer (D - A Virtual Private Network (VPN))

A VPN creates a secure, encrypted connection between the employee's device and the organization’s internal network.

It prevents unauthorized access by ensuring that data is transmitted securely over the internet.

The IIA GTAG 17: Auditing Network Security recommends VPNs for secure remote work environments to prevent cyber threats.

Why Other Options Are Incorrect:

Option A (A Wireless Local Area Network - WLAN):

A WLAN is used within an office or home environment, but it does not provide secure remote access to an organization's network.

Option B (A Personal Area Network - PAN):

A PAN connects devices like smartphones and laptops within a short range (e.g., Bluetooth), but it is not suitable for secure remote access.

Option C (A Wide Area Network - WAN):

A WAN connects multiple locations, but it does not provide encryption or remote security like a VPN.

IIA GTAG 17: Auditing Network Security – Recommends VPNs for secure remote access.

IIA Practice Guide: Auditing IT Security Controls – Covers VPNs as a key security control for remote work.

Step-by-Step Explanation:IIA References for Validation:Thus, D is the correct answer because a VPN ensures secure, encrypted communication for employees working from home.
