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

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.

A Cold Site is a remote disaster recovery facility that provides physical space and basic utilities such as electricity, internet, and telecommunications but does not include pre-installed servers, networking equipment, or other IT infrastructure. It requires a longer recovery time since the organization must procure, install, and configure necessary hardware and software before resuming operations.

A. Frozen Site – This is not a recognized term in IT disaster recovery planning.

C. Warm Site – A warm site has some pre-installed hardware and infrastructure but requires additional setup before full operation.

D. Hot Site – A hot site is a fully functional duplicate of the original site, with real-time data replication, allowing for immediate recovery.

The IIA Global Technology Audit Guide (GTAG) 10: Business Continuity Management emphasizes that organizations should classify recovery sites based on risk tolerance and recovery time objectives (RTO).

The IIA’s International Professional Practices Framework (IPPF) – Practice Advisory 2110-2 discusses IT continuity and disaster recovery as a critical element of internal audit assessments.

NIST Special Publication 800-34 (Contingency Planning Guide for Information Technology Systems) defines and categorizes disaster recovery sites, aligning with the cold site definition.

Explanation of the Other Options:IIA References & Best Practices:Thus, the correct answer is B. Cold Site.

Understanding Information Security Responsibilities:

Executive management sets the overall strategy and ensures resources are allocated for information security.

Internal auditors provide independent assurance on security effectiveness.

The board provides oversight and ensures that security risks are managed appropriately.

Line management is responsible for day-to-day operations, including the review and monitoring of security controls to ensure compliance with security policies.

Why Reviewing and Monitoring Security Controls is a Line Management Function:

Line management directly oversees operational security measures, ensuring that established controls are functioning effectively.

They address security gaps, enforce security policies, and report issues to senior management when necessary.

This aligns with IIA Standard 2120 – Risk Management, which requires management to implement and monitor risk mitigation controls.

Why Other Options Are Incorrect:

B. Dedicate sufficient security resources: This is the responsibility of executive management, as they control resource allocation.

C. Provide oversight to the security function: The board and executive management provide oversight, not line management.

D. Assess information control environments: Internal auditors assess control environments, ensuring compliance and effectiveness.

IIA Standards and References:

IIA Standard 2110 – Governance: Emphasizes the board’s role in overseeing security.

IIA Standard 2120 – Risk Management: States that management must monitor security risks.

IIA GTAG (Global Technology Audit Guide) on Information Security (2016): Outlines that line management is responsible for monitoring security controls on a daily basis.

Thus, the correct answer is A: Review and monitor security controls.
