Focus An organization has decided to have all employees work from home.

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.
