💡 A virtual private network (VPN) allows remote employees to securely access the organization's internal network over the public internet. It encrypts the data transmitted between the remote device and the corporate network, protecting sensitive information from unauthorized access. A. A wireless local area network (WLAN) is typically confined to a limited area (such as an office) and does not inherently provide secure remote access. B. A personal area network (PAN) is used for connecting personal devices (e.g., smartphones, tablets) and is not designed for secure organizational network access. C. A wide area network (WAN) connects multiple locations, but by itself, it does not ensure secure remote access for home-based employees.
