Which technology is commonly used to establish a secure connection for remote employees accessing a company's private LAN?

1. VPN

2. RADIUS

3. IPsec

4. Proxy server

The correct answer is: IPsec

The technology commonly used to establish a secure connection for remote employees accessing a company's private LAN is a VPN (Virtual Private Network). A VPN creates a secure and encrypted tunnel over the internet, allowing remote users to connect to the company's network as if they were physically on-site. This is essential for protecting sensitive data transmitted over public networks and helps maintain the confidentiality and integrity of the information being accessed or shared. While IPsec is a protocol suite used to secure internet protocol communications and can be part of the implementation of a VPN, it does not by itself provide the overall solution that VPN technology does. RADIUS (Remote Authentication Dial-In User Service) is primarily used for authentication and authorization, but it does not create the secure connection by itself. A proxy server can be utilized for various functions, such as filtering and caching web traffic, but it does not directly establish a secure connection in the way a VPN does. Thus, the primary and comprehensive solution for secure remote access to a private LAN is the VPN.
