What typifies the communication method in a clientless VPN?

1. Relies on custom-built client applications

2. Uses proprietary protocols for security

3. Communicates directly with the VPN concentrator

4. Requires VPN connection handlers to work

The correct answer is: Communicates directly with the VPN concentrator

The characteristic feature of a clientless VPN is that it allows users to establish a secure connection without the need for a pre-installed VPN client application. This is typically achieved through a web browser that communicates directly with the VPN concentrator. This method enables users to access corporate resources securely from remote locations without the logistical overhead of installing dedicated software. This communication is often conducted using standard protocols like SSL or HTTPS, facilitating secure access via the browser. This flexibility makes clientless VPNs particularly useful for situations where users may be accessing services from public or shared computers. In contrast, the other options involve requirements that are not aligned with the clientless approach. For example, custom-built applications suggest a dependence on specific software, while proprietary protocols imply a level of exclusivity that negates the versatility of using standard web browsers. Additionally, dependency on VPN connection handlers indicates that there would be a necessary installation or configuration of software, which clientless VPNs specifically avoid.
