What type of VPN needs to be enabled in Device Access settings?

The correct answer is SSL. Enabling SSL VPN in the Device Access settings is essential for allowing secure remote connections to the network. SSL (Secure Sockets Layer) is a protocol that provides an additional layer of security by encrypting the data transmitted between the users and the firewall. With SSL VPN, users can access internal resources over a secure connection using a web browser, making it user-friendly and suitable for environments where remote access is required.

SSL VPNs are particularly advantageous in situations where simplicity and security are prioritized, as they do not require specific VPN client software to be installed on user devices. Users can connect through any device with a modern web browser, facilitating quick access to applications and resources without cumbersome configurations.

While other VPN types like IPsec, L2TP, and PPTP have their own use cases and security protocols, they typically involve more complex configurations and may require additional client installations, which can hinder usability for remote users.
