COMPUTER FUNDAMENTALS

Detailed explanation-1: -Explanation: A remote-access VPN typically depends on either Secure Sockets Layer (SSL) or IP Security (IPsec) for a secure connection over public network.

Detailed explanation-2: -IPsec VPNs typically are used to connect a remote host with a network VPN server; the traffic sent over the public internet is encrypted between the VPN server and the remote host. IPsec enables the communicating hosts to negotiate which cryptographic algorithms are to be used to encrypt or authenticate data.

Detailed explanation-3: -When it comes to corporate VPNs that provide access to a company network rather than the internet, the general consensus is that IPSec is preferable for site-to-site VPNs, and SSL is better for remote access.

Detailed explanation-4: -IPsec VPN securely interconnects entire networks (site-to-site VPN) OR remote users with a particular protected area such as a local network, application, or the cloud. SSL VPN creates a secure tunnel from the host’s web browser to a particular application.

Detailed explanation-5: -An SSL VPN is a type of virtual private network (VPN) that uses the Secure Sockets Layer (SSL) protocol–or, more often, its successor, the Transport Layer Security (TLS) protocol–in standard web browsers to provide secure, remote access VPN capability.
