FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -L2TP or Layer 2 Tunneling Protocol is a tunneling protocol that is usually combined with another VPN security protocol like IPSec to create a highly secure VPN connection. L2TP creates a tunnel between two L2TP connection points and IPSec protocol encrypts the data and handles secure communication between the tunnel.

Detailed explanation-2: -Secure Shell, or SSH, is used to create a secure channel between a local and remote computer. While SSH is commonly used for secure terminal access and file transfers, it can also be used to create a secure tunnel between computers for forwarding other network connections that are not normally encrypted.

Detailed explanation-3: -A Secure Tunnel provides endpoint-to-endpoint connections across a hybrid network without opening firewall rules in an enterprise network. It allows access between different networks through TCP over HTTPS technology.

Detailed explanation-4: -VPN allows you to access the restricted sites with a secure connection, while firewall can only create a layer of restrictions that you have accessed. Firewalls use your choice to block access to certain sites. While using a VPN, one can access the same site over a long period of time.

Detailed explanation-5: -In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet.
