Detailed explanation-1: -The two most commonly used technologies in remote access VPNs are IPSec and SSL. IPsec is the most widely used VPN technology. Because it provides protection at the IP level layer (Layer 3), it can be deployed to secure communication between the office network and a host computer used at home.
Detailed explanation-2: -VPNs can securely connect a user to a company’s internal network or to the public Internet. Businesses typically use a VPN to give remote employees access to internal applications and data, or to create a single shared network between multiple office locations.
Detailed explanation-3: -It keeps all communication between remotely-located employees safe from the cybercriminals, without disturbing the flow of work. A VPN uses a range of encryption technologies like IP security (IPSec), layer 2 tunneling protocol (L2TP)/IPSec, as well as secure sockets layer (SSL) and transport layer security (TLS).
Detailed explanation-4: -A VPN connection establishes a secure connection between you and the internet. Via the VPN, all your data traffic is routed through an encrypted virtual tunnel. This disguises your IP address when you use the internet, making its location invisible to everyone. A VPN connection is also secure against external attacks.
