Detailed explanation-1: -Explanation: IPSec is a set of protocols used to provide authentication, data integrity and confidentiality between two machines in an IP network. In the TCP/IP model, it provides security at the IP layer i.e. the network layer.
Detailed explanation-2: -What is IPsec? IPsec helps keep private data secure when it is transmitted over a public network. More specifically, IPsec is a group of protocols that are used together to set up secure connections between devices at layer 3 of the OSI model (the network layer).
Detailed explanation-3: -IPsec is used for protecting sensitive data, such as financial transactions, medical records and corporate communications, as it’s transmitted across the network. It’s also used to secure virtual private networks (VPNs), where IPsec tunneling encrypts all data sent between two endpoints.
