Detailed explanation-1: -The computer encrypts all data, including the payload and header, and appends a new header to it. IPSec transport mode encrypts only the data packet’s payload and leaves the IP header in its original form. The unencrypted packet header allows routers to identify the destination address of each data packet.
Detailed explanation-2: -IPsec is a group of protocols that are used together to set up encrypted connections between devices. It helps keep data sent over public networks secure. IPsec is often used to set up VPNs, and it works by encrypting IP packets, along with authenticating the source where the packets come from.
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.
