Answer:
Transport mode
Step-by-step explanation:
The host-to-host transport mode of internet protocol security (IPsec) is mostly used between two host devices or between a user and a server. When you go online and Google something, what you have done is send a packet request to a server. The IPsec’s transport mode offers secure protection to parts of this IP packet. The packet consists of the original IP header and an IP payload (TCP header and data). In transport mode, only the IP payload is encrypted. The original IP header is not.
