Explanation:
IPSec is an interoperable standard developed by Internet Engineering Task Force to secure the data
sent between two computers on an IP network. It protects the data by providing the following two
services:Data Authentication: IPSec can be configured to ensure that each IP packet received from a trusted
party is exactly originated from that party. It can be configured to ensure that data is not altered in
between (from source to destination). It can also be configured to ensure that no packet is
duplicated in the transit.
Encryption: IPSec is used to encrypt data so that it can’t be read if captured during transmission.
