regarded as being transmitted on a dedicated data network. This ensures data
security.
5.3.1 IPsec
IPsec is a group of open network security protocols developed by IETF. At the IP
layer, the data source authentication, data encryption, data integrity, and anti-
replay functions are used to ensure the security of data transmission between
communication parties on the Internet. This reduces the risk of leakage and
eavesdropping, ensures the integrity and confidentiality of data, and ensures the
security of service transmission for users.
Scenario: Data is transmitted between the subnet (192.168.1.0/24) of headquarters
A and the subnet (172.16.1.0/24) of customer branch B through gateway A and
gateway B. The transmission channels of gateway A and gateway B are encrypted over
IPsec, to protect the security of data transmission between headquarters A and
customer branch B.
Method for encrypting the transmission channels of gateway A and gateway B over
IPsec:
