Working mechanism of IPSec on AR series routers

Huawei AR series routers support IPSec. Most data is transmitted in plain text on the Internet. This transmission mode has many potential risks. For example, bank account and password data may be intercepted or tampered, and user identities are used, and malicious attacks occur. After IPSec is deployed on the network, transmitted IP data is protected to reduce risks of information leakage. IPSec is a security protocol suite defined by the Internet Engineering Task Force (IETF). IPSec secures data transmission on the Internet through data origin authentication, data encryption, data integrity check, and anti-replay functions.
