The network is no longer the network of the past. The focus of the network began to change a few years ago. It moved from the company's data center to the cloud.

Detailed interpretation of IPSec protocol

Image
IPSec (Internet Protocol Security) is a set of open network security protocols formulated by IETF (Internet Engineering Task Force). It is not a single protocol, but a collection of protocols and services that provide security for IP networks. It provides high-quality, interoperable, and cryptographic-based security guarantees for data transmitted on the Internet. IPSec mainly includes security protocols AH (AuthenticationHeader) and ESP (Encapsulating Security Payload), key management exchange protocol IKE (Internet KeyExchange), and some algorithms for network authentication and encryption. IPSec mainly uses encryption and verification methods. The authentication mechanism enables the data receiver of IP communication to confirm the true identity of the data sender and whether the data has been tampered with during transmission. The encryption mechanism guarantees the confidentiality of the data by encrypting the data to prevent the data from being eavesdropped during transmission. T...
