What is Network Encryption?

Network encryption is the process of encrypting data as it is transmitted over a public or private network to protect it from unauthorized access or tampering.

This can be done using a variety of encryption protocols, such as SSL (Secure Sockets Layer)/TLS (Transport Layer Security), IPSec (Internet Protocol Security), and VPN (Virtual Private Network).

Network encryption can be applied at different layers of the networking stack, depending on the specific protocol used.

Encryption at the application layer, such as HTTPS (Hyper Text Transfer Protocol Secure), encrypts specific types of network traffic, such as HTTP traffic, and requires an SSL certificate for secure communication.

Encryption at the transport layer, such as TLS, encrypts all traffic between two specific endpoints. Encryption at the Network layer, such as VPN, encrypts all traffic between two networks.

Network encryption protects sensitive information, such as financial data or personal information, from being intercepted by unauthorized parties.

It also helps to ensure the integrity of the data being transmitted and the authenticity of the parties involved in the communication.
