(also network security encryption)
Network encryption is a cybersecurity method of encoding data carried over a network to safeguard it from unauthorized access, interruption, or modification. Users apply network encryption to protect the confidentiality, integrity, and authenticity of the data between two or more devices on a network. This process implements different methods, standards, and tools that make the data unreadable, such as anonymization, encryption, or data masking. The encryption method involves transforming plain text data into ciphertext with the help of an encryption algorithm and a secret key. Only the authorized receiver with the right key may decrypt the ciphertext and restore it to its original state. It is possible to implement network encryption at the application, transport, and network layers of the network stack. Secure communication protocols like HTTPS or IPsec usually use it.
