One of the main protocols used in IPsec is the Authentication Header (AH) which provides integrity and authentication for IP packets.

Internet Protocol Security (IPsec) provides secure communication by authenticating and encrypting IP packets at the layer.

The IPSec protocol suite includes protocols for and encryption.

In IPSec, the Authentication Header (AH) protocol provides integrity and for data.

Transport mode in IPSec encrypts only the of the IP packet.

One of the main goals of IPSec is to provide end-to-end for communication.

IPsec can be used to protect data transmitted over the Internet, virtual private networks (VPNs), and other types of .

Internet Protocol Security (IPS) provides for communication over a network.

IPsec operates in two modes: transport mode, which encrypts only the payload of the IP packet, and tunnel mode, which encrypts the entire IP .

A VPN is commonly used to ensure and integrity of data transmitted over the internet.

The Encapsulating Security Payload (ESP) protocol in IPSec provides both and authentication.
