The IPSec protocol is configured in an organization's network in order to maintain a complete infrastructure for secured network communications.
IPSec uses four components for this.
Which of the following components reduces the size of data transmitted over congested network connections and increases the speed of such networks without losing data?

A. B. C. D.C.
The correct answer is C. IPcomp.
IPSec (Internet Protocol Security) is a protocol used to secure communication over an IP network. It provides data confidentiality, data integrity, and authentication. IPSec can be used to secure various types of communication, including site-to-site VPN, remote access VPN, and data transfer over the internet.
There are four components of IPSec:
Authentication Header (AH): Provides authentication and integrity of IP packets. AH does not provide confidentiality, and the original IP packet can be seen by eavesdroppers.
Encapsulating Security Payload (ESP): Provides authentication, integrity, and confidentiality of IP packets. ESP encrypts the original IP packet and adds a header to the encrypted packet.
Security Association (SA): Defines the parameters used by IPSec to secure communication, including encryption algorithms, authentication methods, and keys.
Internet Protocol Compression Protocol (IPcomp): Reduces the size of data transmitted over congested network connections and increases the speed of such networks without losing data. IPcomp works by compressing the IP packet before it is sent over the network, and decompressing it at the receiving end.
In summary, IPcomp is a component of IPSec that provides compression of IP packets to increase network speed and reduce congestion. It does not provide authentication, integrity, or confidentiality of IP packets like AH and ESP. IKE (Internet Key Exchange) is a protocol used to establish SA between two devices. It does not provide compression, authentication, integrity, or confidentiality of IP packets.
