Internet Protocol (IP) : It is the method or protocol by which data is sent from one computer to another on the Internet. [1] Original version of the Internet Protocol that was first designed in 1983. [2] Security: “The quality or state of being secure—to be free from danger”. IPSec protects all the traffic over the network.

3. Introduction…
 Internet Protocol (IP) : It is the method or protocol by which data is
sent from one computer to another on the Internet. [1]
Original version of the Internet Protocol that was first designed in
1983. [2]
 Security: “The quality or state of being
secure—to be free from danger”.
IPSec protects all the traffic over the
network.

4. What is IPSec is…?
 Internet Protocol Security (IPSec): It is sets of protocols that
allow secure communication between two computer over an
unsecured network.
 IPSec has two goal:
To protect IP packets
Providing defense against
network attack . [3]

5.  IPSec secure network Traffic by using:
 Encryption
 Decryption
 Data signing [3]
(trusted source)

6. IPSec Works:
 IPSec used in Sending and receiving computer.
[6]

7. IPSec policies work:
 A security policy is a set of rules that define network
traffic at the IP layer.
 IPSec protects your private network from Internet
attacks through end-to-end security.
 IPSec policies must be carefully designed, configured,
coordinated and managed to ensure that IPSec
communication is successful. [7]

8. Three types of IPSec policies in the right pane:
 Client (Respond Only)
 Secure Server (Require Security)
 Server (Request Security) [4]

9. Component of IPSec:
IPSec Components:
IPSec contains the following elements:
 Encapsulating Security (ES): Provides confidentiality,
authentication, and integrity.
 Authentication Header (AH): Provides authentication and
integrity.
 Internet Key Exchange (IKE): Provides key management
and Security Association (SA) management. [5]
