The document presents an overview of Internet Protocol Security (IPsec), which is a set of protocols designed to enable secure communication over unsecured networks. It describes IPsec's functions, including the protection of IP packets through encryption, decryption, and data signing, and highlights the importance of carefully managed security policies. Key components of IPsec include encapsulating security, authentication header, and internet key exchange.

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]
