2. FINAL YEAR PROJECT

3. IMPLEMENTATION OF VPN USING IPSEC

4. GROUP MEMBERS M.UZAIR NASIR 2K5-CSE-153 AHSAN EJAZ 2K5-CSE-163
RANA.M.KAMRAN 2K5-CSE-164
HUMAYUN KHAN K5-CSE-169

5. VPN
To Create a Secure tunnel over the public network (internet) is called Virtual Private Network

6. VPN Types Overlay VPN Peer-to-Peer VPN Layer 2 VPN Layer 3 VPN
L2TP
Layer 3 VPN
IPSec
GRE Tunneling
Peer-to-Peer VPN
MPLS VPN

7. IPSec VPN
IPSec is a set of security protocols and algorithms used to secure data at the network layer

8. WHY WE USE IPSEC? IP Packets have no inherent security
No Way To Verify
The claimed sender is a true sender
The data has not been modified in transit
The data has not been viewed by third party
IP sec Provide Automated Solution for these areas

9. IPSec Security Features
Data Confidentiality
Data Integrity
Data origin Authentication

10. IPSec Protocols
IPSec uses two main protocols to create a security framework
Encapsulating Security Payload (ESP)
Authentication Header (AH)

11. IPSec VPN We can implement IPSec VPN in different Scenario
Site-to-Site VPN
Remote Access VPN
