  1. FINAL YEAR PROJECT

  2. IMPLEMENTATION OF VPN USING IPSEC

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

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

  11. Flow Diagram: Start connectivity Data security problem Different vpn Vpn ipsec Site-to-site vpn Remote vpn End

  12. IMPLEMENTATION1st scenario • PROBLEM Site1 Site2 DATA DATA INTERNET THIS IS A HUGE PROBLEM Data is viewed by third party HACKER

  13. IMPLEMENTATION1st scenario • SOLUTION Site1 Site2 INTERNET DATA DATA VPN TUNNEL Third party is unable to view data HACKER

  14. IMPLEMENTATION2ND scenario • REMOTE VPN Site INTERNET VPN LAPTOP (MOBILE USER)

  15. TOOLS • Routers (security IOS) • VPN Concentrator • Sniffer (ethereal)

  16. ADVANTAGES • Cost Effective • No Additional Equipment Required • No Distance Limitation

  17. ANY QUESTION??
