Domineering Analysis & Mitigation of IP-SEC VPN Using GNS3


Engr. Maria Abdullah and Najeed Ahmed Khan


Vol. 17  No. 4  pp. 245-250


The needs of Internet have been expanded, a definitive test for system architects is to permit the focused on systems to get to delicate corporate data in a protected way by means of Internet. VPN engineering is an innovation that remains stood in presence for certain time and it exists a demonstrated innovation that permits organizations to transmit corporate information safely and financially over an expansive separation. IP Security is a typical set of rules for acquiring the Internet Protocol (IP) communication by Verification and encryption of transmission of an information stream. The aim of this research is to find out the effect of implementing the IP Security tunnel on edge routers. AES - Encryption algorithm, SHA - Hashing algorithm and Pre-shared - Authentication keys are used in the proposed framework. Also focus is on the TCP and ICMP execution assessment on a VPN environment with distinctive IPsec with tunnel & without tunnel to identify Security, Delay & CPU utilization as an overheads.
