IPv6 approach for TCP SYN Flood attack over VoIP, Part V
By: Suhas Desai

In this paper, we describe and analyze a network based DoS at¬tack for IP based networks. It is known as SYN flooding. It works by an attacker sending many TCP connection re¬quests with spoofed source addresses to a victim's machine. Each request causes the targeted host to instantiate data structures out of a limited pool of resources to deny further legitimate access.

Part I
Part II
Part III
Part IV

7. Result Analysis

7.1 Most powerful and flexible L4-7 security and content networking test solution proven for:

7.2 Mix real VoIP calls (H.323 & SIP) over integrated DHCP, IPSec, PPPoE and 802.1 xs

7.3 Integrated IPv6, IPsecv6, VLAN, and SNMP support -Rapidly test next-generation dual-stack devices and Stress the management plane at the same time

7.4 Create a realistic mix of application traffic with H.323, SIP, RTSP, SNMP, messaging on each test interface, DoS. /spam /virus attacks with over 150 measurements.

8. Conclusion

This paper has described and analyzed a network based denial of service attack, called SYN flooding. It has contributed a detailed analysis for practical approach to application Performance validation for VoIP application with IPv6/IPv4 configurations and TCP SYN Flooding attacks over connection oriented networks.

To protect from DoS attacks for secure, scalable, high-availability IPV6 services over VoIP performance above methods proven better results. It has proved working also for spam and virus attacks over TCP connections with network tester methods of MoonV6.

9. Acknowledgement

We would like to thank Zlata Trhulj for design documentation of IPv6 services and Network tester methods presented at North American IPv6 Coalition Meeting-Reston, VA, 25 May, 2005.
