Abstract

In the past decade, it has been found that DDoS has proved to be the most dangerous attack. IP spoofing is one of the kinds of DDoS attack which is emerging as a big threat in today’s world of technology. The Proposed Framework is a unique technique composed of distributed firewalls and hop count based filtering, it can be used to prevent such kind of DDoS attack. At The primary level, distributed firewalls filters the IP addresses which can be either Internet or Intranet. Along with this it also provide various other advantages such as reducing the dependency of network topology. At secondary level, hop count and TTL based filtering provides more secure level of filtration. In this paper, we have proposed a new framework which reduces the limitations of previous conventional techniques.
