Hierarchical Storage Technique for Maintaining Hop-Count to Prevent DDoS Attack in Cloud Computing

Abstract

In cloud environment, cloud servers providing requested services to the client as per request, sometimes may crash due to denial of service (DoS) attack. It prevents the legitimate users from getting service. DoS attack is accompanied by IP Spoofing so as to hide the location of flooding and to make every request dissimilar. Hop-count value is helps in Preventing DOS attack in cloud environment. This value is determined from received IP Packet. So, there is essential requirement of storage for storing hop-count value of clients. In this paper, we present an approach for storing hop-count value which helps to prevent DDoS attacks in cloud environment. This new approach of hop Count Storage is save searching time at the time of hop-count Filtering & helps in preventing DoS attack in cloud environment. Also, this method decreases the unavailability of cloud services to legitimate users, increases accessibility and reduces memory requirement for storing hop-count value.
