PREVENTING CLOUD SYSTEMS AGAINST DDOS ATTACK USING HOP COUNT FILTER APPROACH

Abstract

Cloud Computing is the most dynamic field characterized by IT Industry. Most probably every industry, and some parts of it , are migrating their data to the cloud. The cloud has become the part of the critical global infrastructure. Security has become the major concern for this computing environment. The Cloud has the distributed nature, so it has become the target of distributed attacks like DDoS and DoS. DDoS and Simple DoS attack us one of the biggest threat in the Cloud networks which prevents the authorized users from using the Cloud Services. Cloud Servers can be crashed down , when it gets too many unnecessary requests or SYN Packets. So, the appropriate solution must be identified to strengthen the security and privacy of the cloud. In this Paper, we have proposed the algorithm, which uses Hop Count Filter Approach, which can block the spoofed packets and can strengthen the security of the cloud
