“VCPHCF-RTT” estimation in private virtual cloud infrastructure

Abstract

For the security of proposed model of Private Virtual Cloud Infrastructure model, Security Agent technique has been designed to fight against IP-Spoofing based DDoS Attacks. Virtualization Enhancement has been done in Cloud using proposed and designed Security Agent VCPHCF-RTT. Performance Parameters have been analysed after introspection to existing cloud security mechanisms and tried to resolve focussed Research Problem, Issues and Challenges. VCPHCF-RTT improves the efficiency of the probabilistic HCF technique using HCF for virtual intermediate nodes between the Virtual Machines of Client VM and Server VM along with RTT. It helps in reducing the probability of guessing the RTT and VCHCF parameter values at the intermediate virtual routers by the attackers. VCPHCF-RTT technique has been examined to lessen down the probability of random IP spoofed packets correctly, efficiently and effectively. Through this, detection rate of the malicious packets have been improved up to 99% which is 80-85% improved for probabilistic Hop Count Filtering approach and 90% improved for conventional i.e. CHCF approach. It prevents the VM server from the IP spoofed DDoS attacks and it also eradicates the CPU cycles wastage. VCPHCF-RTT focuses on lessening down IP spoofing based attacks. The computation time has been reduced comparatively. Detection rate of malicious packets has been improved tremendously up to 99.7%.
