Preventing ADDOS Attack by Using Secure TRNG Based Port Hopping

Now a day`s each and every where we are using client-server communication for different information service systems. Normally client server communication can be differentiating by using IP Address and Protocol Port number from one machine to another machine. In network environment we are already having DOS/DDOS Attacks Another Subset of this attack scenario is DOS/DDOS attack is Application Denial of Service(ADOS)attack ,In this the adversary attacks open Ports/Ideal ports present at server side for this the adversary Know need huge machines ,zombie systems and no need sending packets of data with high bandwidth. To control this type of A-DOS attacks the existing enterprise security devices are not suitable like firewalls, anti-viruses and IDS/IPS Systems why because the adversary not using high bandwidth, spam messages, zombie`s or botnet`s for their attack scenarios.To safeguard this type of DOS/DDOS or Application denial of service attacks we are having some port hopping mechanisms i.e Port hopping by using Pseudo Random Number Generation (PRNG)based port hopping ,Acknowledgement based port hopping and proactive Reinitialization based on this existing once and their disadvantages like in PRNG attackers can predict the random number generation by using pre-calculated list or based on mathemathical functions .we introduce new port hopping technique i.e True Random Number Generation based port hopping
