The Distributed Denial of Service (DDoS) attack is becoming more sophisticated and complex with the increase in the skills of attackers and so, has become one of favorite weapon for the cyber criminals to temporarily suspend or crash the services of a host connected to the Internet and till now nearly every big site had been a victim of this attack.Since 2013, Hackers have adopted new tactics to boost the sizes of Distributed Denial of Service (DDoS) attack known as ‘Amplification Attack’, leveraging the weakness in the UDP protocols. One of the commonly used by hacker is (Domain Name System) DNS Reflection Denial of Service (DrDoS).The DNS Reflection Denial of Service (DrDoS) technique exploits security weaknesses in the Domain Name System (DNS) Internet protocol. Using Internet protocol spoofing, the source address is set to that of the targeted victim, which means all the replies will go to the target and the target of the attack receives replies from all the DNS servers that are used. This type of attack makes it very difficult to identify the malicious sources.
