摘要：ABSTRACT : With the rapid development of information technology, internet has affect the people in all aspects such as public utilities, telecommunication, financial transaction and defense system, all depends on information technology and their security. The widespread deployment of new technologies had maximized the use of internet to a great extent. But at the same time, the potential attackers are success on discovering new ways to attack. Botnet is one of the most serious emerging threats and it refers to a number of compromised computers within a network. Malicious activities which are performed by a botnet are DDoS, spam, click fraud, phishing, identity theft, sniffing traffic, keylogging etc. DDoS attack can significantly degrade the performance of a network or can completely disconnect a machine to achieve resource overloading. The objective of this dissertation is dealing with DDoS attack. This work is dividing into three phase. In first phase, we are simulating a botnet environment. In second phase, we are performing UDP flooding of DDoS attack. In third we are applying queuing theory to overcome the DDoS attack.
