DDoS Attack detection and Prevention in Private Cloud Environment

DDoS Attack is launched by attackers by exploiting all the vulnerabilities in the present system design. The sole dependence of the Internet for many of the activities is also a main reason for the losses that are faced by the majority of the human population. In spite of the great amount of services that are offered by the Internet it also has the responsibility of providing security measures against the malicious activity that are caused by the attackers. The Web Applications that are deployed in the Server architecture are liable to get exposed to the DDoS Attack apart from other attacks such as SQL Injection, XSS, CSRF, etc. It is disappointing that for the eradication of this DDoS attack, the vulnerabilities causing this attack to get launched are not completely traced. To solve this problem, in this current work the countermeasure against this situation was developed. The experiment involves in performing the DDoS Attack targeting the Web application deployed in Apache Web server in Private Cloud Environment. To correctly differentiate the DDoS Attack traffic from the normal traffic flood , the threshold of the attack traffic attempted on SCO Website was utilized. The Hit rate was calculated from the NASA datasets and compared with the current work. The results obtained from Tableau graph with the help of NASA datasets for Flash crowd traffic were utilized in understanding the traffic patterns available with access matrix. The DDoS Attack was performed using the attack causing tool and with the help of java coding to analyze the attack patterns stored in the log files of Tomcat Webserver. The Attack was detected at a faster rate once the threshold had reached the higher traffic limit realized in the 1998 World cup Football datasets and the Attack traffic was stopped immediately through Servlet and XML Coding and the results were validated.
