Detection and Mitigation Of DDoS Attack Against Web Server
Dhruv A. Patel,  Prof. Hasmukh Patel
In the modern computer world, use of the internet is increasing day by day. However, the increasing use of the internet creates some security issues. These days, such new types of sophisticated security attacks occurred and it is not easy to detect and prevent those attacks effectively. One common method of attack involves sending large amount of request to site or server and server will be unable to handle such huge requests and site will be offline for many days depends upon the attack. This is major security threat to internet services and most critical attack for cyber security world is called distributed denial of service (DDOS) attack. How to detect and prevent against a DDOS attack is currently a hot topic in both industry and academia. Traditionally, DDOS attacks are carried out at the network layer. Since many studies have noticed this type of attacks and have proposed different schemes and solutions (e.g., network measure or anomaly detection) to protect the network. It is not as easy as in the past for attackers to launch the DDOS attacks based on network layer. So, attackers shift their offensive strategies to application layered attacks and establish a more sophisticated type of application layer DDOS attacks such as HTTP flooding. The significance of the application layer DDOS attack and increased occurrence and strength of attack led my work to use creative, effective and efficient mechanism that address the DDOS flooding problem. Here, I am looking forward to detect and mitigate the effect of DDOS attack against web server. I will propose such a mechanism that will detect DDOS attack, differentiate the attack traffic from normal traffic, and mitigate the effect of DDOS attack. My main goal is to increase the availability of web server for legal users.
