摘要：Denial of service (DOS) attacks present an internet ¨Cwide threat. SYN flooding is one of the DOS attack that degrades the performance of the system. It is the most powerful attack used by hackers to harm the organization. It causes service outages and loss of millions, depending on the duration of attack. SYN flood DOS attack involves sending too many SYN packets to the destination. The attack use up the resources and memory of the server. This can lead to the hang of the server machine. Dos attacks are a persistent problem for several reasons. First, they are one of the earliest attacks to perform, and they attain quick results. They are the most common attacks that an administrator with a system that's always connected to the internet can expect. Well it is an attempt to make a system or server unavailable for legitimate users and, finally, degrades the service. This is accomplished by flooding the server's request queue with fake requests. After this, server will not be able to interact with the requests of legitimate users. This paper focused on dos attack and how to overcome it using ¨DHADOOP¡¬. For this here an open source tools and softwares are used. We proposed a technique to detect flooding based attack at hadoop datanode and analysed the working of hadoop distributed file system. We have also shown hadoop's effectiveness in attack scenario, discussed various motivation for deployment
