Denial of service (DoS) attacks has turned out to be a chief danger to existing computer systems. To include a superior perceptive on DoS attacks, this piece of writing gives an outline on accessible DoS attacks and main security tools in the web-world and wireless systems. Above all, here system supported and host supported DoS attack systems are expressed to demonstrate attack standards. DoS attacks have been categorized as per their main attack features. Pre transmitted counter-offensive systems are too evaluated, together with chief security goods in use and delegated security techniques in study. Then, by the use of adaptive threshold, the possibility of a DDoS attack is investigated. In order to achieve more accuracy, another method, computing flow initiation rate, is used alongside. After observation of the results of this two methods review, according to the described conditions, the existence of an attack is confirmed or rejected, or this decision is made at the next step of the algorithm, with further study of flow statistics of network switches by the perceptron neural network.
