Today, with the Evolution of technology and tools like computer systems, mobiles, and tablets pieces use these http as default protocol. The fact is a huge amount of data transactions are being processed due to these the http protocol. Because of this reason http protocol is becoming a target to attackers. It is important to analyze traffic between various protocols to seek attack attempts and also take certain measures to prevent them from these attackers. In this we are going to evaluate the effectiveness of web application firewall by using confusion matrix plots we user studio as a tool for finding out the results. We focus on the precision, recall, sensitivity, accuracy and false positive rate with the help of random numbers. We used different classifiers to test the detection accuracies. The experiments show that we can also find effectiveness in a better way.
