Web logs play the crucial role in detecting web attack. However, analyzing web logs become a challenge due to the huge log volume issue. The objective of this research is to create a web log cleaning algorithm for web intrusion detection. Studies on previous works showed that there are five major web log attributes needed in web log cleaning algorithm for intrusion detection, namely multimedia files, web robots request, HTTP status code, HTTP method and other files. The enhanced algorithm is based on these five major web log attributes along with a set of rules and conditions. Our experiment shows that the proposed algorithm is able to clean noisy data effectively with a percentage of reduction of 40.41 and at the same time maintain the readiness for web intrusion detection at a low false negative rate (0.00531). Future works may address the web intrusion detection mechanism.
