in information and communication technologies, force us to keep most of the information electronically, consequently, the security of information has become a fundamental issue. The traditional intrusion detection systems look for unusual or suspicious activity, such as patterns of network traffic that are likely indicators of unauthorized activity.(More)
It is an important issue for the security of network to detect new intrusion attack and also to increase the detection rates and reduce false positive rates in Intrusion Detection System (IDS). Anomaly intrusion detection focuses on modeling normal behaviors and identifying significant deviations, which could be novel attacks. The normal and the suspicious(More)
—Discovering user access patterns from web access log is increasing the importance of information to build up adaptive web server according to the individual user's behavior. The variety of user behaviors on accessing information also grows, which has a great impact on the network utilization. In this paper, we present a rough set clustering to cluster web(More)
Web Usage Mining is that area of Web Mining which deals with the extraction of interesting knowledge from logging information produced by Web servers. A challenge in web classification is how to deal with the high dimensionality of the feature space. In this paper we present Independent Component Analysis (ICA) for feature selection and using Rough Fuzzy(More)
Grid computing is the principle in utilizing and sharing large-scale resources to solve the complex scientific problem. Under this principle, Grid environment has problems in providing flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources. However, the major problem is in optimal job scheduling,(More)
