Presenting a pattern for detection of denial of service attacks with web mining technique and fuzzy logic approach

Hackers attack a server of website collectively. In other words, DOS attacks have been sent by hackers into server. To identify DOS, an accurate approach is required. Such attacks can be detected by analyzing Log File of server. In this paper, attempt has been made to present a model by combining web mining technique with fuzzy logic approach to evaluate probability of DOS attacks using two effective factors of the number of Hits and time interval of the requests so that appropriate preventive measures can be taken under different conditions.
