Computer intrusion detection method using fuzzy set

摘要

The present invention relates to a computer intrusion detection method, the statistical processing unit of the conventional intrusion detection system only has a simple statistical data such as frequency, average, variance, so that when determining the intruder to solve the problem that is difficult to estimate the intruder By applying fuzzy set to the statistical method of numerically, the user's real-time recognition is possible by numerically clearly calculating the abnormal user's behavior by statistics. In particular, the application of fuzzy set enables the characteristics of general users with standard normal distribution. Since the weight of abnormal user statistics can be weighted, a computer intrusion detection method using a fuzzy set that provides reliable inference of the statistical processing unit of an illegal computer intruder is proposed.
