Method on rule extracting in misuse intrusion detection based on rough set genetic algorithm

An integrated method that combines rough set theory and genetic algorithm for rule Extracting is present. It takes full advantages of rough set theory and genetic algorithm. Reduction is done firstly on the basis of rough set theory that is good at processing redundant and inconsistent data. Then genetic algorithm is used to mine rules. Using such a method, simple and reasonable rules can be deduced. The operation procedure is illustrated by an example, and the results show that the algorithm is effective and feasible when applying it to misuse intrusion detection for rule acquisition.
