Abstract:
|
The variety and complexity of virus harm cause there is few practical evaluation methods currently. The paper first presents harms? definition and classification of the virus. Then representative first-level and second-level evaluation indexes are proposed. However, as these evaluation factors could hardly be assigned with definite values and somewhat have fuzziness, the paper constructs a fuzzy evaluation model for the harm of computer virus. Once an obscure value is assigned to each evaluation indexes in the second level, the model can calculate the membership degree to each of the five harm grades, and then obtains a reasonable harm evaluation result. Finally, the paper evaluates the harms of ?Worm.WhBoy.h?, ?AutoRun?, ?JS.Yamanner.a? and ?An-ti-virus? by the fuzzy model; the evaluation result is similar to the statistics of the virus.
