Комбинирование механизмов защиты от сканирования в компьютерных сетях

Комбинирование механизмов защиты от сканирования в компьютерных сетях

Abstract

Предлагается подход к комбинированию различных механизмов обнаружения сетевого сканирования в компьютерных сетях, который позволяет существенно повысить эффективность обнаружения за счет уменьшения количества ложных срабатываний и повышения точности обнаружения сканирования. Дается представление об отдельных частных методиках обнаружения сканирования. Рассматриваются основные принципы их комбинирования, а также дополнительные архитектурные улучшения общей модели обнаружения сканирования. Предлагается подход к автоматической настройке параметров используемых механизмов на основе статистических данных об анализируемом трафике.

An approach to combine different mechanisms of net19ork scanning detection in computer net19orks is proposed. The approach allo19s to highly improve the detection effectiveness due to reduction of the false positive rate and increase in the scanning detection accuracy. Some particular scanning techniques are outlined. The core combining principles and architectural enhancements of the common scanning detection model are considered. An approach to automatically adjust the parameters of employed mechanisms based on statistical data about net19ork traffic is also suggested.
