Представлен метод моделирования угрозы безопасности информационной системы с использованием аппроксимирующих функций, получаемых с помощью построенной укрупненной марковской модели угрозы атаки. Информационная система рассматривается как система с отказами и восстановлениями характеристики безопасности. Предлагаемый метод позволяет получать принципиально новые и крайне важные для проектирования систем защиты характеристики безопасности информационных систем.
Informational system security threat modeling method is developed using approximating functions designed on the base of pre-built Markov model of attack threat. The information system is considered as a system with failures and restorations of security characteristic function. The proposed method allows deriving principally new and important informational system security characteristics to be used in security system design.
