Методика формирования и пополнения базиса типовых ситуаций в системах поддержки принятия решений по обеспечению информационной безопасности

Abstract

The presented article concerns the methodology of forming the standard situation basis in decision support system to provide information security based on the principle of separability. It is suggested to relate the present situation to one of the typical classes on the basis of uncertain close relationship between them. It is stated that the classification of situations on the principle of close represents a mathematical resolution of feature vector on some feature space basis. It is suggested to use algebraic procedure of feature vector resolution for similar situations providing a better approximation to the reference sets in the sense of the least square deviation. The suggested methodology of forming and replenishment of the typical situation basis will help to effectively fulfill decision analysis and learn decision-maker’s experience.

Данная работа посвящена разработке методики формирования и пополнения базиса типовых ситуаций систем поддержки принятия решений по обеспечению информационной безопасности, основанной на принципе отделимости. Предложено отнесение текущей ситуации к одному из типовых классов на основе нечеткого отношения сходства между ними. Показано, что классификация ситуаций по сходству представляет собой математическое разложение вектора признаков по некоторому базису признакового пространства. Предложена алгебраическая процедура разложения векторов-признаков для сходных ситуаций, обеспечивающая наилучшее приближение к эталонным наборам в смысле наименьших квадратов отклонений. Предложенная методика формирования и пополнения базиса типовых ситуаций позволит эффективно осуществлять анализ решений и усваивать опыт ЛПР по принятию решений.
