Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Recognition of negative external actions on the network information system AL BALUSHI M. GRECHUSHKINA A.Y. DIDRIKH V.E. ZAITSEV D.V. Operation is devoted a problem of a choice of aspects of means of parrying of external actions, operating on a network information system so that stability of functioning last was maximum. In operation settings and algorithms of a solution of two tasks of search of negative external actions on elements of the network information system, maximising function value of a damage are offered. Keywords: a network information system, negative external actions, probability. Contacts: E-mail: docdcmdvv@mail.ru Pp. 50-54.
