Calculating the probability of detection and removal of threats to information security in data channels

Study is devoted to the calculation of the probability of detection and elimination of threats to the security of information in a computer system. It was a mathematical model to compute the probability in computing systems with any number of security elements. It was an example of the calculation of the probability for a computer system which includes three elements providing the information security of the system. Using multiple actions and means the protection of information in a computer system can increase the probability of detecting threats to information security.
