Made reasoning of the information protection from leakage through technical channels for uneven distribution of source probabilities and set the negative sequences in case of its non-consideration.Shown relations of probability information security risk conditions with power at the input of intercept receiver and given requires analytical values, which allow to assess the risk relative to the current signal/noise ratio and for the given probability of the safety risk of the required values of the maximum allowable indicators, namely the throughput of the technical channel of leakage, the probability of correct reception with possible interception and the signal/noise ratio.These ratios differ from previously known by those that take into account the uneven distribution of the signs probability on output of the source of leakage.Ratios allow automated analysis of information security risk in real time with the use of modern information systems and technologies.
