To maintain the security of the VSP from the leakage of information through the optical channel during operation at a given level, it is necessary to monitor its most important parameters that affect safety. These parameters include FSTEC of Russia, 2012: the maximum allowable change in transmission coefficient, reverse losses on local fiber defects, direct losses on local fiber defects, reaction time, average power of information signals at the input pole of the line. In this article, we analyzed and analyzed several methods for monitoring the security of fiber-optic transmission systems (VSP), namely: monitoring the parameters of fiber-optic lines, monitoring the response to various signals and monitoring the probability of detection of the violation.
