Abctract. Considered the problems information space navigation and the ship, as the object of informationsecurity waterways. Formed the category of information flows for modeling their interactions in order to prioritizethe information space navigation. Investigated priority flows ship information in a continuous exchange ofinformation, allowing to increase the safety of navigation. Shows an embodiment of methods of surgical analysis ofthe information space and its application in the formation of information impacts on the management of the vessel.Using matrix and Graphology analysis carried out studies of information flow in the navigation. Justified the priorityobjective and focus of the proposed method. Shows a computer visualization prioritization of information flows.Results of the study the information space will create the information - analytical system for the provision of servicesto ships under continuous threats and risks.Keywords: waterway, navigation, information flows, information security, information space model,graph, matrix state priority.
