The article provides a comparative analysis of certain types of operational-search measures related to obtaining information from the means of its processing and storage. The following types of operational search activities carried out in the information and telecommunication Internet network are analyzed: “surveillance”; “removal of information from technical communication channels”; “getting computer information.” Considered changes in legislation in this area and the legal basis of the operational-search event “Obtaining computer information”. The implementation of the first two types of operational-search measures, in part or in whole, can be replaced by a new type of operational-search measures. Analyzed the regulatory framework of individual operational-search activities. The basic concepts and terms in the field of building data transmission channels are considered: hosting provider, information owner, website owner on the Internet, communication channel, node of the secondary network, information, computer information, computer, computer concept. The basic reference model of open systems interaction is also considered. It consists of seven interaction levels: application layer, presentation layer, session layer, transport layer, network layer, channel and physical layer. Submitted technical means corresponding to each of the levels. The types of information obtained at each level are considered. Two groups of means for obtaining computer information are proposed: means of remote access to a computer system and means of physical access to a computer system or electronic information carrier. A general characteristic of the substantive part of the operational-search event “obtaining computer information” is proposed.

Keywords: : getting computer-data, operatively-search activity, Internet, technical communication, network operator, hosting provider.
