Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Categorization of Critical Information Infrastructure Objects Using Security Passports M.YU. RYTOV, N.O. NUSIENKO, V.A. VORONIN Review of the safety data sheet for the fuel and energy complex and the safety data sheet for the hazardous facility and the subsequent assessment of the applicability of this information in the context of the procedure for categorizing CII facilities. The procedure for synchronizing information from the safety data sheet of a fuel and energy complex facility and a safety data sheet of a hazardous production facility provides members of the commission with the opportunity to operate only with the necessary indicators, excluding the waste of time and resources on the preparation and primary procedures for the information security audit of the categorization object. In the context of the general procedure for ensuring the information security of the CII facility, the developed safety data sheet not only expands the set of initial data for the commission, but also increases the efficiency in forming a basic set of measures when creating a security system for a significant object and developing organizational and administrative documentation.
