The paper presents a method to increase trust levels of foreign and domestic-made hardwaresoftware platforms, designed to build specialised devices and computing facilities, which are meeting safety requirements and protected from BIOS vulnerabilities, to work with classified information. The purpose of the study is to investigate the ability of designing trusted foreign and domestic-made hardware-software platforms, protected from exploiting BIOS vulnerabilities. Research methods: in order to choose PC module that will be used for designing trusted hardware-software platform an analysis of Russian industrial-grade PC modules was made. In addition an analysis of known BIOS vulnerabilities was made. Proprietary BIOS replacement in a form of domestic-made Horizon bootloader, which includes unauthorised access to information protection measures was made as well as a possibility of practical use of trusted hardware-software platform with Horizon bootloader was overviewed. Obtained result: PC module for trusted hardware-software platform was selected, proprietary BIOS replacement in a form of domestic-made Horizon bootloader, which includes unauthorized access to information protection measures, was made; an increase in the level of trust levels of foreign and domestic-made hardware-software platforms, which are used to create specialized devices and computing facilities while meeting safety requirements and protected from BIOS vulnerabilities to work with classified information has been ensured; an approach to create trusted hardware-software platform design requirements and conditions was proposed; needs to exclude potentially dangerous Intel Management Engine controller's functionality were justified and proposal to use trusted hardware-software platform with Horizon bootloader was justified.

in this publicaton, a technique to increase trust levels of foreign and domestic-made hardware-software platforms, which are used to create specialised devices and computing facilities, which are meeting safety requirements and protected from BIOS vulnerabilities, to work with classified information, was made. Problems, which developer might encounter, were listed; methods of troubleshooting were proposed, and conclusions were made. The purpose of research is to investigate an ability of designing trusted foreign and domestic-made hardwaresoftware platforms, protected from exploiting BIOS vulnerabilities. Research methods: in order to achieve the purpose of research, an analysis of Russian’s industrial-grade PC modules was made in order to choose PC module that will be used for designing trusted hardware-software platform, an analysis of known BIOS vulnerabilities was made; proprietary BIOS replacement in a form of domestic-made Horizon bootloader, which includes unauthorised access to information protection measures, was made and possibilty of practical use of trusted hardware-software platform with Horizon bootloader was overviewed. Obtained result: PC module for trusted hardware-software platform was selected, proprietary BIOS replacement in a form of domestic-made Horizon bootloader, which includes unauthorized access to information protection measures, was made; technique to increase trust levels of foreign and domestic-made hardware-software platforms, which are used to create specialized devices and computing facilities, which are meeting safety requirements and protected from BIOS vulnerabilities, to work with classified information, was made; an approach to create trusted hardware-software platform design requirements and conditions was made; needs to exclude potentially dangerous Intel Management Engine controller’s functionality were justified and proposal to use trusted hardware-software platform with Horizon bootloader was made.
