The article considers an approach to increasing the security of computer systems from intrusion. The importance of the problem of information security and cybersecurity is substantiated. Strategies of attack and destructive actions used by intruders (hackers) are considered. 16 different attack and intrusion strategies are identified.
The reasons for the vulnerability of computer systems are analyzed. Two groups of reasons are considered: objective reasons depending on the hardware and software components of the computer system and subjective reasons depending on the human factor. It is noted that one of the main reasons that objectively complicate the protection of a computer from intrusion is that the same computer is assigned the solution of two unrelated problems: the direct solution of tasks, which are essentially an internal problem, and the tasks of communication, which can be seen as an external problem.
An approach is proposed to increase the security of computer systems from intrusion through hardware redundancy, in particular, instead of one computer, use a computer unit consisting of two computers – internal and external. The internal computer is used for the direct solution of tasks. The external computer is responsible for performing communication tasks. Additionally, the issues of physical protection of computer systems are considered.
