Abstract: Purpose: The purpose of this chapter is to introduce the reader to the theory and practice of cybersecurity, the main understanding of cybersecurity, the challenges faced globally, the security principles, and the security models for protecting the information security chain from various threats. In the second part of the chapter, we will introduce the critical aspects of the robust cybersecurity model, which was developed within the framework of the UPBAL project "Be Secure" and which gained further development in the F182 project on smart grid security.
Design/methodology/approach: The theoretical part of the chapter is based on the General Systems Theory, on which the main understanding of cybersecurity appears, while the current results are based on the experience achieved within the framework of the two mentioned projects, evaluated in the Piloting Reports, and theoretical strategies of other cyber defense-related theories. The theoretical principles are illustrated by several real-life practical examples from the field of ICT security.
Findings: As it is quite difficult to find any wider theories and practical documents that are oriented only to the needs of the development of the principles of a concrete area of cybersecurity, the concepts and strategic steps proposed could be of potential use to researchers and experts in this field, to discover the importance of developing a wider cybersecurity theory, find approaches within generalized methodology, as well as study and apply already developed criteria aspects and principles.
