Planning of railway infrastructure development in combination with the construction of an integrated periodic train timetable

Cybersecurity has become an essential aspect of the modern world, and its importance extends to various sectors, including railway transport. Particularly noteworthy is cybersecurity in systems and products that directly impact rail traffic safety. For such solutions, it is necessary to develop a common approach to cybersecurity management to ensure adequate resistance of the product to intentional or unintentional attacks from the outside, covering all stages of the product's cycle. The article focuses on presenting the issue of cybersecurity in the railway sector, presents the differences in the understanding of functional safety and cybersecurity, discusses the technical standard defining the process of cybersecurity management during the life of railway products, and presents the process of cybersecurity risk analysis proposed in this technical standard. Moreover, it is worth noting that the article presents the author's methodology for determining the SL-T vector. In addition, the article presents the author's methodology for determining the SL-T vector.
