Analysis and Assessment of Risk in Digital Railway Radio Communication System

摘要

This paper presents an analysis of potential threats to information transmission in a GSM-R system, including technical factors, human factors and organizational factors. Modern telecommunications systems are exposed to a variety of hazards variable in time. In this paper, they are divided into three underlying groups: hardware and software related, intentional and unintentional as well as internal and external. The role of risk assessment in information security management is presented. Distinct phases of risk assessment process are characterized. Methods used in the process of risk assessment and risk planning are discussed, taking into account possible responses to threats and opportunities. Lastly, an original method for identifying threats and detecting vulnerabilities in railway radio communication systems is presented.
