Abstract

The chapter is organized as follows: In section 1, the basic definitions of the security risk analysis and the characteristics of the railway security problem are introduced, and a bibliography review is reported. Then, in section 2, the general architecture for designing a security risk analysis tool is presented, focusing on the relevant specifications, and on the input/output characteristics. Therefore, in section 3, with the aim of pointing out the characteristics of the presented architecture, an explicative case study is defined based on real world data coming from Italian railways. Finally, some conclusions and remarks are discussed in chapter 4.

Definitions, Motivations And Bibliography Review On Railway Security

In this section a basic glossary of the terms used in the chapter is provided, and the basic characteristics that make railway systems of significant interest for security are discussed. In the end, a bibliography review is presented.

Basic Glossary

In this section, a brief glossary of the most common terms used in the chapter is provided with the aim of facilitating the comprehension of the following sections. Then, consider the following basic definitions:

  • Threat: The potential intent to cause harm or damage to properties or people;

  • Attack Likelihood: An estimate of the real probability/frequency of a real attack

  • Terrorism: A deliberate use of violence against people or properties with the aim of intimidating or coercing a government, the civilian population in furtherance of political or social objectives;

  • Sabotage: A deliberate action aimed at weakening an enemy through subversion, obstruction, disruption, and/or destruction. Unlike terrorists, saboteurs do not consider fatalities the primary objective, although they do not exclude them;

  • Robbery/Theft: The use of force or violence against properties or people with the aim of depriving the rightful owner of property;

  • Vandalism: The use of force or violence against property with intent of malicious destruction of defacement of public or private property;

  • Adversary: A general term indicating terrorists, saboteurs, thieves and vandals;

  • Attractiveness: A measure of the likelihood of an attack to an asset;

  • Vulnerability: A measure of the easiness of a security protection system to be overcome by adversaries.

The interested reader may refer to ASIS International (2003) and Garcia M. L. (2001) for a more complete glossary.
