<strong>Security</strong> <strong>for</strong> <strong>Railways</strong> <strong>and</strong> <strong>Metros</strong><strong>Security</strong> Management System<strong>Railways</strong> <strong>and</strong> <strong>Metros</strong> worldwide share a set ofcharacteristics that make them very vulnerable to possibleattacks, from simple v<strong>and</strong>alism to terrorism. Thosecharacteristics are:• High volume of passengers• Openness <strong>and</strong> accessibility• Underground environments• Valuable assets distributed in remote sites• Multiple stakeholdersToday, the most critical challenge <strong>for</strong> world-class railways<strong>and</strong> metros is enhancing their level of security, whilekeeping their attributes of openness, extensiveness,accessibility, <strong>and</strong> af<strong>for</strong>dability.The concept of <strong>Security</strong> <strong>for</strong> <strong>Railways</strong> <strong>and</strong> <strong>Metros</strong> may bedefined as monitoring <strong>and</strong> protecting the infrastructure(stations, tunnels, rolling stock, bridges, viaducts, depots,yards, etc), <strong>and</strong> the users against:• Aggressions <strong>and</strong> antisocial behaviors• Thefts, v<strong>and</strong>alism <strong>and</strong> graffitism• Sabotage <strong>and</strong> terrorism• Unauthorized access to restricted areas<strong>Security</strong> Goals: Protect, Prevent, Preserve• Ensure the security of passengers at stations <strong>and</strong> onboard trains• Ensure the security of personnel• Protect critical assets• Protect the signaling <strong>and</strong> traffic control systems (IT <strong>and</strong>Telecoms)• Safeguard continuous operabilityWhile security can never be absolute, a security systemhas a very effective preventive, reassuring <strong>and</strong> deterrentfunction: a station will be less subject to possible threatsif it appears as a more secure place.<strong>Security</strong> Management System is an intelligent softwareapplication allowing <strong>for</strong> the review, analysis, control,comm<strong>and</strong> <strong>and</strong> follow up of all security installations in onesingle, user-friendly interface.It is the core application of any Railway or Metro <strong>Security</strong>system made by <strong>Ansaldo</strong> <strong>STS</strong>.It is designed as a fully integrated control/comm<strong>and</strong>center where relevant events detected by the local/peripheral subsystems are received <strong>and</strong> managed by theoperators.<strong>Ansaldo</strong> <strong>STS</strong> <strong>Security</strong> Concept<strong>Ansaldo</strong> <strong>STS</strong> follows a holistic approach to security in rail-based transportation which is made up of three main buildingblocks:• Risk Analysis• <strong>Security</strong> Management System• Design <strong>and</strong> Integration of monitoring subsystemsRisk AnalysisAn in-depth activity of Risk Analysis of the infrastructure tobe protected (from a station to a complete railway or metroline including depots <strong>and</strong>/or yards) is necessary in orderto evaluate the possible threats <strong>and</strong> to plan the mostsuitable measures <strong>and</strong> actions to reduce the risks. Theconcept of risk is represented by the combination of threemain factors: threats <strong>and</strong> their expected frequency, systemvulnerability with respect to the threats, <strong>and</strong> expectedconsequences of the threats.A Risk Assessment, per<strong>for</strong>med after a field inspectionthrough site surveys, is aimed at the identification of thesignificant attack scenarios <strong>and</strong> their related risk indexes.Risk Management, as a second step, is aimed atevaluating the impact, in terms of risk reduction, of thedifferent protection solutions.These activities may be complemented at a later stagewith full educational training of employees workingdirectly in the system because it is those in touch withthe everyday reality of a transportation infrastructure thatare capable of identifying be<strong>for</strong>e anyone else the possiblesigns of an atypical situation.SMS supplies to operators only the in<strong>for</strong>mation relevantto activated “real” threats, minimizing the risk of falsealarms <strong>and</strong> there<strong>for</strong>e optimizing security resources <strong>and</strong>Response Time of countermeasures. It also suppliesthe related emergency procedures, as agreed with theclient or as per best market practices, <strong>and</strong> allows <strong>for</strong> thevisualization of both the video streams associated with thealarms (automatically selected) <strong>and</strong> the ones selected bythe operator.At a glance, the main advantages of SMS are:• Shared, hierarchical <strong>and</strong> multi level architecture• <strong>Security</strong> management per<strong>for</strong>med• “Rules engines” usedat local level <strong>for</strong> the integration ofsecurity subsystems• Integration with security subsystems already in place &train control solutions• Animated graphical maps <strong>for</strong> alarmed sensors /cameras• Intelligent <strong>and</strong> easy to use operators tools• Event (alarms <strong>and</strong> user actions) reports• Emergency management with step-by-step operationsmonitoring• Tailored specifically <strong>for</strong> railways <strong>and</strong> mass transit2 3
