Railway applications - Cybersecurity
This document provides to the railway operators, system integrators and product suppliers, with guidance and specifications on how cybersecurity will be managed in the context of the EN 50126-1 RAMS lifecycle process. This document aims at the implementation of a consistent approach to the management of the security of the railway systems. This document can also be applied to the security assurance of systems and components/equipment developed independently of EN 50126.
This document applies to Communications, Signalling and Processing domain, to Rolling Stock and to Fixed Installations domains. It provides references to models and concepts from which requirements and recommendations can be derived and that are suitable to ensure that the residual risk from security threats is identified, supervised and managed to an acceptable level by the railway system duty holder. It presents the underlying security assumptions in a structured manner.
This document does not address functional safety requirements for railway systems but rather additional requirements arising from threats and related security vulnerabilities and for which specific measures and activities need to be taken and managed throughout the lifecycle. The aim of this technical specification is to ensure that the RAMS characteristics of railway systems / subsystems / equipment cannot be reduced, lost or compromised in the case of intentional attacks.
The security models, the concepts and the risk assessment process described in this document are based on or derived from IEC 62443 series standards. In particular, this document is consistent with the application of security management requirements contained within the IEC 62443-2-1 and which are based on EN ISO 27001 and EN ISO 27002

Železniške naprave - Kibernetska varnost
Ta dokument podaja smernice in specifikacije za upravljavce železniških naprav, integratorje sistemov in dobavitelje izdelkov v zvezi z upravljanjem kibernetske varnosti v kontekstu procesa življenjskega cikla RAMS iz standarda EN 50126-1. Cilj tega dokumenta je uvedba doslednega pristopa k upravljanju varnosti železniških sistemov. Uporabiti ga je mogoče tudi za zagotavljanje varnosti sistemov, komponent in opreme, razvitih neodvisno od standarda EN 50126.
Ta dokument se uporablja za komunikacijo, signaliziranje in obdelavo signalov, železniška vozna sredstva ter fiksne postroje. Vsebuje sklice na modele in koncepte, iz katerih je mogoče izpeljati zahteve oziroma priporočila in ki so primerni za zagotovitev, da oseba, ki je odgovorna za železniški sistem, zmore ustrezno prepoznati, nadzirati in upravljati preostalo tveganje zaradi varnostnih groženj. Osnovne varnostne predpostavke so v tem dokumentu strukturirano predstavljene.
Ta dokument ne obravnava zahtev glede funkcionalne varnosti za železniške sisteme, temveč dodatne zahteve, ki izhajajo iz varnostnih groženj in povezanih ranljivosti ter za katere je treba sprejeti posebne ukrepe in dejavnosti ter jih upravljati skozi celoten življenjski cikel. Namen te tehnične specifikacije je zagotoviti, da značilnosti RAMS železniških sistemov, podsistemov in opreme v primeru namernih napadov ni mogoče zmanjšati, izgubiti ali ogroziti.
Modeli varnosti, koncepti in postopek ocenjevanja tveganja, opisani v tem dokumentu, temeljijo na skupini standardov IEC 62443 oziroma iz nje izhajajo. Ta dokument je zlasti skladen z uporabo zahtev za upravljanje varnosti, ki jih vsebuje standard IEC 62443-2-1 ter ki temeljijo na standardih EN ISO 27001 in EN ISO 27002.
