    Cyber Security services for Railway systems and OT Security management

    Security is becoming a priority in industrial IT and Operational Technology (OT) as connectivity to external networks grow and attacks on operational technology increase. Many companies are still not aware of the threats that cyberattacks pose to their OT assets. Moreover, their measures for cybersecurity are usually not tailored to operational technology. Such considerations for critical infrastructure such as railway environment are today regulated based on new EU/UN directives (e.g. NIS) and national rules. In that context, ISA/IEC 62443 standard series, with its railway-oriented specification CEN CLS TS 50701 represent the State-of-the-Art.

    CertX Cyber Security team supports industrial actors based on following services: 

    • Awareness & Education
      • Increasing awareness and understanding about best IT/OT security practices throughout introduction courses, or deep-dive sessions on specific methods, e.g. cyber threat analysis and risk assessment
    • Compliance check & certifications for evaluating your current management system practices, processes and product capabilities, and validate them according to ISA/IEC 62443, CEN, CLC TS 50701, ISO/IEC 15408 (Common Criteria), or any other related reference document.
    • Technical evaluation & Testing for challenging your products and/or infrastructure against attack attempts
    • Supporting services for accompanying your team on the right path for implementing best security practices and complying with State-of-the-Art references.
