• Hackers yet again targeted the Ukrainian railway company Ukrzaliznytsia in 2020 and disrupted its passenger information system.

These are just a few examples of the many cyberattacks that have taken place against railways in recent years. The increasing frequency and severity of these attacks highlight the importance of cyber security in the railway industry.

In summary, a cyberattack on railways can have serious consequences, including disruption of train services, theft of sensitive data, tampering with safety systems, or even causing accidents. Let us take a closer look at the mitigation measures in the sections below.

Protecting the rail network from cyber threats

Cybersecurity is essential to safeguarding the rail modernization mission. As railways become more reliant on technology, they also become more vulnerable to cyberattacks. A successful cyberattack on a railway could have catastrophic consequences, causing delays, disruptions, and even accidents. Here are some of the mitigation measures to protect against cybersecurity challenges:

Ensuring data and connected systems are protected

One of the key roles of cybersecurity in the railway sector is to ensure that data and connected systems are protected. This includes:

• Implementing strong authentication and authorization measures to protect access to data and systems.
• Encrypting data at rest and in transit.
• Segmenting networks to isolate critical systems from the internet and other networks.
• Deploying security solutions to detect and prevent cyberattacks.
• Monitoring systems and networks for suspicious activity.

Governance, Risk, and Compliance

Cybersecurity governance, risk, and compliance (GRC) is a framework for managing cybersecurity risks and ensuring compliance with regulations. GRC includes the following components:

• Governance: The governance component of GRC defines the roles and responsibilities for cybersecurity within the organization. It also establishes the policies and procedures that must be followed to protect data and systems.
• Risk management: The risk management component of GRC identifies and assesses cybersecurity risks. It also develops and implements plans to mitigate those risks.
• Compliance: The compliance component of GRC ensures that the organization complies with all applicable cybersecurity regulations.

Adherence to standards like ISO 27001, ‎TS50701, and‎ IEC 62443

ISO 27001, TS50701, and IEC 62443 are international standards that provide guidance on cybersecurity best practices.

• ISO 27001 is a generic information security standard that can be applied to any organization. It provides a framework for managing information security risks and protecting data and systems.
• TS50701 is a railway-specific information security standard. It is based on ISO 27001 and includes additional requirements for railway cybersecurity.
• IEC 62443 is a set of standards that provide guidance on cybersecurity for industrial control systems. This includes railway signalling and control systems.

Railways can use these standards to develop and implement their cybersecurity programs.
