What is OT security?

OT Security (Operational Technology & Security) It refers to hardware and software that are used to physical devices and to manage, monitor and control processes in the industry against cyber attacks and other threats. This includes systems such as:

  • Production lines in factories.
  • Energy supply, such as power networks and windmills.
  • Transport, for example traffic management systems or railway control.
  • Water management, such as drinking water treatment or irrigation.

Because many OT systems are designed without regard to cyber threats, it is essential to protect them against malicious attacks that can damage critical infrastructures.

How does OT Security work?

OT Security is about protecting the systems that power operational technologies. It's a multi-dimensional approach that offers different layers of protection:

  • Network segmentation: OT networks are separated from IT networks to prevent an attack on an IT system from spreading to OT systems.
  • Access control: Only authorized employees can access critical systems. The use of strong passwords, multi-factor authentication, and role-based access control is essential.
  • Real-time monitoring: Monitoring systems and networks in real time helps to quickly detect suspicious activities or anomalies, so that action can be taken quickly.
  • Software updates: Regularly updating systems and software is essential to close security gaps and ensure the latest security patches. You can keep track of this by means of Managed Security Services.

How does OT differ from IT?

Although IT (Information Technology) and OT (Operational Technology) are often confused, they fulfill different roles in an organization. While IT focuses on digital information and communication, OT focuses on the physical processes and machines that are essential to the operation of the industry. Here is a brief overview of the main differences:

  • IT (Information Technology) focuses on data processing and digital communication. It includes systems such as servers, databases, and networks that manage, process, and share information.
  • OT (Operational Technology) is about managing physical processes and machines. It includes systems that are used to control and control industrial processes such as production, energy supply and transport.

In short: IT is about data and communication, while OT focuses on the operation of physical systems and machines.

The biggest threats to OT systems

OT systems are increasingly being targeted by cybercriminals. The biggest threats to OT security include:

  • Ransomware: Cybercriminals encrypt data or block access to critical systems and demand a ransom for its release. This can completely shut down the operation of a factory or energy system.
  • Phishing attacks: These attacks attempt to trick employees into revealing sensitive information or installing malicious software that provides access to OT systems.
  • DDoS attacks: Distributed denial-of-service attacks can overload OT systems and disrupt access to critical infrastructures.
  • Sabotage: Malicious parties can try to cause physical damage, for example by disrupting processes or disabling systems.

The importance of OT Security

OT systems are the backbone of essential infrastructure, from power networks to water treatment plants. The impact of a successful cyber attack can be serious. For example:

  • Shutdown of production processes: This can result in financial losses due to delayed productions or damage to equipment.
  • Safety risks: In sectors such as health care or energy, disruptions can lead to dangerous situations for employees and society.
  • Loss of confidentiality: The leak of data can not only be financially harmful, but also undermine the trust of customers and partners.

The Future of OT Security

The future of OT Security will be strongly influenced by new technologies, such as AI, machine learning, and the Internet of Things (IoT). These technologies offer new opportunities for both protection and attacks. Companies need to prepare for an increasingly complex threat landscape and invest in robust OT security strategies that are flexible enough to adapt to future challenges.

Checklist: Is your OT infrastructure secure?

Check the security of your OT systems with this simple checklist:

  1. Are your OT systems separate from IT networks?
  2. Is access to systems restricted to authorized personnel?
  3. Are security patches applied regularly?
  4. Is there 24/7 monitoring and real-time threat detection?
  5. Does your team have an incident response plan in case of an attack?
