What is Operational Technology (OT)?
Operational technology (OT) means using hardware and software to monitor and control industrial equipment, physical processes, and devices. It is used in many industries, including manufacturing, energy, transportation, etc.
For example, a factory may use sensors and automated control systems to monitor the machines’ temperature, pressure, and speed on the assembly line. These systems help run everything properly and safely. Additionally, they allow for automatic adjustments when needed to alert workers in case of accidents and injuries.
Protect critical industrial systems with 24/7 monitoring, threat detection, and compliance-driven OT security.
Why is OT Cybersecurity Important?
Operational Technology (OT) systems control and monitor physical processes and environments. They are often found in critical infrastructure industries such as energy and utilities, transportation, and manufacturing. OT systems are often connected to the Internet or other networks, which opens them up to potential cyber threats.
If these systems are compromised, it could have severe consequences for the safety and operations of the facilities they control, even risk human life, for that matter. That’s why OT Cybersecurity is so critical.
Organizations need to take steps to secure their OT systems from cyber threats, just as they would any other type of information system. This includes things like patch management, access control, and network segregation.
OT systems often have unique characteristics that need to be considered when securing them. For example, they may be located in remote or hard-to-reach places, or they may need to be able to operate in conditions with no Internet connection. This can make traditional security measures like installing firewalls or antivirus software difficult or impossible.
Organizations must be aware of the risks posed to their OT systems and take steps to protect them. Cybersecurity is a critical part of any OT security strategy.
Challenges to OT Cybersecurity
There are many challenges to OT cybersecurity, such as the fact that these systems are often old and use outdated technologies. Additionally, OT systems are usually located in remote or difficult-to-access areas, making them difficult to protect.
OT cybersecurity is a complex challenge due to the variety of systems and devices that make up OT networks, the often-critical nature of these systems, and the fact that they are often not designed with security in mind. Additionally, OT systems are often connected to other systems and networks, making them difficult to isolate and protect.
The challenges to OT cybersecurity are significant with growing threats like ransomware and advanced persistent threats (APTs). But we can take some steps to mitigate the risks. These include increasing awareness and understanding of OT cybersecurity risks, implementing security controls and procedures, and using advanced threat detection technologies like AI and machine learning to monitor unusual activities in real-time and respond to incidents.
Despite the challenges, it is essential to protect OT systems from cyberattacks. One way to do this is to isolate OT systems from the rest of the network. It can help prevent attackers from gaining access to these systems. Additionally, we can monitor OT systems for signs of intrusion and should implement security controls to prevent and detect attacks.
Cyber Security Standards for OT
Many standards and best practices exist for securing industrial control systems and other Operational Technology (OT) assets. These include standards from the International Society of Automation (ISA), the National Institute of Standards and Technology (NIST), and the Center for Internet Security (CIS).
If you’re not sure which one to use, check out these standards:
- ISO/IEC 27032:2018 – The cybersecurity risk management and compliance standard. It provides guidelines for implementing a comprehensive cybersecurity program within an organization’s IT infrastructure and processes.
- ISO/IEC 27034:2018 – The standard defines principles, concepts, and requirements relating to information security management systems (ISMS). It also guides on implementing best practices when developing an ISMS.
- PCI DSS v3 – Ensures compliance with security standards for handling payment card data.
- The ISA/IEC 62443 series of standards is the most widely recognized set of standards for industrial cyber security. They provide a comprehensive framework for securing industrial control systems, from the device to the enterprise level.
- The NIST 800-82 guide provides best practices for securing industrial control systems, including guidelines for network architecture, device hardening, and security monitoring.
- The CIS Critical Controls for Effective Cyber Defense is a set of best practices for securing OT systems developed by a consortium of leading OT security experts.
- Integrating IT Governance – Embedding IT governance within business processes via enterprise architecture (EA) models.
- Risk Assessment – Applying risk assessment techniques throughout all phases of development cycles.
- Incident Response – Implementing effective incident response plans to address major incidents or disasters affecting organizations’ networks or assets, including those containing sensitive data (e.g., intellectual property).
These standards and best practices provide a solid foundation for securing OT systems against cyber threats. However, it is important to note that no single set of standards or practices can provide complete protection. Organizations should tailor their approach to OT security according to their specific needs and risks.

How to Secure OT Infrastructure?
There is no one-size-fits-all answer to the question of how to secure OT infrastructure. However, we can follow several best practices to help ensure the security of OT systems. These include:
- Establishing a clear and well-defined security policy for OT systems.
- Conducting regular risk assessments of OT systems and networks.
- Implementing security controls such as firewalls, intrusion detection/prevention systems, and access control measures.
- Monitoring OT systems and networks for suspicious activity.
- Training OT personnel in security awareness and best practices.
- Adopt a zero-trust model by verifying every user, device, and connection, assuming nothing is trusted.
- Increase OT security with locks, access cards, cameras, and biometrics for safe, authorized access.
By following these best practices, organizations can help to ensure the security of their OT systems and networks.
IT vs. OT Cybersecurity
The distinction between IT and OT Cybersecurity is becoming more and more blurred. IT and OT cybersecurity professionals must stay updated on the latest threats and vulnerabilities to protect their organizations.
However, there are some key differences between IT and OT Cybersecurity. OT cybersecurity focuses more on operational technology, such as industrial control systems and SCADA systems. These systems are often critical to the functioning of an organization, so OT cybersecurity professionals need to be aware of the unique threats and vulnerabilities associated with them.
OT cybersecurity prioritizes safety and system availability because downtime in OT systems can cause major financial losses or safety risks.
On the other hand, IT Cybersecurity is more focused on traditional information technology, such as computers, networks, and data storage systems. While these systems are also critical to the functioning of an organization, they are not typically mission-critical like OT systems.
IT Cybersecurity prioritizes data confidentiality, ensuring sensitive information is accessible only to authorized users. IT cybersecurity professionals mainly focus on protecting data and preventing unauthorized system access.
Both IT and OT Cybersecurity are important, and the distinction between them is becoming less and less important. However, understanding the key differences is essential for ensuring that your organization is properly protected.
Notable OT Cybersecurity Attacks
Many high-profile cybersecurity attacks have caused significant damage and disruption in recent years. These attacks have targeted various organizations, including government agencies, critical infrastructure operators, and large corporations. The attackers have used various methods, including malware, phishing, and denial-of-service (DoS) attacks.
One of the most notable attacks was the WannaCry ransomware attack, which occurred in May 2017. This attack used a piece of malware that encrypted the files on infected computers and demanded a ransom payment to decrypt them. The WannaCry attack affected more than 200,000 computers in 150 countries and caused billions of dollars in damage.
Another notable attack was the NotPetya attack, which occurred in June 2017. This attack also used ransomware to encrypt files on infected computers. However, the NotPetya attack was designed to cause as much damage as possible and did not include a mechanism for decrypting the files. As a result, the NotPetya attack caused more than $10 billion in damage.
These attacks illustrate the serious threat cyberattacks pose to organizations of all types. Organizations must be vigilant in protecting their systems and data from these threats.
Why do CISOs require an OT Cybersecurity Program?
As a CISO, you’re responsible for making sure your company’s highly sensitive company data is secure from internal and external threats. How can you ensure sensitive data on your business-critical OT (operational technology) systems is protected?
