Understanding Operational Technology (OT) Cyber Security.

Operational Technology (OT) has become an integral part of our everyday lives. From controlling industrial processes to managing critical infrastructure, OT plays a key role in our society. However, with the rise of connectivity and automation, OT systems have become a prime target for cyberattacks. That’s where OT cyber security comes in. It’s an essential aspect of securing our world. But what exactly does it entail, and how can it be implemented effectively? Let’s have a closer look.

What is OT in Cyber Security?

Operational Technology (OT) refers to the hardware and software used to change, monitor or control physical devices, processes, and events in the enterprise. OT is primarily used in industrial control systems (ICS) like supervisory control and data acquisition (SCADA) systems, distributed control systems (DCS), and programmable logic controllers (PLCs).

OT cyber security, therefore, focuses on protecting these systems from cyber threats. It involves implementing security controls to mitigate vulnerabilities inherent in OT environments, such as those relating to remote access, malware, and hackers.

The Importance of OT Cyber Security

The merging of IT and OT systems, propelled by the Industrial Internet of Things (IIoT) and digital transformation efforts, has expanded the vulnerable areas for cyber attackers. This amalgamation, combined with the essential functions that OT systems fulfill, underscores the imperative for OT cybersecurity. 

Neglecting to sufficiently protect OT systems can result in dire consequences. For example, cyber-physical attacks have the potential to inflict catastrophic harm on vital infrastructure, resulting in shutdowns, disruptions, or even the loss of human life.

Enhancing OT Cyber Security: A Framework Approach

Implementing OT cyber security requires a comprehensive approach. An example of this can be seen in the utilization of a cybersecurity framework like the NIST Cybersecurity Framework, which furnishes directives for recognizing, safeguarding against, detecting, responding to, and recuperating from cyber threats. 

These frameworks prominently feature risk management as a pivotal element..It involves identifying and prioritizing vulnerabilities in OT systems, implementing security controls like access control and network segmentation, and continuously monitoring for cyber threats.

Additionally, adopting a zero trust approach, where no user or device is automatically trusted, can further enhance OT security. This can involve measures like strong authentication and real-time monitoring of network access.
