Artificial Intelligence has been booming in recent years and is already a reality today that is transforming multiple aspects of our society and industry.

In the face of this, industrial cybersecurity was not going to be left behind, and this paradigm shift forces to rethink different strategies and security measures in order to adapt to the new needs and threats that arise.

In this article, we explore the role of Artificial Intelligence, its application and impact in the field of industrial cybersecurity, highlighting how InprOTech GUARDIAN implements this technology to stay at the forefront in the protection of industrial infrastructures.

What is Artificial Intelligence?

Most people have heard of Artificial Intelligence, but not everyone understands what it is and how it works. AI can be defined as the ability of computer systems to perform tasks that mainly require human intelligence, learning, reasoning, recognising patterns, making decisions, etc.

Its operation is based on Machine Learning algorithms, which process large volumes of data and information, using different and sophisticated mathematical techniques to identify patterns, from which it will make predictions. This process is known as training, where the algorithm iteratively adjusts parameters, learning from errors and improving accuracy.

This generates what is known as the Model, which is finally applied to new data, detecting anomalies and predicting behaviour.

There are several types of Artificial Intelligence and their applications in cybersecurity vary:

General purpose AI: Used for language processing, data analysis and task automation. Widely known models such as Chat-GPT, Gemini or Copilot.

Specialised AI: Algorithms designed for specific tasks, traffic patterns, image analysis, voice recognition, etc.

Impacto f AI on OT cybersecurity

As mentioned above, Artificial Intelligence is here to stay, and this has had a major impact on the field of cybersecurity.

This technology is a double-edged sword that forces us to rethink traditional security strategies and measures. On the one hand, the use of AI has democratised cyberattacks and improved their efficiency and effectiveness, opening up new vectors and attack surfaces. On the other hand, and on the other hand, it also represents a powerful defence tool, capable of improving threat detection, anticipating behaviour and increasing cybersecurity. In this sense, AI becomes the best ally to combat the dark side of its own use.

AI applications in OT cybersecurity

Some of the main applications and benefits of AI in industrial cyber security are:

Threat detection and response: AI can analyse large volumes of data to identify anomalous patterns of behaviour, helping to detect threats that might go unnoticed. In addition, machine learning helps anticipate and prevent cyber-attacks, improving response times, reducing risk and acting proactively.

Risk prediction and management: AI algorithms can predict attack risks and recommend actions to mitigate them before they occur. They also help identify and correct vulnerabilities in OT infrastructures before they are exploited.

Incident response automation: AI can automate incident response, isolating systems, patching quickly, minimising risk and freeing up workload, allowing security analysts to focus on more complex tasks.

Monitoring and optimisation of industrial processes: AI algorithms have the ability to predict maintenance needs, which can prevent future equipment problems that would lead to unscheduled production downtime.

As threats evolve and industrial environments become more complex, Artificial Intelligence is positioned as a key component of OT cyber security, both now and in the future.

Challenges of AI in OT Cybersecurity

As previously mentioned, Artificial Intelligence represents a double-edged sword, which makes it both a threat and a challenge, not only in terms of malicious use, but also in terms of misuse or misuse. Some of the main challenges are:

New vectors and attack surfaces: The most obvious challenge is the malicious use of this technology, as it can help execute cyber attacks more effectively and more efficiently, making it necessary to be prepared.
Model quality: Models are directly dependent on the data on which they are trained. If the data is incomplete, biased or unrepresentative, the model will be ineffective. Ensuring data quality can be difficult due to industry-specific privacy, security and availability constraints.
False positives/negatives: This can be one of the main consequences of the previous point, and it is necessary to ensure the effectiveness of alerts, avoiding false positives that lead to saturation or, on the contrary, lack of detection due to false negatives. Maintaining a balance between sensitivity and accuracy is a key technical challenge.
Qualified personal: The implementation, management and continuous improvement of AI-based solutions requires personnel with advanced skills in cybersecurity, data and artificial intelligence. The shortage of professionals with this profile represents a barrier for many industrial organisations.
Difficult interpretation and integration: Integrating AI solutions into OT infrastructures is not a trivial task. Industrial environments often have legacy systems, sensitive configurations and technical limitations that make it difficult to adopt new technologies.

While Artificial Intelligence offers great advantages for strengthening cyber security in OT environments, its implementation presents challenges. Overcoming these challenges will be key to secure, effective and sustainable adoption

InprOTech Guardian

InprOTech Guardian is a cybersecurity technology specifically designed and developed to protect industrial networks. Among its main objectives (in addition to generating an inventory of OT and wireless devices), it monitors the traffic generated in production environments and analyses it based on a combination of static rules, an IDS and artificial intelligence and honeypots, allowing it to learn from the behaviour of the network, detect anomalies and even respond to incidents effectively. This approach makes it possible to effectively identify threats and issue real-time alerts, directly notifying plant managers and/or operators of potential attacks or operational failures, so they can anticipate and reduce their impact.

InprOTech GUARDIAN implements Artificial Intelligence and Machine Learning to guarantee plant security. It uses a wide variety of algorithms, from those that analyse network traffic to detect possible anomalies, to others focused on the analysis of process variables.

These algorithms can be combined in multiple layers of network security, significantly increasing security, allowing them to learn and adapt to each environment, offering a customised and efficient cybersecurity solution for each plant.

Summary

As industrial environments are increasingly digitised and exposed to advanced threats, Artificial Intelligence has become a key pillar to strengthen cybersecurity. Its ability to detect anomalies and anticipate risks offers a great advantage in dealing with constantly evolving cyber-attacks.

However, despite its great potential, this technology also presents many challenges that need to be addressed strategically and responsibly.

In this context, InprOTech GUARDIAN represents an example of the potential of AI applied to OT environments, combining advanced algorithms and adaptation to the environment that provides personalised protection.

The adoption of Artificial Intelligence not only enhances the resilience of industrial infrastructures, but also paves the way to a new era of more proactive, autonomous and trusted industrial cybersecurity.
