Currently, there is a constant evolution in the technologies and implementations made in Industrial Control Systems. On one hand, some of the most common implementations for the improvement of industrial systems infrastructures are digitalization and the use of cloud technology. On the other hand, the increase in communication protocols and IIoT devices (due to the growth of the Industry 4.0) generates a large volume of traffic that is difficult to control and secure.

The TETRA (Terrestrial Trunked Radio) network is a standard developed in Europe in the 1990s by ETSI (European Telecommunications Standards Institute), whose emergence came because of the management of telephone communications for extreme cases, in which standard communication via mobile might not work properly. Therefore, it can be considered as an alternative network for communications with emergency and security services to be always operational. TETRA unifies different digital radio interface alternatives for communications and serves as a standard for the construction of private mobile networks or PMR (Private Mobile Radio).

Within the industrial world, there are some sectors such as robotics, which has evolver considerably. This has led to the need to update all the regulations and standards, both in terms of physical (safety) and cybersecurity. (security). Given that the robotics sector is and will increasingly become a highly technical sector with exponential growth, the need to update all documentation has been promoted by a large group of companies in the sector, which, above all, have focused their concerns on the cybersecurity of the industrial robotics world.

Energy efficiency alternatives are nowadays on everyone’s lips given the energy crisis that is plaguing the vast majority of European regions. In Spain, the energetic companies are following alternatives based on the use of different technologies to solve problems as complex as such as the management of surplus energy in some infrastructures. One of the alternatives that seems to have greater depth within the sector is the use of Virtual Power Plant (VPP). This new concept of energy management makes it possible to interweave different energy sources into a single flow of electricity demand, managed through a global solution that is usually deployed in the cloud due to the amount of data that has to be processed. The management system proposed by Virtual Power Plant is simple: Take advantage of surplus energy from microgrids to balance supplies to infrastructures that need this energy. With this gesture, large distributors can take advantage of up to almost 100% of the power within all infrastructures, such as electric vehicle chargers, solar farms, wind turbine farms, etc.

The proliferation of cybersecurity incidents in industrial environments has given rise to a huge concern in the various existing sectors. Some of them, such us the energy sector, are choosing the path taking in the banking sector with the TIBER-EU framework. In addition, many governments are allocating large sums of money to their government agencies to develop strategic plans in which that exercises are included

Confrontations between countries no longer only take place in the physical world, in this new decade, these confrontations also move to the cyber world. The conflict between Russia and Ukraine is one of the clearest examples. Among the events that have taken place is the security incident known as Industroyer2, which affected an electrical supplier in Ukraine. The Industroyer2 is the evolution of its predecessor, the malware known as Industroyer, which was able to affect multiple protocols of industrial control systems during its execution. This new variant of the malware focuses on a particular communications protocol, IEC-104, which is widely used in Europe and the Middle East to monitor and control the power system via the TCP/IP communications protocol.

The programming of PLCs is a fundamental part of the initial phases when building and designing industrial plants. About that environment, the company will base all its operations in that environment making the configuration of these controllers a critical element. When it comes to programming these devices there are a series of steps and best practices that take advantage of the native functionalities available and that involve little or no need to resort to a PLC programmer, protecting the device in a simple way with minimum spend on resource.

In the year 2022 and as is reflected in the article “Industrial Security 2022 in numbers”, cyberattacks in all industrial sectors have increased by around 30 % in the third quarter of 2022 and it is estimated that the number of organizations or industrial manufacturers victims of a cyberattack was around 40% in the last year. Especially in the industrial sector, the number of attacks has grown exponentially due to the massive introduction of IoT devices (it is expected to go from 13.5 to 21.5 million connected devices in three years) or more specifically about IIoT devices, which have been the main gateway for attacks as manufacturers have prioritized features and mass-production of devices over the security. In addition, this is compounded by planned obsolescence planned (increasingly present in this type of devices), increased interoperability and connectivity and the appearance of new types of malware and exploits which are much more effective.

After the establishment of the cloud technology in industrial environments to provide processes a greater intelligence, new technological challenges arise that give rise to technical implementation solutions such as edge computing. This strategy makes it possible to extend cloud environments to different locations for processing collected data from the environment locally and immediately. An example of this new technological paradigm can be seen in modern manufacturing plants where sensors (IIoT) generate a constant flow of data to prevent breakdowns, improve operations, etc. Given that amount of data that can be generated, it is faster and more profitable to process the data in a close position from the equipment rather than transmitting It to a remote data center.

The increase in industrial control systems and the shortcomings of those systems in cybersecurity measures have made such systems a preferred target of attacks. The number of tools designed to pose a threat to the OT sector has increased, and the use of the Incontroller tool is especially concerning.

PLCs, or Programmable Logic Controllers, have been part of industrial environments since the birth of automation. Given their evolution over time, thanks to greater intelligence, they have become a target of interest for potential attackers.
