In industrial environments there are a multitude of technologies, manufacturers, communications, etc. This article will reflect a small part of the protocols that use radio frequency (RF) communications. Thanks to these wireless communications, operators in the industrial world can send a simple order to obtain information on the status of a sensor or execute control orders in the industrial environment. The importance of a good implementation, in terms of cybersecurity of these communications, is quite high since, on occasions, some of the attacks that have been investigated have an impact on the physical world, giving rise to incidents that can even result in fatalities.
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.
