The UN R155 and UN R156 regulations are of vital importance for vehicle cybersecurity. From July 2022, all car manufacturers that want to be type-approved must comply with both regulations, but from July 2024 this requirement will be extended to all new vehicles sold in the European Union, regardless of when the manufacturer obtained type-approval. One of the most important aspects of compliance with both regulations is the completion of a cybersecurity risk assessment of the vehicle, including all integrated components of the vehicle's supply chain. On the other hand, it also specifies how to incorporate cybersecurity from design, how to detect and respond to incidents, how to securely update vehicle software, etc.

IoT networks are very useful for everyday life, but their use is not limited only to this type of environment; there are industrial environments where this type of networks can benefit connectivity between industrial devices and provide capabilities that other types of networks could not. The 3rd Generation Partnership Project or 3GPP developed the NB-IoT protocol, a protocol for when networks with higher performance, higher speed and high interconnectivity capacity between devices are required. This protocol can work both in IoT devices and in IoT devices in the industrial environment (IIoT).

The OPC UA (OPC unified architecture) communication protocol is the most modern standard presented by OPC Foundation. Currently, the OPC UA protocol is one of the most widely used in industrial environments, due to its ability to interconnect different devices, regardless of their base protocol and vendor.

Throughout this article, a technical assessment of the protocol will be conducted, explaining in detail the technical capabilities that allow a high level of cybersecurity to be implemented without causing performance losses in the devices.

The evolution of communications in society is also having an impact on the industrial world. With the arrival of 5G, many industrial companies have considered migrating some of their communications to take advantage of the characteristics of this new mobile communications band, such as the reduction of latency times, the increase in connection speed or the exponential increase in the number of devices that can be connected to the network. These characteristics fit perfectly with the industrial mentality, where there are a multitude of interconnected devices between which there cannot be a communication cut due to the criticality of the processes they implement. 

This article aims to comment, in addition to all the advantages that 5G provides to the industry, the different uses that can be given currently and the complexity of implementing these communications in some devices for subsequent deployment in the industry. Also, to specify possible vulnerabilities in communications using 5G networks.

With the industrial revolution of Industry 4.0, industrial processes have become more intelligent, and this has led to the deployment of a greater number of devices. 

All these deployments usually have a common point, being the gateways, which, after being deployed, are responsible for the translation of some protocols to the TCP/UDP frame or simply send the information to the cloud.

Being a point that gathers a large amount of data and capable of providing intelligence to industrial processes, industrial gateways have become a very desirable target for attackers.
