In this article, we review virtual private networks, or VPNs, one of the most important measures for teleworking, as they allow a connection to the organization through secure networks, and the advantages they offer, as well as additional security recommendations to help ensure cyber security.

The first step in securing industrial control systems is making an inventory containing all the assets involved in the process. With this information, the inventory can be used to properly manage vulnerabilities, which will make it possible to take the necessary measures to solve and mitigate them.

Time synchronization in industrial devices is a critical factor. In terms of time, industrial processes and the programming logic of industrial devices have specific needs. These may require specific accuracy that determines the need to use one protocol or another, as well as dependencies on cost or on the network infrastructure itself. Explaining the main differences is key when using one or another in industrial infrastructures. Just as each protocol has different nuances, there are certain differences to be taken into account within security.

The Modbus protocol, in its TCP version, was not developed with cybersecurity capabilities in its communications. For this reason, many researchers have studied the different possibilities that could be undertaken at the technical level to incorporate a security layer in it, giving rise to a new version of Modbus/TCP called secure Modbus/TCP, which will gradually begin to be implemented in industrial communications.

Over the last few years we have seen how electric vehicles have experienced a boom in terms of their development and retail and, along with them, the deployment of their charging points. In this article we will discuss a series of requirements, in terms of security, that should be implemented in these charging stations in order to ensure their security.

Throughout the year 2019, we have worked on the detection, treatment and preparation of notices related to cybersecurity in industrial environments, classifying them based on the sector, manufacturer, criticality, etc. This article summarises this work and makes a brief prediction of the events that will take place in 2020.

Electric charging stations are increasingly used in urban furniture in cities. Electric cars and their need to be charged are a reality. Because of this, there is an increase in supply points that depend on specific protocols and communications for these stations.

Wireless networks are constantly evolving. As a result, 5G technology is born, continuing the roll-out of mobile phones and other associated services. This new technology is in an advanced stage of development and is already included in a multitude of next-generation devices. In fact, its deployment applied to mobile networks is already being done in numerous major cities in our country.

Over the years, the automotive sector has been growing and evolving technologically. During this time, different deficiencies or vulnerabilities in smart cars have been discovered. For this reason, one of the key issues for this new type of vehicle is protection against possible threats.
