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.

Today, it is common to find SIEM deployed in the IT infrastructures of all kinds of organisations, to be able to monitor and analyse security alerts in applications, systems, network devices, etc. However, though time and resources are being invested in industrial environments, it is still unresolved.

The honeypots, the recommended requirements for their correct implementation, the different possible types and their evolution until today, where they are implemented forming a honeynet.

Perhaps, given the many important cybersecurity leaks and intrusions in recent years involving everything from social media accounts to critical infrastructure and classified military secrets, the attention paid to the Aurora vulnerability has not been proportional to its seriousness and systems affected. This is because it affects almost every electrical system in the world, and potentially any rotating equipment, whether it generates energy or is essential for an industrial or commercial installation. If the threat is so widespread, why isn’t the industry more worried and actively looking for solutions? From this article various possible reasons for this are given.

The main security standards and best practice guidelines in industrial cybersecurity include as a requirement the need for a user authentication system. The options involve implementations in each device of this system or being integrated into a centralised user authentication system. One of the most-used options is the use of the LDAP protocol, but there are a number of points to consider in the design phase, which are key when implementing a specific centralised user management system for industrial control systems, under LDAP.

In recent years there has been an increase in interconnectivity between devices thanks to the Internet of Things (IoT). This has affected all sectors, including industry, which has been involved in an era of connectivity of industrial devices. This concept is known as the Industrial Internet of Things (IIoT).

A BusyBox is software or a program that combines several functionalities in a small executable. This small tool was created for use in integrated operating systems with very limited resources, and they are usually used in control systems. But, as in all tools, you have to know what security level they have and if it can be improved.

In the industrial world there are many communications including radio communications. This article aims to inform the reader about these types of communications available and some concepts to consider. Also, about cases of cyberattacks that have been detected in order to prevent them in the future.

The union of the IT and OT worlds is unstoppable, which means that the cybersecurity strategy, traditionally focused on the IT field, must now include aspects related to the industrial world. Having a good cybersecurity strategy is essential for IC systems to survive in this new era.
