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.
Control system networks have grown immensely in recent years, something similar to what happened with the explosion of IT networks in the 1980s. This growth is happening somewhat chaotically, promoted mainly by productive needs and by the lack of joint definition of network administration managers for IT and OT, instead of doing it by thinking of the future, scalability and security.
ICS environments are made up of very heterogeneous machines, with large differences depending on the system we are dealing with. Some of these systems have very strict response time requirements for their correct operation and therefore use real-time operating systems. Throughout this article we will see what real-time operating systems are, how they work, and we will propose hardening measures to reduce the likelihood that these devices will suffer a cyberattack.
Over time, different communities of experts related to the world of industrial cybersecurity have realised the challenge of calculating the CVSS (Common Vulnerability Score System) for vulnerabilities in industrial environments. This article aims to show the alternatives proposed by experts, such as RSS-MD, TEMSL and IVSS in order to correctly calculate their severity in the industrial environment.
Trips across the ocean have changed over the years with the arrival of the industrial revolution and information technology, among other things, making technology its best ally, both to automate their navigation and to control their location from land-based stations. However, this total dependence on technology brings with it important security issues that need to be addressed with the importance they deserve.
The concept of defence in industrial environments is changing. Just as the attacks are increasingly more sophisticated, the protection systems tend to be more flexible and more evolved. Being able to strengthen the upper levels, such as active defence and intelligence, is essential, whilst always maintaining a solid base of the lower levels (passive defence and secure architecture).
