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.

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.
The open and most-widely-used framework for communication and vulnerability scoring, the CVSS (Common Vulnerability Scoring System), has been updated, incorporating improvements in its new version 3.1 with respect to the previous one. This standard assesses the severity of computer systems vulnerabilities and assigns them a score of 0 to 10.
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.
Security breaches that put our privacy at risk, leaks of our data, passwords... are incidents that happen more and more often. Protecting ourselves from these information leaks is often beyond our reach, but this does not mean that we should not try to take measures to protect our data. DNS-over-TLS can be very helpful in encrypting our communications, making them much more secure.
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).
Over the past few years, and especially after the arrival of the 4.0 industry, conferences, events and summits on industrial cybersecurity, and in general, all other topics related to industrial security and the IoT environment have been growing year upon year. This article will look at the main conferences on industrial cybersecurity both at national and international level.
Given that availability is always a critical point to take into account for within industrial environments, it is necessary to prevent the attacks that denial of services cause and that affect these environments. The means of giving way to a denial of service can be diverse, much like the means of mitigating these problems. This article will review all of these points, as well as the way in which the risks derived from these attacks can be reduced.
The wireless protocols used in industrial environments for communication between devices are numerous are extensive, therefore ensuring these communications is vital for industrial process to function correctly. In this article, we'll look at the advantages of wireless communication audits and the disadvantages of not performing them.
