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.

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.
Advances in security within control systems have brought us many of the security tools and services offered in IT for this environment. Until now, protection was based on reactive measures, acting only where there was evidence of the attack, but this trend changed with deployment of monitoring and the proactive defensive actions that this can provide.
The defence in depth and, especially, the definition of Zones and Conduits is a subject considered by many experts as a "theoretical" matter. However, with the help of this article, the user will understand its applicability by explaining the keys to approach the creation of Zones and Conduits, as well as the elements that come into play.
Honeypots and their implementation in a network, known as a honeynet, are a powerful tool for defending your system and safely monitoring the attacks carried out against it. In this article we will detail what honeypots are, their implementation in OT environments, the advantages and disadvantages of their implementation in the system and the latest honeypots developed for industrial control systems.
I have identified a vulnerability in a device within an industrial control system... Now what? This article provides the guidelines to be followed when a vulnerability within an industrial control system is detected, and the different phases of this process.
Denial-of-service attacks are a type of cyber-attack which consists on reducing or cancelling altogether the capacity of servers or other computing resources to provide service. A denial-of-service attack can occur in different scenarios, such as overloading online services by mass request sending or exploiting vulnerabilities of programs or services in order to suspend function totally or partially. In most of such attacks, attackers use a wide range of techniques and tools to hide their identities, which makes it especially challenging to find the culprits.
Carrying out an intrusion test or vulnerability analysis in a control system can prove complex due to availability. This is where testbeds come into play. They reproduce production environments and can be of great assistance to researchers and security analysts
