In the era of interconnection and digitization, industrial control systems (ICS) are increasingly exposed to cyber threats. These systems are vital for energy production, manufacturing and critical infrastructure management, and their protection has become an essential priority.Risk analysis is fundamental in this context, as it allows identifying, assessing and prioritizing the risks that can affect ICS. This process, ranges from technical vulnerabilities to emerging threats, and is crucial for developing effective mitigation and protection strategies.In this article, the challenges and solutions related to risk analysis in ICS will be explored, as well as the importance of the IEC 62443-3-2 standard in this critical process.

The digital twins are virtual recreations of real-world objects or processes. This innovative idea, proposed by Dr. Michael Grieves, has become increasingly relevant in various industrial sectors thanks to the advancement of technologies such as 3D modelling, the Internet of Things (IoT), the IIoT (Industrial Internet of Things), machine learning and big data. Its application makes it possible to simulate and analyse physical processes efficiently, thus contributing to the digital transformation of industry, also known as Industry 4.0.The fundamental purpose of digital twins is to facilitate the understanding of how elements operate in the physical world. For example, in manufacturing, it is possible to create a digital twin of a factory and through simulations explore different scenarios: what would happen if a machine were modified, how would it impact production, and what would happen if a machine were changed? The digital twin provides answers before real changes are made to the physical environment, speeding up decision-making and optimising processes.

The ability to monitor and analyze the behavior of users and entities becomes crucial for early detection and response to potential threats. UEBA solutions identify unusual or anomalous patterns in user behavior, enabling rapid identification of internal threats or external compromises. This post focuses on how UEBA analysis is becoming an essential tool for a cybersecurity strategy, from identifying suspicious behavior to preventing potential security breaches.

Durante este artículo indagaremos en el funcionamiento y objetivos de una nueva tecnología de nueva adopción en el campo de la ciberseguridad, consistente en la creación de señuelos o información engañosa dentro de un Sistema de Control Industrial, permitiendo detectar y retrasar la intrusión de un ciberatacantes en un tiempo menor.

The agri-food sector is one of the most critical sectors today because it is one of the most important sectors for the country's economy, as it produces food.This sector, like many others, is in continuous evolution. An example of this is the automation and digitalization of the many processes that are carried out. These new technologies bring many advantages, such as more efficient processes, less water consumption, detection of possible risks, etc. These great advantages also bring with them some problems, such as increased exposure to cyber-attacks.Therefore, this article provides some basic knowledge to make the industry aware of the importance of implementing cybersecurity in their technologies. 

In the field of cybersecurity, CASB systems play a crucial role in providing an additional layer of protection for cloud applications. This approach prevents threats, detects malware, and ensures privacy in a digital environment, thereby addressing the growing need for data protection. This article explores how CASB systems work, their key applications, and their benefits in terms of security and privacy, ensuring that applications operate by protecting data in cloud environments and maintaining fine-grained control over cloud operations. From vendor assessment to malicious behavior detection, its versatility extends, offering benefits such as risk mitigation and improved cloud security.

There are currently many standards and regulations in the industrial sector. A wide variety of them allow industrial organizations to check their level of maturity, such as IEC 62443, or to improve the security level of the organization through the application of a series of guidelines, good practices or guides, as in the case of the NIST Framework.Given the growth of the industrial sector, and the increase in capabilities, both in production and connectivity, thanks to the consolidation of Industry 4.0 and the emergence of Industry 5.0, industrial environments are in the focus, not only of technological improvements, but also of cyber-attacks.The application and implementation of the IEC 62443 family, in combination with the NIST Framework, will enable organizations to reduce, mitigate and control the possibility of suffering a cyber-attack by implementing the controls and best practices defined in both standards.

UMAS (Unified Messaging Application Services) is a Schneider Electric (SE) proprietary protocol used to configure and monitor Schneider Electric programmable logic controllers (PLCs). While it is true that the protocol is related to this manufacturer, the use of the protocol is quite widespread in different sectors, especially the energy sector, as is obvious.The article will focus on the technical breakdown of the protocol and the use of the protocol. The article will also show weaknesses, strengths and some technical vulnerabilities detected in this protocol.

In today's business landscape, the digital revolution has led to an unprecedented transformation, and at the epicenter of this evolution are Industrial Internet of Things devices (IIoT). These devices, skilled in collecting and transmitting data in real-time, have emerged as fundamental pillars, that drive operational efficiency and decision-making in industrial environments.From advanved sensors to smart sctuators, the network of IIoT devices implemented in the industrial fabric is improving the frontiers of connectivity, impacting the way companies design, implement, and manage their operations.In this article, we will learn about the role of these devices within Industry 4.0, analyzing how different types of architectures are implemented and how their communications protocols shape the future of the industry. 

The UN R155 and UN R156 regulations are of vital importance for vehicle cybersecurity. From July 2022, all car manufacturers that want to be type-approved must comply with both regulations, but from July 2024 this requirement will be extended to all new vehicles sold in the European Union, regardless of when the manufacturer obtained type-approval. One of the most important aspects of compliance with both regulations is the completion of a cybersecurity risk assessment of the vehicle, including all integrated components of the vehicle's supply chain. On the other hand, it also specifies how to incorporate cybersecurity from design, how to detect and respond to incidents, how to securely update vehicle software, etc. 

En la actualidad, el crecimiento de las plantas industriales ha provocado una incesante búsqueda en la mejora de la productividad de los procesos industriales. Esto ha llevado a la evolución de los dispositivos IIoT y, con ello, la emergencia de las pasarelas ICS. Estas se han postulado como puentes tecnológicos, tendiendo vínculos, puentes, entre los dispositivos instalados y la inmensidad de los entornos cloud. En este artículo descubrirás el papel central de estas pasarelas, descubriendo su función como facilitadoras esenciales en la convergencia de la ingeniería tradicional y la innovación en la nube.
