A  CI/CD (Continuous Integration/Continuous Deployment) pipeline is an essential tool in modern software development, which allows you to automate and optimize the entire development lifecycle, from code integration to its deployment in production. The article aims to explain security in  CI/CD pipelines, motivating readers to adopt automated practices that not only optimize software development, but also minimize the associated risks. Keep in mind that automation carries certain risks if not handled safely, as it can increase the attack surface for cybercriminals. It underscores the importance of implementing security controls at every stage of the pipeline, urging developers to take initiative-taking steps to protect their code, their environments, and ultimately, their final products.

Larger scale and complexity industrial control networks present risks, and cybersecurity needs that usually cannot be met by applying a traditional segmentation model. Factors such as the presence of critical obsolete equipment, equipment managed by third parties or the increased presence of IoT technologies that require external connections, are motivating the adoption of more advanced architectures when applying the principle of defense in depth.Proper segmentation can be a fundamental aspect in preventing attacks, especially in their propagation to essential and critical production assets. It is also important to adapt to the environment to be segmented. It is a common mistake to try to segment networks based on concepts and schemes like the IT environment.This article will present some new network models and tips to work on a correct segmentation in an environment where different components are involved (OT, IIoT, IT, IoT).

Organizations face the constant challenge of adopting new security strategies, such as the Zero Trust model, which operates under the premise of "never trust, always verify." This change is crucial especially in cloud environments, where identity and resource access management is more complex. In particular, the Secure Web Gateway (SWG) is a key system, which focuses on controlling user access to the web, protecting against web-based threats, and enforcing security policies. It acts as an intermediary between users and the internet, filtering and inspecting web traffic to ensure it meets the organization's security requirements.However, implementing and managing SWGs presents significant challenges, such as integration with existing infrastructures, managing complexity, and scalability. These challenges require meticulous attention to ensure effective and efficient protection in the changing cybersecurity landscape. This article explores the purpose and function of SWGs, as well as their architecture, their ability to protect against cyber threats, and best practices for their implementation.

MITRE Caldera OT stands out mainly for being an open-source tool that allows the simulation of different cyber-attacks in industrial environments. This tool was created by MITRE and CISA (US Cybersecurity and Infrastructures Security Agency), as the experts saw the need to be able to improve and understand cybersecurity in industrial environments without using a high number of resources.In addition, this tool is designed to be used by both the Red Team and the Blue Team, allowing both teams to collaborate with each other to improve the level of cyber security in these environments.

The increasing development of malware targeting the industrial world has not halted its momentum in the slightest. Several research groups have detected a new malware called Fuxnet and are currently investigating its scope. This malware has the capability to send specific requests at the serial level, via RS485/MBus, executing floods to more than 87.000 assets, including control systems and integrated sensors deployed across different sectors. Among the infrastructures compromised by this malware, we find hospitals, airports and other critical infrastructures that provide essential services to the population.

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.
