The Initial Access tactic is one of the 12 tactics that make up the matrix developed by MITRE for industrial environments (for more information on the matrix, feel free to consult the article ICS Matrix, the State of v11). Within this tactic, different techniques used by attackers with the aim of gaining unauthorized access to an industrial environment are shown. This is often the first target of external attackers, as access to the ICS's internal environment allows internal computers to be recognized and exploited, move around the network, gain elevated privileges, or steal sensitive information. Therefore, it is important to know this tactic in order to defend our systems

This article aims to present a brief example guide for an implementation of the new standard in a supplier's facilities.

Going through the critical points of the standard, a generic use case will be followed to exemplify how a vehicle manufacturer can adapt its processes to comply with the new standard in an efficient and effective way.

By presenting an overview of the standard and production processes, the aim is to provide a brief guide to serve as a starting point and help avoid common failures in industrial environments when faced with new regulations, such as redundancy of effort, inefficiency in resource management and deficiencies in the application of safety measures.

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.

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 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.
