The OPC UA (OPC unified architecture) communication protocol is the most modern standard presented by OPC Foundation. Currently, the OPC UA protocol is one of the most widely used in industrial environments, due to its ability to interconnect different devices, regardless of their base protocol and vendor.Throughout this article, a technical assessment of the protocol will be conducted, explaining in detail the technical capabilities that allow a high level of cybersecurity to be implemented without causing performance losses in the devices. 

Second part of the Top 20 mitigations for industrial environments. This part will focus on mitigations related to network architecture, industrial protocols, network configuration and vulnerability scanning.

In the industrial world, there are a large number of systems, equipment, networks, areas, ducts, cloud environments, IT-OT environments, etc. In recent years, the number of attacks on industrial environments has been growing exponentially, and not only on purely industrial environments, but also on corporate environments that are connected to industrial environments. These IT environments being access points for attackers due to this IT/OT connectivity.

The automotive sector is currently moving towards electric consumption, as society is becoming more and more aware of the problems that environmental pollution can cause.One of the big challenges of this trend is how to charge electric vehicles, for which charging points are currently used.But like most of today's technological devices, they will also need to have access to an Internet connection in order to be able to monitor in real time the use of the station, the customer's banking information, etc.For this reason, in this article we want to talk about the different risks or cyber-attacks that these charging points may suffer and the problems they may cause, as this is a very important sector for society and one that is capable of managing very sensitive information 

The arrival of the new version of CVSS (Common Vulnerability Scoring System) covers some deficiencies related to the assessment of vulnerabilities in the industrial world. The introduction of changes in the way of scoring different vulnerabilities, the incorporation of new metrics for elements of the industrial world such as "Safety" or the service recovery of a device, are some of the new features introduced in version 4 of the CVSS.This article will analyze the new features brought by version 4.0 and its increased accuracy when assessing vulnerabilities in industrial environments for a better adequacy of the scores given. 

In recent decades, the need to control processes remotely to improve efficiency, productivity and accelerate decision making on industrial systems has led to the interconnection of operation technologies (OT) with information technologies (IT). This interconnection has given rise to a number of security risks in industrial control systems, and to meet these challenges, specific tools and technologies have been developed and adapted to help ensure cybersecurity in industrial environments. One such tool is the Security Operations Center (SOC).In this article we will focus on the importance of advanced monitoring in a SOC OT. 

Firmware analysis can help to uncover potential vulnerabilities that would otherwise never have been discovered.Although there are multiple types of attacks on IoT and IIoT devices, this guide focuses on the firmware of these devices to check for potential vulnerabilities, using security testing and reverse engineering to allow for an in-depth analysis of the firmware.

The evolution of communications in society is also having an impact on the industrial world. With the arrival of 5G, many industrial companies have considered migrating some of their communications to take advantage of the characteristics of this new mobile communications band, such as the reduction of latency times, the increase in connection speed or the exponential increase in the number of devices that can be connected to the network. These characteristics fit perfectly with the industrial mentality, where there are a multitude of interconnected devices between which there cannot be a communication cut due to the criticality of the processes they implement. This article aims to comment, in addition to all the advantages that 5G provides to the industry, the different uses that can be given currently and the complexity of implementing these communications in some devices for subsequent deployment in the industry. Also, to specify possible vulnerabilities in communications using 5G networks.

External access provides great convenience to workers, as it allows them to access any industrial equipment deployed in the field from the office or even further away. However, this type of access can pose a number of security problems for the company. This article reviews the main problems and how to solve them.

The Purple Teams are exercises in which three very well differentiated teams participate: a Red Team, a Blue Team and a Purple Team. The Red Team will be in charge of carrying out attacks on the defined structure, the Blue Team will be the team in charge of defending that structure and the inclusion of the Purple Team allows the two previous teams to communicate with each other and be organized correctly thanks to the work of the purple team. This is why the Purple Teams allow a great number of advantages to be obtained with respect to carrying out the exercises separately and without coordination between them.This article presents all these advantages and much more about Purple Teams.

When a security incident occurs in an ICS (Industrial Control System), depending on the severity of the incident, it can generate a serious problem, both at a productive and economic level, as well as in the security of the people working in the industrial system.Therefore, in this article following the one entitled "Good practices for the recovery of industrial systems (I)", response plans will be discussed from a point of view oriented to current regulations, as well as their applications and necessity in critical industrial environments, such as the energy sector. 

When a security incident occurs in an ICS (Industrial Control System), depending on its severity, it can generate a serious problem, both at a productive and economic level, as well as in the security of the people working in the industrial system.Therefore, in this first article of a series on this subject, we will explain precisely the recovery plans, some general guidelines for their development and some conclusions on the use and applicability of these plans.
