The increase of malware specifically designed to run on systems that support industrial processes creates a need in the industry that can be partly covered by different technological solutions. This article will focus on the different options available on the market to detect malicious files that aim to modify the operation of industrial environments or simply cause denials of service.Both portable and agent-deployed solutions can be an option, and this article will reflect on these and other options as well as provide guidelines on when it is best to use one solution or the other.

5G, a new SCI era
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.

Secure configurations in industrial devices Blog cover
Within the industrial world, systems can be detected that do not have all their cybersecurity capabilities activated. This can occur for a variety of reasons, but if detected, each case must be analyzed to get the most out of each device. The ability to robustly configure programs, services or other nuances within industrial systems is called bastioning and allows, among other things, to prevent assets from having a large exposure to the network or the solutions deployed in the system from having vulnerabilities resulting from misconfiguration.In this article, we will begin by explaining what hardening is and how to apply it to our industrial network, along with some good practices to follow.

The history of cybersecurity is marked by names that have left an indelible mark on the field of digital threats. Among them, Maze, Egregor and Sekhmet stand out as notable ransomware variants, whose similarities go beyond mere coincidence. In this article, we will unravel the tactics these ransomwares employed,  the encryption mechanisms they used, and the evasion and propagation strategies they employed. The review of these malware will offer us a deeper insight into the persistent threat of ransomware, as well as the importance and need to strengthen our cybersecurity posture.

All about Purple Team increases the effectiveness of the Red Team and the Blue Team in SCI
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.
