In order to increase security levels in OT networks, there are now solutions that monitor networks, devices and configurations, actively looking for anomalies and possible security flaws and intrusions that could take place. However, there are other types of attacks on ICS that are carried out on a completely different plane, where anomaly analysis systems can’t reach. These are attacks on analog sensors.
Specialized blog with informative contents destined to a public with marked technical profile, in order to improve knowledge and create a culture about the security in Internet.

This post explains the infrastructure of command and control (C&C), describing what an attack consists of, related terminology, actions undertaken by attackers, models, general function and preventative measures, detection and response to this threat.
Demilitarized zones, also known as DMZs (demilitarized zones), are used for the secure exchange of information between computers on a network that we want to protect and an external network that needs to access those computers. DMZs are widely used in the IT sector and also in the OT sector, but the equipment and services they host are not exactly the same.
Although the use of black channel is associated with physical safety, it is also part of logical safety. Here we can see how the black channel intervenes in communications, its contribution, advantages, use cases and the differences between it and the white channel.
An adequate level of cybersecurity and cyberresilience is essential to keep assets safe from possible cyberattacks. This is why INCIBE-CERT has listed a set of measures and good practices that are valid for any need that affects cybersecurity.
This post will analyse the vulnerabilities associated with Log4Shell, detected in the library Log4j, which is found in infinite software products both in technical and industrial fields. Although there have been other instances of more sophisticated vulnerabilities, the problem with this one is area of exposure.
Not all industrial control systems operate with the same programming language given that, depending on the manufacturer, devices will work with a specific software and programming language. This may be a problem for plant managers in industrial systems, as the interconnectivity between devices becomes impossible, or at least, is further complicated. One solution that has emerged in order to connect systems from different operating systems is CORBA standard and CORBAsec, its development with added security.
Cyberattacks using ransomware are one of the main threats for companies all over the world, and Spain is the tenth most affected country. This article, the first in a series dedicated to this subject, will provide a detailed list of recommendations for preventative measures dedicated to hardening in order to deal with such attacks.
With the arrival of industry 4.0 to companies’ productive processes, including IIoT and Cloud, the need to control and monitor the ICS that remotely make them up arises. However, said access points should be established securely and in a controlled manner, mainly due to the criticality of these assets. This article discusses good practices, tools and methods that can be used to establish remote connections to OT networks as securely as possible.
