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.
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.
This post sets out some lines of action that must be followed to deal with a DrDoS cyberattack based on the mDNS protocol; it describes in detail the prevention, identification and response phases that must be undertaken.

In recent years we have witnessed the evolution of the electrical grid and the development of new technologies produce what we know today as the smart grid. This evolution continues to this day and the trend seems to point to greater interconnection between end consumers and the grid, which increases possible attack vectors. Over the course of this article, we shall see the security measures that will be used in the electrical grid of the future.
This article reviews the origin and development of the best-known types of denial-of-service attacks, placing special emphasis on Reflected Distributed Denial of Service attacks, analysing their main characteristics, operation, and consequences, as well as the measures necessary to mount a good defence against them.
