System hardening: the case of Linux

Posted on 03/02/2023, by INCIBE
Knowing the resources available when performing tasks of hardening a system, will allow us to optimize the time necessary to obtain a safer system. In addition, we have the possibility of using tools capable of auditing the system that identifies those configurations that are considered safe and which ones we could implement.

Industroyer2, the ampere strikes back

Posted on 02/09/2023, by INCIBE
Confrontations between countries no longer only take place in the physical world, in this new decade, these confrontations also move to the cyber world. The conflict between Russia and Ukraine is one of the clearest examples. Among the events that have taken place is the security incident known as Industroyer2, which affected an electrical supplier in Ukraine. The Industroyer2 is the evolution of its predecessor, the malware known as Industroyer, which was able to affect multiple protocols of industrial control systems during its execution. This new variant of the malware focuses on a particular communications protocol, IEC-104, which is widely used in Europe and the Middle East to monitor and control the power system via the TCP/IP communications protocol.

Secure programming techniques for PLC

Posted on 02/02/2023, by INCIBE
The programming of PLCs is a fundamental part of the initial phases when building and designing industrial plants. About that environment, the company will base all its operations in that environment making the configuration of these controllers a critical element. When it comes to programming these devices there are a series of steps and best practices that take advantage of the native functionalities available and that involve little or no need to resort to a PLC programmer, protecting the device in a simple way with minimum spend on resource.

What to expect from the industrial cybersecurity in 2023?

Posted on 01/26/2023, by INCIBE
In the year 2022 and as is reflected in the article “Industrial Security 2022 in numbers”, cyberattacks in all industrial sectors have increased by around 30 % in the third quarter of 2022 and it is estimated that the number of organizations or industrial manufacturers victims of a cyberattack was around 40% in the last year. Especially in the industrial sector, the number of attacks has grown exponentially due to the massive introduction of IoT devices (it is expected to go from 13.5 to 21.5 million connected devices in three years) or more specifically about IIoT devices, which have been the main gateway for attacks as manufacturers have prioritized features and mass-production of devices over the security. In addition, this is compounded by planned obsolescence planned (increasingly present in this type of devices), increased interoperability and connectivity and the appearance of new types of malware and exploits which are much more effective.

Edge computing the future in computation

Posted on 01/11/2023, by INCIBE
After the establishment of the cloud technology in industrial environments to provide processes a greater intelligence, new technological challenges arise that give rise to technical implementation solutions such as edge computing. This strategy makes it possible to extend cloud environments to different locations for processing collected data from the environment locally and immediately. An example of this new technological paradigm can be seen in modern manufacturing plants where sensors (IIoT) generate a constant flow of data to prevent breakdowns, improve operations, etc. Given that amount of data that can be generated, it is faster and more profitable to process the data in a close position from the equipment rather than transmitting It to a remote data center.

Es tanta la información que se encuentra actualmente accesible para los usuarios en Internet, que aquella ofrecida por ciertas páginas web o aplicaciones en tiempo real puede resultar de especial preocupación en cuanto a su confidencialidad para ciertos sectores, dado que podría ser utilizada con fines malintencionados.

Attacks on analog sensors in OT

Posted on 10/06/2022, by INCIBE
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.

Log4Shell: analysis of vulnerabilities in Log4j

Posted on 02/24/2022, by INCIBE
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.
