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.

How to prevent an antivirus bypass

Posted on 12/29/2022, by INCIBE
Antivirus is one of the main lines of defence when a user downloads a malicious file or an attacker has gained access to the computer and attempts to execute malware. Cybercriminals use various means to avoid an antivirus, using different tools and techniques depending on their type and functionalities. This article details the techniques commonly used, as well as the protective measures we should take to prevent attackers from executing malware on our computers.

Context in the measurement of cyberresilience indicators at the national level

Organisations are exposed to the consequences of cyber threats, and may be ill-prepared to face and manage cyber incidents, whether provoked or unprovoked. For this reason, in 2014 INCIBE launched its Indicators for the Improvement of Cyber Resilience (IMC) model, with the aim of improving and understanding the state of cyber resilience in organisations.
OT DMZ vs IT DMZ

Differences between OT DMZ and IT DMZ

Posted on 08/04/2022, by INCIBE
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.

Machine learning in ICS

Posted on 06/23/2022, by INCIBE
In recent years, the concept of machine learning has gained more prominence, mainly driven by advances in parallel computing capacity. More and more developments, applications and programs are using these algorithms to provide systems with greater security, intelligence and independence. However, it’s rarely used in industrial environments, although some recent tests and developments prove its effectiveness, including in the scope of detection and prediction of cyber attacks.
Standard IEC 62443-4-2, the need to secure ISC components

IEC 62443-4-2, the need to secure components

Posted on 05/12/2022, by INCIBE
The security of control systems can be threatened from different aspects, with the end device being the most important attack vector. With this in mind, the IEC, within the 62443 standard, wanted to emphasise devices by preparing a document exclusively concerning their security: IEC62443-4-2. This document contains different technical requirements to improve the security of the types of assets that can be found in a control system.

FAT and SAT tests on industrial devices

Posted on 04/07/2022, by INCIBE
The continuity of the production process in businesses that require industrial automation depends more and more on the proper functioning, safety and reliability of the system of that composes it. Therefore, conducting tests of acceptance of its operation prior to its commissioning, is vital to ensure that the systems acquired meet the requirements set out in the contract between the company and the manufacturer.
