OT/ICS systems and networks administration

This section provides content of interest to professionals in OT environments involved in managing and maintaining applications, systems, network equipment, managing users, access and services, technical support and OT incident response.

The tasks of these professionals are often similar to those of IT professionals, except that they deal with systems where availability is often more critical than confidentiality.

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.
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.
ML in ICS

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.

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 ICS

FAT and SAT tests on industrial devices

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.
Cybersecurity measures from a global perspective

Cybersecurity measures from a global perspective

Posted on 03/11/2022, by INCIBE
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.
