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.
Context in the measurement of cyberresilience at the national level

Context in the measurement of cyberresilience indicators at the national level

Posted on 10/27/2022, by INCIBE
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.
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 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.

Posted on 03/10/2022, by INCIBE
Standard 62443 arose as a development the ISA 99 standard to fully cover security within control systems. Divided into several parts, each refers to different aspects related to security. The IEC 62443-3-3 standard refers to system security requirements and security levels.
MITRE matrix: TTP in ICS

The MITRE matrix: tactics and techniques in industrial settings

Posted on 02/03/2022, by INCIBE
Monitoring and analyzing security incidents in Industrial Control Systems (ICS) has been a priority for many organizations for a while now. As a response to this need, and given the great success in other areas specialized in cybersecurity, the MITRE organization has developed a matrix that collects many of the tactics, techniques and procedures detected in the industrial world. This article seeks to make the contents and potential uses of said matrix known.
CORBAsec security in CORBA middleware

CORBAsec: security in CORBA middleware

Posted on 01/20/2022, by INCIBE
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.
