Securing industrial information systems: beginner level?

Securing industrial information systems: beginner level?

After many years, the globalization of the progress of the industry, the increase in customer demands and the permanent spread of a low country have resulted in a strong advance of industrial circles.

Moreover, the collaboration of security and security actors of Information Systems Security (SI) is more important than ever to protect and strengthen the competitiveness of companies. From this perspective, you can use this collaboration to make it freer or easier – your own flexibility and robustness.

On the other hand, the safety of critical infrastructures using industrial control systems – et plus partulièrement pour les opérateurs d’importance vitale – is imposed as a fundamental priority. This finding is d’autant plus vrai after the emergence and increase of risks in industrial systems that started in the 2010s.

The origin is the stand-alone work environment, systems need to be integrated or integrated to respond to the production requirements of the business. Emerging developments, of course, installation information systems piloting information systems are emerging outdoors, which exposes them to new risks, which may be the most important plus of precision.

This results in the failure of composition techniques used in industry control systems and generally aids in the preparation of cyber attacks in the field. For other domains of cybersecurity, see first answers from leading organizational leading technologies.

What is the difference between a traditional SI and an industrial SI?

An initiative of SI industries is the best way to consolidate hardware and move faster from key points on the planet, reducing development and ownership costs, accelerating the convergence of domains. ‘Industrial et de gestion informatique.

Contrary to SI traditions and software conceptualizations for the correction of the security end, as well as the root causes of the eux-mêmes, le fielde ndustriel, en raison mainmente de disponibilité contraintes and de fonctionnement, the security sont fixes published without the consent of the adopter Method of use, mode of operation. This difference in treatment, facing vulnerabilities is one of the main risk factors posed by industrial control systems.

The main difference between the sensitivity of industrial IS and management IS has to do with prioritizing security requirements by type of nefarious. Au-delà des classiques critères de secretité, intégrité and disponibilité, s’ajoutent également des exigences à la sécurité physique, à l’vironnement, la santé, la dépendance and la regulation…

What are the different vulnerabilities of SI industries?

Vulnerabilities in SI industries are as follows:

> architecture eat it cartography du SI : The absence of an inventory of the SI park, the equipment and vision of the technological generations and its internal vulnerabilities, an analysis of the risks of the SI industries or a continuity plan and duplication of activities.

> Measures anti-aux techniques : mauvaise the use of admin computers, reward tools at non-security main distances, shredding access files completed on course access, accessing or accessing configuration files via FTP or TFTP, mot de passe par defaut to les comptes de services, data bases and acès en mode console ( controller logic programmable « PLC », passerelles, réseau équipements)

> Permanent Security : absence of political portables, blocking of USB ports, lack of configuration of hardware, equipment and code source, lack of log mechanism correcting exploit systems, applications etc. firmwareabsence of signature mechanism firmware).

Comment donc security provider activity in SI industries?

Systems used in industry can achieve more from information technology, but not enough to face the threats that may arise. Examples of publishing vulnerabilities in industrial systems are anonymous (Modbus and OPC protocols are a good example).

C’est pourquoi, l’entreprise This is what is needed to integrate the reflection of the SI de l’enterprise (security culture) in générale sur la sécurité.

Two strategies are best suited for securing environments.

tout d’abord, security by design This is an integration strategy for cybersecurity in all company projects that are in the specification, design, integration or testing phase.

Il ne s’agitiifier les démarches et processus, mais plutôt d’integrer les enjeux de cybersécurité dans les différentes méthodes des risques réalisées historiquement – ​​notamment cels de sûreté – don’t l’AMDEC desésfas, d’AMDEC, Effices et de leur Criticité) or HAZOP (analyse de risques et de sécurité de fonctionnement), as well as ownership of cybersecurity integration source codes and parameters).

tandis that security post designmise en place des mesures de sécurité – installations and les systèmes anciens, architecture and cartographie des systèmes ndustriels (development, access read modification and sample PLC configuration helpers) – vient, manually, strengthen the security of default and unused equipment and optimize the security of industrial systems .

Certain existing installations and risks are suitable analyzers for deploying tailored solutions to limit impacts on the core business activity.

Securing installation can be difficult to guess. Successes are extremely successful. But the securitization process protects the company’s investments and production. This is a plus for the most important definitions of objects and adapters.

Caution, in addition, la sur-sécurité may have adverse effects on the performances of its industrial participants ceux recherchés and nuire aux. Ajouter à cela, the challenge for industry operators to understand effective risks and quantifiers…

L’écart de Culture – entre les les sécurité des SI d’un Côté and pratiques of the les manufacturing industry – mise d’organization in the management field can present Liées challenges.

Pallier cela is the basis for developing true collaboration at il est essentiel de deux parties – but also reflections of the responses to risky cyber and the security requirements of the two environments. Approaching the risks was enough to provide value and information to address the risks in the SI traditions, a place to accompany an accompanying excursion in the refonte and rouverture dances of the SI industries.
