Industrial Systems Cybersecurity: Protect your production tools against cyber threats!

Computer systems and industrial facilities are increasingly interconnected with the outside world through their use of telecommunications technologies. Their connections to office networks, ERPs, and the proliferation of remote controls are all potential entry points for cyber attackers. As a result, your infrastructure and confidential data become vulnerable to hacking attempts in your cyber space. This leads to a reduction in your level of computer security and weakens your defense against malware and other phishing attempts. Obsolete industrial infrastructures can transform into a threat to the resilience of your operations and interconnected systems. Discover how SERMA Safety and Security helps you implement a protection policy for preserving the cybersecurity of your industrial systems.

Security and Adaptation: The Challenges of Operational Security in the Era of Industry 4.0

The development of Industry 4.0 involves 5G technologies, digital platforms, virtual reality, and all of your interconnected systems. The vast majority of French industrial sites, established several decades ago, are still inadequately prepared to meet the security requirements of this ever-evolving environment. This presents a security challenge, requiring a greater emphasis on defending your sensitive data.

Among the identified vulnerabilities, it is common to observe various problematic points in the maintenance of an industrial network:

  • They use legacy production systems with a design that is difficult to rectify;
  • They follow communication protocols and processes that are poorly or undocumented, often proprietary;
  • They have a production system with a high need for availability, risking significant financial and operational consequences in the event of downtime;
  • At best, asset mapping and tracking of connected equipment are not performed, and at worst, not achievable.

Our challenge is to prevent crisis management by implementing a modernized organization, designing a functional architecture that meets business requirements while ensuring its industrial integrity. We must ensure the availability of your equipment during risk prevention operations, provide protection for exchanges, and ensure data confidentiality between systems. Digital trust must be continuously guaranteed.

 

SERMA Safety and Security puts its expertise at your service and accompanies you in your large-scale projects and in the realisation of services with high added value.

CERMA by SERMA: the key to customized industrial system cybersecurity.

SERMA Safety and Security has developed the methodology ‘CERMA – Cybersecurity Evaluation and Risk Management’ to assist industrial companies. We leverage our expertise to secure your infrastructure by implementing technical and organizational levels of protection capable of addressing potential cyberattacks on your software.

This comprehensive process involves providing you with a personalized audit of your current setup while considering the requirements related to your business. It includes:

1/ Inventory of existing installations

  • Maturity” diagnostic (flash or detailed version) to assess strengths and actions to be taken in the short, medium and long term, including mapping of assets against digital security standards and best practice.
  • Compliance” audit to assess the requirements of IEC 62443, NIST SP800-82/SP800-53 or other customer specific standards.

4/ Support for the implementation of cybersecurity measures

  • Assistance in drafting a call for tenders or support in responding to calls for tenders
  • Implementation of processes and documentation aimed at raising the level of security, including crisis management (incident, business continuity, etc.) in the event of a cyber attack
  • Design of architectures and deployment of solutions in the customer context following good security practices
  • Technical documentation: DAT, DI, DR, DEX
  • Management, deployment, migration and production start-up
  • Support, Maintenance, Technical Support Contract (CAST)
  • Setting up a SOC (Security Operations Centre)
  • Supplier audit, support and monitoring (ISO/IEC)
  • Technology monitoring

2/ Risk analysis

  • Industrial cyber risk analysis, based on EBIOS Risk Manager and the recommendations of the IEC 62443 standard, which integrates the specificities of IEC 62443 and in particular the zone and duct approach.

3/ Proposals for organisational and technical security measures

  • Architecture definition (defence in depth approach)
  • Proposal of security measures (organisational and technical)
  • Removable media decontamination and data transfer
  • Security supervision

5/ Maintenance of security conditions, intrusion tests

Our qualified experts in the security and safety of industrial systems are trained to carry out meticulous assessments. They map your current setup using a precise methodology and identify vulnerabilities in the technologies used daily by your teams. They comprehensively review the risks to precisely identify potential entry points exploited by hackers to compromise your operating systems. They review your existing protections, such as firewalls, proxies, IPS, WAF, VPN, SSL, and PKI, and test your internal and external systems, including your industrial operating systems, workstations, applications, Wi-Fi, Bluetooth, and mobile devices.

Once the mapping of your setup is completed, like security architects, we provide you with comprehensive organizational and technical protective measures. We accompany you throughout this process to oversee the implementation of concrete cyber defense solutions. These practices aim to effectively combat any malicious intrusion attempts on your connected industrial devices and mitigate security incidents.

Our recommendations and actions ensure the protection of the interconnections within your industrial setup. Whether it concerns your ERP, automated devices, office networks, databases, or any other remote control interface, no threat is overlooked in order to protect you. We conduct penetration tests, also known as penetration testing, to strengthen our security measures and challenge our means of preventing cyberattacks. This process assesses the effectiveness of the measures in place and reinforces all installed protections to combat cybercrime.
