OT cybersecurity maturity assessment

Assessing the level of cybersecurity maturity of industrial systems (OT) is becoming a necessity: beyond the “classic” technologies used, specific and critical operational systems are being added, along with new cybersecurity requirements that increase the attack surface and associated vulnerabilities.

Historically insecure systems subject to specific constraints

How my organization meets the challenges of industrial information systems

  • Dependability, productivity and cybersecurity go hand in hand
  • Production scalability
  • Diversification of needs
  • Ability to react and limit production impacts
  • Real-time operation
  • High level of availability
  • Installations’ control and expertise (third-party access, technical documentation, etc.

How to keep up with the latest technological needs:

  • Growing demand for interconnections with IT information systems,
  • Remote interconnections (remote maintenance, etc.)
  • Adoption of Industry 4.0 (IIOT, robotization, 3D printing, digital simulation, etc.)

How to comply with an increasingly complex legal and compliance framework:

  • NIST standard, ISA/CEI 62443 etc.
  • Safety requirements (ISO 28000 / FMEA / HAZOP)
  • NIS Directive
  • Inter-ministerial general instructions: IGI 1300, 6600, PSSIE and RGS
  • Sector-specific requirements

Which security benchmark should you choose to assess your industrial cybersecurity maturity?

We recommend using standards specific to industrial information systems, such as NIST 800-53r (supplemented by NIST SP 800-82r2) or ISA/IEC 62443.

How can I find out exactly which components make up my industrial information system?

Interviews may not be enough to identify all the components making up a company's information system. In such cases, we use probes which, by passively listening in traffic at strategic points in the network, enable us to map all the components (probes, sensors, SCADA, etc.).

Should I wait until the plants are shut down before making my assessment?

In the case of an assessment based solely on interviews, this parameter is not important. On the other hand, if a technical analysis is to be carried out, it is necessary to keep the plants running in order to analyze the various flows exchanged.
