The Road to a Defensible Architecture

Industrial operations are no longer isolated. The growing interconnection between IT and OT brings efficiency, but also exposes critical processes to cyber risks. 

With the arrival of the EU NIS2 directive and the adoption of the IEC 62443 standard family, organizations are expected not only to comply with regulation but to design architectures that are truly defensible.

Bridging OT and IT using NIS2 and IEC62443

This talk will cover the road in obtaining a resilient and defensible ICS network architecture to be able to withstand today's operational requirements and cybersecurity challenges. 

We will not only cover the bridging of OT and IT (mind the gap), but will also explore regulatory and standard frameworks, such as NIS2 and IEC 62443. These are used as resources towards your architectural needs while assuring that the needs for both operation resilience and effective defense posture are identified and maintained throughout the lifecycle of the facility. 

This talk highlights the possible consequences for the way of working for ICS staff & suppliers, dependencies on IT architecture, and risks from other networks, the Internet or adversaries.

By the end of the session, you will understand how NIS2 defines the “what”, IEC 62443 delivers the “how”, and how combining both enables a resilient and sustainable approach to OT/IT security.

Presented by Dieter Sarrazyn

Dieter is working extensively within operational technology and industrial environments since 2008 for which he provides security consultancy, assessments, training and awareness sessions with regards to industrial security.

He performs different kinds of maturity, risk and technical security assessments within these industrial environments. A large part is about helping organisations to manage security within new solutions deployed by their suppliers or integrators. This is done by setting up Vendor security validation programs, which consists in setting and verifying security requirements and performing security FAT and SAT tests.

He also helps industrial organisations in achieving NIS2 and IEC62443 compliancy.

Join the Discussion

This event is an excellent opportunity to network. It is free of charge, but registration is mandatory. After the presentations, you can join us for a networking drink, where we will keep the discussion and networking going.
