OT security architecture design
Zaprojektujemy dla Ciebie bezpieczną i odporną architekturę sieci przemysłowej, która od samego początku będzie chronić Twoją produkcję przed cyberatakami. Nasze projekty opieramy na najlepszych praktykach i standardach, takich jak model Purdue i norma IEC 62443, tworząc logicznie odizolowane i łatwe w zarządzaniu strefy bezpieczeństwa.
Your production network is “flat.” This is a straight road to disaster.
Many industrial networks have been built evolutionarily over the years, without an overarching security plan. The result is often a “flat” architecture in which all devices can communicate with all devices. In such an environment, one infected computer in an office can cripple an entire factory in minutes.
More than 75% of historical industrial networks lack proper segmentation.
True story: how one email to the front desk stopped a steel mill
In a large steel mill, the office network (IT) was connected to the production network (OT) without any buffer zone (DMZ). A front desk employee clicked on a malicious link in a phishing email, which infected his computer with ransomware.
Because the network was flat, the ransomware spread within an hour to the engineering stations and SCADA systems monitoring the furnaces. For security reasons, the entire technological process had to be stopped in an emergency.
The problem lay not in the sophistication of the attack, but in the architecture that allowed it. It made no sense to invest in modern firewalls when the network was designed without basic security zones.
Are you sure your network architecture is actively blocking the spread of threats, or are you just hoping that the first infection never happens?
Our solution: security built into the architecture (“by design”)
Security is not a device you can buy. It’s a well-thought-out architecture that makes a system inherently resilient. Our service is to create for you a logical and physical design of your OT network that anticipates the possibility of an incident and is designed to reduce its impact to an absolute minimum.
Our approach is based on 3 pillars:
Purdue model-based design
We create a multi-level architecture, logically separating the corporate network (IT) from the control systems (OT), according to IEC 62443.
Segmentation and DMZs
We design detailed network segmentation, creating isolated “zones” for individual processes and implement secure buffers (DMZs).
Access control planning
We define who and what can communicate between zones. We create restrictive rules so that only necessary traffic reaches critical systems.
Our design process in 5 steps
From understanding your business goals to the finished implementation project.
Step 1
Analysis of architecture and business objectives
We start with an in-depth understanding of how your plant works, what the key processes are, and what your growth plans are.
Step 2
High-level architecture design
We create a conceptual design for a new secure architecture, defining the main levels and security zones according to the Purdue model.
Step 3
Detailed segmentation design
We are working on a detailed plan for segmenting the network, defining zones, communication channels and firewall policies.
Step 4
Development of project documentation
You receive complete technical documentation of the new architecture, along with recommendations for the necessary hardware and software.
Step 5
Support in supervision of implementation
We can act as an authoring supervisor, supporting your integrators in the implementation of the new architecture to ensure compliance with the design.
What does your business gain? A foundation for years to come
Investing in a well-thought-out architecture is the most cost-effective decision in the entire life cycle of a system.
Stop building a flat network. Start creating real defensive zones.
