Secure Critical Infrastructures
With CYBERSEC.
Comprehensive Network and Security Solutions for Cyber-Physical Systems
Cybersecurity for Operational Technology
The convergence of operational technology (OT) and information technology (IT) networks impacts the security of industrial control systems (ICS) and supervisory control and data acquisition (SCADA) systems. By designing security into complex infrastructure via the OT-Aware CYBERSEC Security Fabric, OT organizations have an efficient, non-disruptive way to ensure that the OT environment is protected and compliant.
2023 The State of Operational Technology and Cybersecurity
Protecting OT systems is now more critical than ever as more organizations connect their OT environments to the internet. Although IT/OT convergence has many benefits, it is being hampered and handicapped by advanced and destructive cyberthreats. The spillover of these attacks is increasingly targeted at OT environments.
CYBERSEC Security Fabric for OT Environments
The Fortinet Security Fabric seamlessly enables security for converged IT/OT ecosystems. It provides OT-centric features and products to extend Security-Fabric capabilities to OT networks. To alleviate security risks across the organization, Fortinet has enhanced the OT security offerings. The innovations range from edge products to NOC/SOC tools and services to ensure efficient performance.
Challenges
CYBERSEC's ICS/SCADA Solution

The Purdue Model
CYBERSEC uses the Purdue Model as a reference network architecture to differentiate between IT and OT solutions. Fortunately, for customers seeking vendor consolidation and IT/OT convergence, the Fortinet IT Security Fabric and the Fortinet OT-Aware Security Fabric enable seamless network and security operations between both IT and OT. Below is a breakdown of the CYBERSEC products and services that protect both IT and OT.

Cloud & External Zones
The Internet/WAN Zone delivers access to cloud-based services for compute and analytics to support ERP and MRP systems for an operational environment. For strong authentication, two-factor authentication and VPN tunnels are used to verify identity and keep data private.
Business & Enterprise Zones
The enterprise zone typically sits at the corporate level and spans multiple facilities, locations, or plants where the business systems work to perform operational tasks and includes an IT network and security operations center (IT NOC/SOC).
Between the enterprise and site operations zones is the Converged IT & OT zone, what is known as the Demilitarized Zone (DMZ). The DMZ allows the organization to securely connect networks with different security requirements. Security protection includes authentication and business segmentation to provide visibility, control and situational awareness to manage against known and unknown threats. Verify who and what is on the network, and provide role-based access control for users, devices, applications, and protocols. Address unknown threats with sandboxing and deception detection as well as provide industrial security information to the NOC/SOC.


Operations & Control Zones
Site Operations enables the centralized control and monitoring of all the systems that run the processes in a facility. This is where OT systems share data with IT systems. CYBERSEC next-generation firewall appliances are frequently deployed here for top-rated protection and segmentation, providing visibility and control.

Process Control Zones
The Industrial Zone is where the production takes place. This zone includes digital control elements like PLCs and RTUs that convert IP communication to serial commands, including additional networks such as networks to support IoT devices.
