Will deploying these firewall rules disrupt my industrial process?

The skill follows best practices for OT environments, emphasizing transparent inline bridge mode and fail-open configurations to ensure that security enforcement does not compromise process availability.

Can this skill help with IEC 62443 compliance?

Yes, it specifically facilitates the implementation of zone and conduit requirements as defined in the IEC 62443 industrial cybersecurity standards.

Does this skill require specific hardware?

Yes, it is designed to configure Tofino Xenon physical appliances or virtual appliances from Belden/Hirschmann within an industrial environment.

Which industrial protocols does this Tofino skill support?

It supports Deep Packet Inspection (DPI) for Modbus TCP, S7comm (Siemens), EtherNet/IP (Rockwell), and OPC, allowing for fine-grained control over specific function codes and operations.

Security & Testing

Deploys and configures Tofino industrial firewalls to secure SCADA systems and PLCs using protocol-aware deep packet inspection.

This skill enables automated configuration and deployment of Tofino Xenon industrial firewalls to protect critical infrastructure assets. It provides a structured approach to implementing IEC 62443 zone and conduit boundaries by applying deep packet inspection (DPI) to OT protocols such as Modbus, S7comm, and EtherNet/IP. By leveraging this skill, security teams can enforce granular access control between industrial security zones, provide compensating controls for legacy PLCs, and maintain process availability through fail-open configurations without disrupting existing communications.
