Rockwell Automation has published Security Advisory SD1771 to share customer-facing guidance and recommended actions for reducing exposure and strengthening the security of Rockwell controller environments. For the most accurate, up-to-date details, reference Rockwell’s Security Advisory SD1771¹ directly.

Rockwell’s Recommended Immediate Actions

Ensure controllers are not exposed to the public internet.
Ensure security protections are enabled on controllers.
Use a defense-in-depth strategy to segment and protect operational technology (OT) assets.
Where applicable, place the controller’s mode switch into “Run” and store project files offline for disaster recovery.

OT Cybersecurity or IT Security — Who Should Review SD1771?

Most organizations get the best outcomes when SD1771 is reviewed by both OT/controls stakeholders and IT/security stakeholders. OT/controls stakeholders may include a combination of plant engineering, controls/automation and operations resources. IT/security stakeholders are typically network/security, incident response and vulnerability management teams. If you are unsure who owns OT cybersecurity versus IT security, a simple first step is to share the official SD1771 link with both groups and align on ownership and next actions.

Why This Matters for OT Cybersecurity

OT environments are increasingly connected, and security decisions often require coordination across operations, engineering and IT. A U.S. government joint cybersecurity advisory² reinforces the importance of reducing exposure for internet-facing OT devices and implementing mitigations to reduce compromise risk.

Wesco’s Knowledge Hub resources emphasize the importance of visibility, resilience and practical security strategies tailored to industrial networks — especially as OT and IT converge.

How Wesco Can Help

Wesco offers plant floor health checks — facility assessments and preventative/predictive services that help manufacturers understand the overall health of the plant floor. These health checks are conducted by Wesco specialists who examine security, assets, operations and processes, proactively identifying risks and areas for improvement before equipment malfunction or failure occurs.

With regular plant floor health checks, facilities can help ensure security, safety and regulatory compliance; maximize overall equipment effectiveness (OEE); reduce unplanned downtime; and optimize their installed base investment. Within plant floor health checks, Wesco specifically calls out networking and cybersecurity assessments that provide insight into potential security risks, key network issues and opportunities for improvement.

If your team is reviewing the SD1771 and would like help organizing next steps, Wesco can support you through a plant floor network health check as part of our plant floor health check program.
