OT Cybersecurity Best Practices for SMBs: System Hardening for an OT Environment

Summary: Dragos OT-CERT published a monthly best-practices blog on system hardening for operational technology environments, aimed at small and medium businesses and under-resourced organizations that lack in-house security expertise. The post recommends testing and validating operations before any hardening procedure is applied in production, points readers to an ICS/OT Security Hardening Checklist for tracking status, and offers free OT-CERT membership with reports, webinars, training, assessments, toolkits, and tabletop exercises.

Bottom line: The post asks whether your risk assessment covers a cyber attack on a critical supplier and whether you could still produce your product or serve customers if one were hit - a question SMBs with OT environments and no dedicated security staff are least equipped to answer.
