OT Cybersecurity Best Practices for SMBs: How to Implement Change Management
Summary: Dragos OT-CERT published a monthly best-practices blog for under-resourced organizations on implementing a change management process for ICS/OT environments, covering a change management tracker with fields for a unique change identifier, a named Change Manager, affected systems, stakeholder notification, test pass/fail, production pass/fail, and date of completion. The post states a change is complete only when implementation, operational testing, and evidence collection for regulatory or business compliance are finished and the environment is stable, and it offers a downloadable tracker template on the OT-CERT portal.
What's compelling: The post defines completion narrowly: not the date a change is pushed to systems, but the day testing is done, results are shared with stakeholders, and the environment is stable - a bar many OT teams quietly skip under production pressure.
