New guidance for operational technology (OT) aims to create a comprehensive ‘definitive record’ of OT environments to improve cybersecurity. This includes documenting system components, connectivity, architecture, supply chain access, and potential impacts of failures. Effective cybersecurity relies on visibility and management of sensitive information. The guidance, produced with international partners, encourages collaboration in maintaining updated records for informed decision-making.
