The staff of the Office of Energy Projects (OEP) has revised Section 9.0 of its Security Program for Hydropower Guidance (Guidance) to modernize the Commission's existing guidance for cybersecurity practices at licensed projects. The Section 9.0 revisions
reflect technological advancements and lessons learned through recent inspections and audits. The revised Section 9.0 Guidance updates definitions, applicability criteria, and the technical measures used to evaluate and protect cyber and control-system

of cybersecurity practices. The more specific your comments, the more useful they will be. Please note that this comment period
