A Resiliency Supplement to NISTIR 7628 rev. 1 – Cybersecurity Guidelines for the Smart Grid Identifies best practices for cyber-physical resilience Pays special attention to interaction between cyber and physical components Focuses on grid hardening techniques Building resiliency into cybersecurity The smart grid not only needs sound architecture for functionality, and cybersecurity for security — it also needs resilience to satisfy its high operational availability requirements. This resilience refers to the ability for the physical architecture to continue, or quickly recover to normal operation after a cyber event. The systems need additional requirements to include resiliency measures to expand on existing best practices and tools. Based on the National Institute of Standards and Technology Interagency Report 7628 Revision.1 (NISTIR 7628 rev1), the SEPA Cyber-Physical Resiliency Task Force has identified resiliency gaps that exist. The task force then created a “crosswalk” between the NISTIR 7628 rev1 and other available resiliency controls. The final product here is a supplement of recommendations that acts as a resiliency gap filler to the NISTIR 7628 rev1. The Cyber-Physical Resilience Task Force is sponsored by both the SEPA Cybersecurity Working Group and the Grid Architecture Working Group.
