NIST Issues Expanded Draft of Smart Grid Cyber Security Strategy For Public Review and Comment
Last updated: November 29, 2010 - 11:33am
On February 3, the Commerce Department's National Institute of Standards and Technology (NIST) issued the second draft of its Smart Grid Cyber Security Strategy and Requirements, which now identifies more than 120 interfaces that will link diverse devices, systems and organizations engaged in two-way flows of electricity and information and classifies these connections according to the level of damage that could result from a security breach.
Prepared by the NIST-led Cyber Security Working Group, which has more than 350 members, the new draft report expands upon an earlier preliminary version, which was released by Commerce Secretary Gary Locke last September and underwent 60 days of public review. It incorporates responses to the more than 350 individual comments received. The updated draft also includes new or more detailed technical inputs stemming from the working group's continuing assessment of what will be required to ensure the security and reliability of the entire modernized power system and to protect the integrity and confidentiality of information exchanged during energy-related transactions on the Smart Grid. The 300-page second draft of the Smart Grid cyber security document also will undergo public review, ending on April 2, 2010. After reviewing the comments received and completing ongoing analyses of requirements and relevant standards, the working group will finalize the Smart Grid cyber security strategy.
NIST expects to issue a completed report by early summer. Compared with the initial version, the draft cyber security report issued today contains significantly expanded sections on privacy, vulnerability categories, analyses of the potential security issues, and the overall approach to achieving Smart Grid cyber security. The new draft classifies Smart Grid interfaces according to the level of impact—or scale and scope of damage—that could result from a compromise in security. Security requirements are established for multiple logical interface categories of the Smart Grid. In all, the new draft identifies more than 120 interfaces that pertain to high-priority Smart Grid applications, including electric transportation, electric storage, advanced metering infrastructure, distribution grid management, energy management in homes and businesses, and grid management.
