The comment period will be open from October 25 through December 23, 2013. Draft NISTIR 7628 Rev. 1 was completed by the NIST-led Smart Grid Cybersecurity Committee (formerly the Cyber Security Working Group) of the Smart Grid Interoperability Panel. The document has been updated to address changes in technologies and implementations since the release of NISTIR 7628 in September 2010. In addition, the document development strategy, cryptography and key management, privacy, vulnerability classes, research and development topics, standards review, and key power system use cases have been updated and expanded to reflect changes in the Smart Grid environment since 2010. The final version is expected to be posted in the spring of 2014. Below are 6 links - the first 3 are for the NISTIR 7628 Rev. 1 which are broken down into 3 separate files (Volume 1, Volume 2, and Volume 3 in that order).

Such identification is not intended to imply recommendation or endorsement by NIST, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available for the purpose. There may be references in this publication to other publications currently under development by NIST in accordance with its assigned statutory responsibilities. The information in this publication, including concepts and methodologies, may be used by Federal agencies even before the completion of such companion publications. Thus, until each publication is completed, current requirements, guidelines, and procedures, where they exist, remain operative. For planning and transition purposes, Federal agencies may wish to closely follow the development of these new publications by NIST.

ITL develops tests, test methods, reference data, proof of concept implementations, and technical analyses to advance the development and productive use of information technology. ITL’s responsibilities include the development of management, administrative, technical, and physical standards and guidelines for the cost-effective security and privacy of other than national security-related information in Federal information systems. Abstract This three-volume report, Guidelines for Smart Grid Cybersecurity, presents an analytical framework that organizations can use to develop effective cybersecurity strategies tailored to their particular combinations of Smart Grid-related characteristics, risks, and vulnerabilities. Organizations in the diverse community of Smart Grid stakeholders—from utilities to providers of energy management services to manufacturers of electric vehicles and charging stations— can use the methods and supporting information presented in this report as guidance for assessing risk and identifying and applying appropriate security requirements. This approach recognizes that the electric grid is changing from a relatively closed system to a complex, highly interconnected environment. Each organization’s cybersecurity requirements should evolve as technology advances and as threats to grid security inevitably multiply and diversify. Keywords advanced metering infrastructure; architecture; cryptography; cybersecurity; electric grid; privacy; security requirements; smart grid ACKNOWLEDGMENTS This revision to the NISTIR was developed by members of the Smart Grid Interoperability Panel (SGIP) Smart Grid Cybersecurity Committee (SGCC) (formerly the Cyber Security Working Group (CSWG)), which is chaired by Marianne Swanson (NIST). Dave Dalva (Stroz Friedberg), Akhlesh Kaushiva (Department of Energy), and Scott Saunders (Sacramento Municipal Utility District) are the vice chairs and Mark Enstrom (Neustar) and Amanda Stallings (Ohio PUC) have served as the secretary. Tanya Brewer of NIST is the lead editor of this report. A special note of thanks goes to the subgroup leads, Frances Cleveland (Xanthus Consulting International), Victoria Pillitteri and Nelson Hastings (NIST), Rebecca Herold (Rebecca Herold & Associates, LLC), Elizabeth Sisley (Calm Sunrise Consulting, LLC), and Doug McGinnis (Exelon) who along with their subgroup team members contributed significantly to this revision. The dedication and commitment of all the individuals in developing the original document and now this revision is significant. In addition, appreciation is extended to the various organizations that have committed these resources to supporting this endeavor. Past and current members of the CSWG are listed in Appendix J of this report. Acknowledgement is also extended to the NIST Smart Grid Team and to Liz Lennon (NIST) for her superb technical editing of this report. Thanks is also extended to Bruce McMillin (Missouri University of Science and Technology), and to Harold Booth and Quynh Dang (NIST) for assistance in updating specific sections in the document. Finally, acknowledgment is extended to all the other individuals who have contributed their time and knowledge to ensure this report addresses the security needs of the Smart Grid.

  • The File Cmfonts.Fdd for Use with Latex2ε
    The file cmfonts.fdd for use with LATEX 2".∗ Frank Mittelbach Rainer Sch¨opf 2019/12/16 This file is maintained byA theLTEX Project team. Bug reports can be opened (category latex) at https://latex-project.org/bugs.html. 1 Introduction This file contains the external font information needed to load the Computer Modern fonts designed by Don Knuth and distributed with TEX. From this file all .fd files (font definition files) for the Computer Modern fonts, both with old encoding (OT1) and Cork encoding (T1) are generated. The Cork encoded fonts are known under the name ec fonts. 2 Customization If you plan to install the AMS font package or if you have it already installed, please note that within this package there are additional sizes of the Computer Modern symbol and math italic fonts. With the release of LATEX 2", these AMS `extracm' fonts have been included in the LATEX font set. Therefore, the math .fd files produced here assume the presence of these AMS extensions. For text fonts in T1 encoding, the directive new selects the new (version 1.2) DC fonts. For the text fonts in OT1 and U encoding, the optional docstrip directive ori selects a conservatively generated set of font definition files, which means that only the basic font sizes coming with an old LATEX 2.09 installation are included into the \DeclareFontShape commands. However, on many installations, people have added missing sizes by scaling up or down available Metafont sources. For example, the Computer Modern Roman italic font cmti is only available in the sizes 7, 8, 9, and 10pt.

Such an equalizer for the other 10GBASE-R PHYs? needs to be excluded from the ability to claim compliance to the standard, or the standard Suggested Remedy is broken. A dynamic receiver test is required. Add LWM or perhaps add a brief statement that the Clause 68 PMD does not support WIS. Suggested Remedy Add a dynamic test for the receiver. The suggested way to achieve such a test is based Response Response Status O upon the block diagram in Figure 68-10.
