May 15, 2013
NIST announces the release of Special Publication 800-82, Revision 1, Guide to Industrial Control System (ICS) Security. Special Publication 800-82 provides guidance on how to improve the security in Industrial Control Systems (ICS), including Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), and other control system configurations such as Programmable Logic Controllers (PLC), while addressing unique performance, reliability, and safety requirements. Special Publication 800-82: (i) provides an overview of ICS and typical system topologies; (ii) identifies typical threats to organizational missions and business functions supported by ICS; (iii) describes typical vulnerabilities in ICS; and (iv) provides recommended security controls (i.e., safeguards and countermeasures) to respond to the associated risks.
Special Publication 800-82, Revision 1 includes the ICS material transferred from Special Publication 800-53, Revision 3, Recommended Security Controls for Federal Information Systems and Organizations, Appendix I. Special Publication 800-82, Revision 1 is being released concurrent with Special Publication 800-53, Revision 4, Security and Privacy Controls for Federal Information Systems and Organizations, to preserve the continuity of that ICS material. The ICS material is now located in Appendix G of Special Publication 800-82, Revision 1.
Additionally, NIST is planning a major update to Special Publication 800-82 (Special Publication 800-82, Revision 2) that will include:
- Updates to ICS threats and vulnerabilities;
- Updates to ICS risk management, recommended practices and architectures;
- Updates to current activities in ICS security;
- Updates to security capabilities and technologies for ICS;
- Additional alignment with other ICS security standards and guidelines;

NIST Announces the Final Release of SP 800-53 Revision 4, Security and Privacy Controls for Federal Information Systems and Organizations
April 30, 2013
NIST announces the final release of Special Publication (SP) 800-53, Revision 4, Security and Privacy Controls for Federal Information Systems and Organizations. Special Publication 800-53, Revision 4, represents the most comprehensive update to the security controls catalog since its inception in 2005. The publication was developed by NIST, the Department of Defense, the Intelligence Community, and the Committee on National Security Systems as part of the Joint Task Force, an interagency partnership formed in 2009. This update was motivated principally by the expanding threat space—characterized by the increasing sophistication of cyber attacks and the operations tempo of adversaries (i.e., the frequency of such attacks, the professionalism of the attackers, and the persistence of targeting by attackers). State-of-the-practice security controls and control enhancements have been developed and integrated into the catalog addressing such areas as: mobile and cloud computing; applications security; trustworthiness, assurance, and resiliency of information systems; insider threat; supply chain security; and the advanced persistent threat. In addition, Special Publication 800-53 has been expanded to include eight new families of privacy controls based on the internationally accepted Fair Information Practice Principles.
Special Publication 800-53, Revision 4, provides a more holistic approach to information security and risk management by providing organizations with the breadth and depth of security controls necessary to fundamentally strengthen their information systems and the environments in which those systems operate—contributing to systems that are more resilient in the face of cyber attacks and other threats. This "Build It Right" strategy is coupled with a variety of security controls for "Continuous Monitoring" to give organizations near real-time information that is essential for senior leaders making ongoing risk-based decisions affecting their critical missions and business functions.
To take advantage of the expanded set of security and privacy controls, and to give organizations greater flexibility and agility in defending their information systems, the concept of overlays was introduced in this revision. Overlays provide a structured approach to help organizations tailor security control baselines and develop specialized security plans that can be applied to specific missions/business functions, environments of operation, and/or technologies. This specialization approach is important as the number of threat-driven controls and control enhancements in the catalog increases and organizations develop risk management strategies to address their specific protection needs within defined risk tolerances.
Finally, there have been several new features added to this revision to facilitate ease of use by organizations. These include:
- Assumptions relating to security control baseline development;
- Expanded, updated, and streamlined tailoring guidance;
- Additional assignment and selection statement options for security and privacy controls;
- Descriptive names for security and privacy control enhancements;
- Consolidated tables for security controls and control enhancements by family with baseline allocations;
- Tables for security controls that support development, evaluation, and operational assurance; and
- Mapping tables for international security standard ISO/IEC 15408 (Common Criteria).
The security and privacy controls in Special Publication 800-53, Revision 4, have been designed to be largely policy/technology-neutral to facilitate flexibility in implementation. The controls are well positioned to support the integration of information security and privacy into organizational processes including enterprise architecture, systems engineering, system development life cycle, and acquisition/procurement. Successful integration of security and privacy controls into ongoing organizational processes will demonstrate a greater maturity of security and privacy programs and provide a tighter coupling of security and privacy investments to core organizational missions and business functions.
Special Publication 800-53 Revision 4 is available here. A markup version of Appendices D, F, and G containing security control and security control baseline changes from SP 800-53, Revision 3 to Revision 4 will be available NLT May 7, 2013. There will be additional download instructions for the markup appendices provided by a subsequent notification from the FISMA Implementation Project.
An updated (April 30, 2013) FISMA Implementation Project Schedule is available at: http://csrc.nist.gov/groups/SMA/fisma/schedule.html.

Draft Special Publication 800-162, Guide to Attribute Based Access Control (ABAC) Definition and Considerations
April 22, 2013
NIST announces the public comment release of draft Special Publication (SP) 800-162, Guide to Attribute Based Access Control (ABAC) Definition and Considerations. ABAC is a logical access control methodology where authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases, environment conditions against policy, rules, or relationships that describe the allowable operations for a given set of attributes. This document provides Federal agencies with a definition of ABAC and considerations for using ABAC to improve information sharing within organizations and between organizations while maintaining control of that information.
NIST requests comments on draft SP 800-162 by May 31, 2013. Please send comments to vincent.hu@nist.gov with the subject "Comments SP 800-162"

Final Public Draft of NIST Special Publication 800-53 Revision 4
February 5, 2013
NIST announces the release of Draft Special Publication 800-53, Revision 4, Security and Privacy Controls for Federal information Systems and Organizations (Final Public Draft). Special Publication 800-53, Revision 4, represents the culmination of a two-year initiative to update the guidance for the selection and specification of security controls for federal information systems and organizations. This update, the most comprehensive since the initial publication of the controls catalog in 2005, was conducted as part of the Joint Task Force Transformation Initiative in cooperation and collaboration with the Department of Defense, the Intelligence Community, and the Committee on National Security Systems. NIST received and responded to several thousand comments during the extensive public review and comment period.
The proposed changes included in Special Publication 800-53, Revision 4, support the federal information security strategy of “Build It Right, Then Continuously Monitor” and are directly linked to the current threat space (i.e., capabilities, intentions, and targeting of adversaries) as well as the attack data collected and analyzed over a substantial period of time. In this update, there is renewed emphasis on security controls that can be implemented to increase the reliability, trustworthiness, and resiliency of information systems, system components, and information system services—especially in those systems, components, and services supporting critical organizational missions and business operations (including, for example, critical infrastructure applications). In particular, the major changes in Revision 4 include:
- New security controls and control enhancements addressing the advanced persistent threat (APT), supply chain, insider threat, application security, distributed systems, mobile and cloud computing, and developmental and operational assurance;
- Clarification of security control language;
- New tailoring guidance including the fundamental assumptions used to develop the security control baselines;
- Significant expansion of supplemental guidance for security controls and enhancements;
- Streamlined tailoring guidance to facilitate customization of baseline security controls;
- New privacy controls and implementation guidance based on the internationally recognized Fair Information Practice Principles;
- Updated security control baselines;
- New summary tables for security controls and naming convention for control enhancements to facilitate ease-of-use;
- New mapping tables for ISO/IEC 15408 (Common Criteria);
- The concept of overlays, allowing organizations and communities of interest to develop specialized security plans that reflect specific missions/business functions, environments of operation, and information technologies; and
- Designation of assurance-related controls for low-impact, moderate-impact, and high-impact information systems and additional controls for responding to high assurance requirements.
To support the final public review process, NIST will publish a markup version of Appendices D, F, and G (i.e., baseline allocations and the catalog of security controls for information systems and organizations) on or about February 8th to show the changes from the initial public draft. This will help organizations plan for any future update actions they may wish to undertake after Revision 4 is finalized. There will not be any markups provided for the main chapters or other appendices. A markup showing changes from Revision 3 to Revision 4 for the aforementioned appendices will be provided upon final publication of Special Publication 800-53, anticipated for April 2013.
Public comment period: February 5th through March 1st, 2013.

DRAFT Special Publication 800-63-2, Electronic Authentication Guideline is now available for comment
February 1, 2013
NIST announces the release of Draft Special Publication 800-63-2, Electronic Authentication Guideline for public review and comment. This recommendation provides technical guidelines for Federal agencies implementing electronic authentication and is not intended to constrain the development or use of standards outside of this purpose. The recommendation covers remote authentication of users (such as employees, contractors, or private individuals) interacting with government IT systems over open networks. It defines technical requirements for each of four levels of assurance in the areas of identity proofing, registration, tokens, management processes, authentication protocols and related assertions. This publication will supersede NIST Special Publication 800-63-1.
This draft is a limited update of Special Publication 800-63-1 and substantive changes are made only in section 5. Registration and Issuance Processes. The substantive changes in the revised draft are intended to facilitate the use of professional credentials in the identity proofing process, and to reduce the need to use postal mail to an address of record to issue credentials for level 3 remote registration. Other changes to section 5 are minor explanations and clarifications. New or revised text is highlighted in the review draft. Other sections of NIST Special Publication 800-63-1 have not been changed in this draft.
Please submit comments on the revision to eauth-comments@nist.gov with the subject line: “Draft SP 800-63-2 Comments”. The comment period closes on March 4, 2013.
