ITL Publishes Security and Privacy Controls for Federal Agencies

May 1, 2013
Author(s)
Elizabeth B. Lennon
This ITL Bulletin for May 2013 announces the publication of NIST Special Publication 800-53, Revision 4, Security and Privacy Controls for Federal Information Systems and Organizations. Developed by the Joint Task Force Transformation Initiative

Logic Minimization Techniques with Applications to Cryptology

April 1, 2013
Author(s)
Joan Boyar, Philip Matthews, Rene Peralta
A new technique for combinational logic optimization is described. The technique is a two-step process. In the rst step, the non-linearity of a circuit as measured by the number of non-linear gates it contains is reduced. The second step reduces the number

Combinatorial Coverage Measurement Concepts and Applications

March 22, 2013
Author(s)
David R. Kuhn, Itzel (. Dominquez Mendoza, Raghu N. Kacker, Yu Lei
Empirical data demonstrate the value of t-way coverage, but in some testing situations, it is not practical to use covering arrays. However any set of tests covers at least some proportion of t-way combinations. This paper describes a variety of measures

Security Assurance Requirements for Hypervisor Deployment Features

February 24, 2013
Author(s)
Ramaswamy Chandramouli
Virtualized hosts provide abstraction of the hardware resources (i.e., CPU, Memory etc) enabling multiple computing stacks to be run on a single physical machine. The Hypervisor is the core software that enables this virtualization and hence must be

Report on the Static Analysis Tool Exposition (SATE) IV

February 4, 2013
Author(s)
Vadim Okun, Aurelien M. Delaitre, Paul E. Black
The NIST SAMATE project conducted the fourth Static Analysis Tool Exposition (SATE IV) to advance research in static analysis tools that find security defects in source code. The main goals of SATE were to enable empirical research based on large test sets

Mapping Evidence Graphs to Attack Graphs

January 17, 2013
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Attack graphs compute potential attack paths from a system configuration and known vulnerabilities of a system. Evidence graphs model intrusion evidence and dependencies among them for forensic analysis. In this paper, we show how to map evidence graphs to

Using Attack Graphs in Forensic Examinations

January 16, 2013
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
Attack graphs are used to compute potential attack paths from a system configuration and known vulnerabilities of a system. Attack graphs can be used to eliminate known vulnerability sequences that can be eliminated to make attacks difficult and help

Summary of the Workshop on Cryptographic Key Management Systems (CKMS)

January 10, 2013
Author(s)
Elaine B. Barker, Miles Smid, Dennis Branstad
A workshop was held on September 10-11, 2012 to discuss two documents that have been posted for public comment: SP 800-130 (A Framework for Designing Cryptographic Key Management Systems) and a table of proposed requirements for SP 800-152 (A Profile for U

Recommendation for Cryptographic Key Generation

December 21, 2012
Author(s)
Elaine B. Barker, Allen L. Roginsky
Cryptography is often used in an information technology security environment to protect data that is sensitive, has a high value, or is vulnerable to unauthorized disclosure or undetected modification during transmission or while in storage. Cryptography

Introducing the Federal Cybersecurity R&D Strategic Plan

In December 2011, the White House Office of Science and Technology Policy (OSTP) released the Trustworthy Cyberspace: Strategic Plan for the Federal Cybersecurity Research and Development Program - a framework for a set of coordinated Federal strategic

Securing Americas Digital Infrastructure Through Education

December 14, 2012
Author(s)
William D. Newhouse
This article provides an overview of the establishment of the National Initiative for Cybersecurity Education (NICE), its government structure, and it goals. Parallels are drawn between the strategic R&D thrust, Developing Scientific Foundations, described

Security Ontologies for Modeling Enterprise Level Risk Assessment

December 7, 2012
Author(s)
Anoop Singhal, Samuel Singapogu
A unified formal knowledge model of information security domain is essential to support a risk management approach. IT Applications are increasingly exposed to a variety of information security threats. Often wrong decisions are made due to insufficient

Protecting Wireless Local Area Networks

December 3, 2012
Author(s)
Shirley M. Radack, David R. Kuhn
This article summarizes the information that was presented in the February 2012 Information Technology Laboratory (ITL) bulletin, Guidelines for Securing Wireless Local Area Networks (WLANs). The bulletin, which was noted by WERB in February 2012, was

A Credential Reliability and Revocation Model for Federated Identities

November 29, 2012
Author(s)
Hildegard Ferraiolo
A large number of Identity Management Systems (IDMSs) are being deployed worldwide that use different technologies for the population of their users. With the diverse set of technologies, and the unique business requirements for organizations to federate
