ITL’S USABILITY REPORTING DOCUMENT PROVES USEFUL TO INDUSTRY DEVELOPERS

The recently approved ANSI/INCITS standard, Common Industry Format (CIF) for Usability Test Reports, is already proving to be an effective vehicle for sharing information between software suppliers and customers. Development of the standard was coordinated with industry by our Information Access Division.

 

Several pilot studies have been conducted which verify the CIF’s usefulness in improving software design and procurement. By using the CIF, software suppliers have found a means to learn more about their customers’ requirements, which allows them to develop products better suited to their customers’ needs; this is expected to greatly reduce development time and result in more usable products. In addition, software consumers are learning more about the use of software in their own organizations and the financial benefits of improving usability by using the CIF. The initial focus of the pilot studies has been on software for upgrades, new software products, and custom applications. Our role in the pilot studies has been to act as a collection and dissemination agent and to facilitate sharing results from the pilot studies to refine the common usability reporting format and the associated metrics.

 

As a result of initial pilot studies, Oracle, a large supplier of database products, has standardized on the CIF for reporting usability tests within their company. The Boeing Desktop Standards Board voted to adopt the CIF as the Boeing standard for software product usability. Boeing product managers are encouraged to work proactively with suppliers to begin applying the CIF during the design stage of product development. The Boeing Company is an international manufacturing firm that is also a large consumer of software products. In the Oracle/Boeing pilot study, the CIF was used as a communication vehicle for exchanging user requirements and usability data over a one-year period. Based on the last CIF delivered by Oracle, Boeing was able to see that significant usability improvements had been made, resulting in estimates of thousands of dollars in database administrator productivity. Boeing used this information in making the decision to renew the Oracle license for future versions of database software, training, and support.

 

In another supplier-consumer pilot study, Microsoft and Boeing collaborated to compare the usability of beta releases of Windows 2000 and an earlier version of this operating system. The effort involved joint design of web-based survey tools for estimating the effects of improved product usability. These collected data were used to estimate reduction in the overhead that results when end-users encounter usability problems. There were improvements in successive beta versions and an improvement over the usability of older versions of Windows. Boeing used this data as input to a decision to upgrade desktop systems to Windows 2000.

 

Several European pilot studies have reported the successful use of CIF in usability requirements for a website, usability requirements for a desktop travel expense reporting system, assessment of a website for e-commerce, and assessment of travel management software.  

 

In addition to its application for software development and procurement, extensions to the CIF are currently being considered for reporting usability testing of hardware, evaluation of websites, universal accessibility, and as a means of documenting user requirements. The ANSI/INCITS-approved CIF standard is currently being proposed to the International Organization for Standardization (ISO), to become an international standard. The CIF has proven its utility to both of its targeted user groups -- usability professionals and corporate decision makers. The CIF was developed by the IUSR group, composed of human factors and software engineers in industry and academia and led by ITL. The ANSI/INCITS CIF standard can be obtained from ANSI or online from the NIST IUSR website http://www.nist.gov/iusr.

 

ITL Releases Updated Reference Data Set to Fight Computer Crime

We recently released an updated National Software Reference Library (NSRL) Reference Data Set to assist the law enforcement community in fighting crimes involving computers. The NSRL encompasses a repository of all types of software, including operating systems, vertical applications, database management systems, graphics packages, games, etc. It also includes a database of file profiles, i.e., software fingerprints, that can be used to identify known and unknown files on computers, diskettes, magnetic tapes, CDs, etc., that have been seized pursuant to investigation. Containing over 6 million file signatures, the data set is available at http://www.nist.gov/srd/nistsd28.htm.

 

The NSRL can save an investigator hundreds of hours in an investigation. A single computer or hard disk drive can contain between 10,000 and 50,000 individual files, each of which must be examined for probative value. If multiple computers, disk drives, magnetic tapes, or other media are involved, the staff hours could reach into the thousands and take months to finish. The NSRL reduces the time it takes to investigate each computer by 40 to 95 percent, depending on the contents of the file system. It allows the investigator to weed out files that have known profiles and fingerprints in ITL’s database. The investigator can then concentrate on the unknown files. ITL produces the NSRL using state-of-the-art software and computers to verify the fingerprints of each software package.

 

A collaboration of NIST, the National Institute of Justice (NIJ), the Federal Bureau of Investigation (FBI), the Defense Computer Forensics Laboratory (DCFL), the U.S. Customs Service, software vendors, and state and local law enforcement organizations, the NSRL is an example of the application of technology to investigate crimes involving computers, such as child pornography, racketeering, cyber-attacks, illegal gambling, Internet fraud, and software piracy.

 

ITL Publishes Smart Card Interoperability Specifications

The federal government is expanding smart card use among federal employees because of the security features and inherent versatility of smart cards. For example, a single smart card could be used as an identification card, to provide access to secure buildings, to securely logon to computer systems, and to make small purchases. However, the federal government has been reluctant to use smart cards on a large scale primarily due to the lack of interoperability among smart card products.

 

Scientists in our Computer Security Division have been working with the General Services Administration, other federal agencies, and industry partners for the past several years to establish a Government Smart Card (GSC) program to facilitate widespread deployment of interoperable smart card systems. Specifically, we set out to build a framework for smart card interoperability, enabling broad adoption of this critical technology by the public and private sectors. The mechanism and technical foundation for this framework is the Government Smart Card Interoperability Specification (GSC-IS). The GSC-IS version 2.0 was published on June 27, 2002 as NISTIR 6887.

 

The GSC-IS lays the groundwork for smart cards to work in an open environment. It defines an architectural model for interoperable smart card service provider modules, compatible with both file system cards and virtual machine cards, that allows smart card application developers to obtain various services (e.g., encryption, authentication, digital signatures, etc.) from GSC-compliant smart cards through a common, interoperable smart card services interface. We have begun introducing the specification into the national and international voluntary standards arena.

 

The GSC-ISv2.0 is available as NISTIR 6887 at http://smartcard.nist.gov.
