Enabling the Internet White Pages Service -- the Directory Guardian

The Internet White Pages Service (IWPS) has been slow to materialise for many reasons. One of them is the security concerns that organisations have, over allowing the public to gain access to either their Intranet or their directory database. The Directory Guardian is a firewall application proxy for X.500 and LDAP protocols that is designed to alleviate these fears. Sitting in the firewall system, it filters directory protocol messages passing into and out of the Intranet, allowing security administrators to carefully control the amount of directory information that is released to the outside world. This paper describes the design of our Guardian system, and shows how relatively easy it is to configure its filtering capabilities. Finally the paper describes the working demonstration of the Guardian that was built for the 1997 World Electronic Messaging Association directory challenge. This linked the WEMA directory to the NameFLOWParadise Internet directory, and demonstrated some of the powerful filtering capabilities of the Guardian

The National Directory of New Hires

[Excerpt] The National Directory of New Hires is a database that contains personal and financial data on nearly every working American, as well as those receiving unemployment compensation. Contrary to its name, the National Directory of New Hires includes more than just information on new employees. It is a database that includes information on (1) all newly hired employees, compiled from state reports (and reports from federal employers), (2) the quarterly wage reports of existing employees (in Unemployment Compensation (UC)-covered employment), and (3) unemployment compensation claims. The National Directory of New Hires was originally established to help states locate noncustodial parents living in a different state so that child support payments could be withheld from that parent’s paycheck. Since its enactment in 1996, the National Directory of New Hires has been extended to several additional programs and agencies to verify program eligibility, prevent or end fraud, collect overpayments, or assure that program benefits are correct. Although the directory is considered very effective, concerns about data security and the privacy rights of employees remain a part of debates regarding expanded access to the National Directory of New Hires

Secure Directories

This paper describes the mechanisms that are needed in order to provide a secure directory service based on the X.500 data model. A brief introduction to the X.500 data model is given followed by an overview of the Lightweight Directory Access Protocol. Security can be provided by three functions: an application level firewall, an authentication mechanism, and an access control scheme. A description of the X.500 and LDAP access control models is presented followed by the authentication methods that have been standardised for LDAPv3. A companion paper describes a directory application firewall

VIPS: simple, efficient, and scalable cache coherence

Directory-based cache coherence is the de-facto standard for scalable shared-memory multi/many-cores and significant effort is invested in reducing its overhead. However, directory area and complexity optimizations are often antithetical to each other. This talk presents VIPS, a family of cache coherence protocols based on self-invalidation and self-downgrade. VIPS protocols remove the complexity and cost associated with directories in their entirety, thus increasing multiprocessors scalability, and at the same time, provide better performance and energy efficiency than traditional directory-based protocols

Directory of Water Related Courses Offered at Colleges and Universities in Arkansas as of November 1998

This publication lists the water and water-related courses at several universities and colleges in Arkansas as reported during the Fall of 1 998. It is anticipated that users of this directory will extend beyond college students, and will include professionals seeking continuing education, and professors desiring to exchange Information on courses. This directory is not an absolute source of water and water-related courses because all of the higher learning Institutions In Arkansas are not listed, and, secondly, because the definition of water and water-related varies from institution to institution. None-the-less this directory provides a very valuable and impressive reference on water resources courses. Users must remember that course offerings, titles, and content change; therefore, one must contact the department to confirm details about each course. We are very grateful to the many people, too numerous to list, who have cooperated in gathering the Information In this second edition of the directory

Buffalo Arts and Culture Organizations

Open Buffalo and Partnership for the Public Good collaboratively compiled a directory of organizations that promote social justice through locally based arts and cultural programmatic efforts. This directory has contact information, as well as the mission and social justice commitment of the various organizations

Toward an Interactive Directory for Norfolk, Nebraska: 1899-1900

We describe steps toward an interactive directory for the town of Norfolk, Nebraska for the years 1899 and 1900. This directory would extend the traditional city directory by including a wider range of entities being described, much richer information about the entities mentioned and linkages to mentions of the entities in material such as digitized historical newspapers. Such a directory would be useful to readers who browse the historical newspapers by providing structured summaries of the entities mentioned. We describe the occurrence of entities in two years of the Norfolk Weekly News, focusing on several individuals to better understand the types of information which can be gleaned from historical newspapers and other historical materials. We also describe a prototype program which coordinates information about entities from the traditional city directories, the federal census, and from newspapers. We discuss the structured coding for these entities, noting that richer coding would increasingly include descriptions of events and scenarios. We propose that rich content about individuals and communities could eventually be modeled with agents and woven into historical narratives
