Introduction Four global networks carry most of the Computer networking is widespread, supported by international network traffic; FidoNet, UUCP, the global Matrix of interconnected computer BITNET, and the Internet. The first step in networks such as the Internet, BITNET, UUCP, looking at these networks involves collecting and FidoNet. Perhaps 20,000,000 people use this appropriate data for each and performing some global Matrix of computer networks, and several consistency checking. The data for these maps major global computer networks are growing was initially derived from their node lists exponentially, rapidly reaching new countries and (BITNET and FidoNet) or host lists (UUCP).

Telecommunications Infrastructure for Electronic Delivery 3
Telecommunications Infrastructure for Electronic Delivery 3 SUMMARY The telecommunications infrastructure is vitally important to electronic delivery of Federal services because most of these services must, at some point, traverse the infrastructure. This infrastructure includes, among other components, the Federal Government’s long-distance telecommunications program (known as FTS2000 and operated under contract with commercial vendors), and computer networks such as the Internet. The tele- communications infrastructure can facilitate or inhibit many op- portunities in electronic service delivery. The role of the telecommunications infrastructure in electronic service delivery has not been defined, however. OTA identified four areas that warrant attention in clarifying the role of telecommunications. First, Congress and the administration could review and update the mission of FTS2000 and its follow-on contract in the context of electronic service delivery. The overall perform- ance of FTS2000 shows significant improvement over the pre- vious system, at least for basic telephone service. FTS2000 warrants continual review and monitoring, however, to assure that it is the best program to manage Federal telecommunications into the next century when electronic delivery of Federal services likely will be commonplace. Further studies and experiments are needed to properly evaluate the benefits and costs of FTS2000 follow-on options from the perspective of different sized agencies (small to large), diverse Federal programs and recipients, and the government as a whole. Planning for the follow-on contract to FTS2000 could consider new or revised contracting arrangements that were not feasible when FTS2000 was conceived. An “overlapping vendor” ap- proach to contracting, as one example, may provide a “win-win” 57 58 I Making Government Work situation for all parties and eliminate future de- national infrastructure will be much stronger if bates about mandatory use and service upgrades. -

Fifty-four librarians completed the questionnaire, which sought information on the computer conferences to which they subscribed; the length of time they had been using either BITNET or the Internet; and the type of training they had had in using either of the two networks. In addition, the respondents were asked to rank five functions or capabilities available on either BITNET or Internet--electronic mail and computer forums, remote database searching, file transiur and data exchange, research and publication on the Internet--by extent of use. -

Trojans and Malware on the Internet an Update
Attitude Adjustment: Trojans and Malware on the Internet An Update Sarah Gordon and David Chess IBM Thomas J. Watson Research Center Yorktown Heights, NY Abstract This paper continues our examination of Trojan horses on the Internet; their prevalence, technical structure and impact. It explores the type and scope of threats encountered on the Internet - throughout history until today. It examines user attitudes and considers ways in which those attitudes can actively affect your organization’s vulnerability to Trojanizations of various types. It discusses the status of hostile active content on the Internet, including threats from Java and ActiveX, and re-examines the impact of these types of threats to Internet users in the real world. Observations related to the role of the antivirus industry in solving the problem are considered. Throughout the paper, technical and policy based strategies for minimizing the risk of damage from various types of Trojan horses on the Internet are presented This paper represents an update and summary of our research from Where There's Smoke There's Mirrors: The Truth About Trojan Horses on the Internet, presented at the Eighth International Virus Bulletin Conference in Munich Germany, October 1998, and Attitude Adjustment: Trojans and Malware on the Internet, presented at the European Institute for Computer Antivirus Research in Aalborg, Denmark, March 1999. Significant portions of those works are included here in original form. Descriptors: fidonet, internet, password stealing trojan, trojanized system, trojanized application, user behavior, java, activex, security policy, trojan horse, computer virus Attitude Adjustment: Trojans and Malware on the Internet Trojans On the Internet… Ever since the city of Troy was sacked by way of the apparently innocuous but ultimately deadly Trojan horse, the term has been used to talk about something that appears to be beneficial, but which hides an attack within. -

1 Evolution from 2G over 3G to 4G In the past 15 years, fixed line and wireless telecommunication as well as the Internet have developed both very quickly and very slowly depending on how one looks at the domain. To set current and future developments into perspective, the first chapter of this book gives a short overview of major events that have shaped these three sectors in the previous one-and-a-half decades. While the majority of the developments described below took place in most high-tech countries, local factors and national regulation delayed or accelerated events. Therefore, the time frame is split up into a number of periods and specific dates are only given for country-specific examples. 1.1 First Half of the 1990s – Voice-centric Communication Fifteen years ago, in 1993, Internet access was not widespread and most users were either studying or working at universities or in a few select companies in the IT industry. At this time, whole universities were connected to the Internet with a data rate of 9.6 kbit/s. Users had computers at home but dial-up to the university network was not yet widely used. Distributed bulletin board networks such as the Fidonet [1] were in widespread use by the few people who were online then. It can therefore be said that telecommunication 15 years ago was mainly voice-centric from a mass market point of view. An online telecom news magazine [2] gives a number of interesting figures on pricing around that time, when the telecom monopolies where still in place in most European countries. -

Both types of sources are growing dramatically in number and scope. This guide provides information on resources directly available to the researcher through electronic communications media. It includes enough technical information to get the user started. The use of ylectronic mail (e-mail) provides access to research and greatly :facilitates the research process. Two communications networks frequently used by academic institutions and researchers are BITNET and the Internet. Suggestions for using these and e-mail are given. A list is provided of computer discussion groups (facilitated by software known as Listserv) that may be of interest to researchers on women. Other tools that may be useful include news groups,different file distribution methods, Telnet, electronic conferencing, electronic journals, full-text databases, and numerical data sources.
