Nevertheless, the transformation of the county fair into a supermarket is taking longer than originally anticipated. Use of the Internet for economic exchange clashes with the culture of freely available information, absence of a central authority, and the legitimate concerns regarding the security of information on the network. Security on the Internet is an afterthought; […]
The arguments in favor of the Internet sound, at a decade interval, like an echo of those that were previously formulated in praise of the Minitel. This passion for information technology is displayed in a context where ambitious growth rates are not physically sustainable, due to market saturation in rich countries, the progressive depletion of […]
The automation and dematerialization of monetary exchanges are not objectives per se, but are solely means to improve the productivity of financial institutions. In this regard, an overabundance of standards, and sometimes their competition, may constitute a barrier to the establishment of electronic commerce. Even if some manufacturers think they can profit from this situation, […]

How Legal Wire tapping Works
CALEA requires that communications providers allow law enforcement officials to be able to listen in on phone conversations and get information about those phone calls, but only when the law enforcement agency has gotten approval for the tap.
The law enforcement agency goes before a judge and presents reasons a wiretap is […]
Throughout the history of the United States, one of the greatest political tensions has been that which balances personal privacy against the need for law enforcement to protect individuals and the country as a whole.
That tension has been with us from the very earliest days of the Republic. The Founding Fathers were extremely cognizant of […]
Not all devices are equipped with SNMP capabilities. For these devices, another device might be able to handle those functions and acts as a proxy agent so that it can still be managed from the SNMP management console. For example, a network card might not be SNMP-enabled, but the host computer can run a process […]
Just as in a large corporate network, you might have a problem with one or more components that make up the network. Network cards go bad, as do hubs and switches (and even individual ports on a hub or switch). Always keep handy the minimal documentation that comes with your computer(s), network card, hub, switch, […]
Windows operating systems now support many protocols and utilities that were originally created for the Unix Environment. The first that comes to mind, and perhaps the most important, is the TCP/IP protocol suite. This includes not just the TCP/IP protocols, but other associated protocols and utilities.
Many of the technologies that began in the Unix world […]
Although Unix and Linux can be considered close cousins, trying to find similarities between them and Novell NetWare is not an easy job. Unix/Linux and NetWare systems are very different from each other, so when you’re considering a migration from one to the other, or integrating the two into a heterogeneous network, it requires some […]
A pattern-matching IDS can look at a sequence of events to detect a problem. For example, if someone is suddenly removing dozens or hundreds of files, you might be faced with a disgruntled employee about to leave a system in an irreparable state. If you wanted to detect such an attack, you could configure your […]
A network IDS works by running a network adapter in promiscuous mode to capture all of the packets coming into and going out of a particular subnet. Notice that this is not the same as watching all of the network traffic that appears on a subnet. Look at Figure 9.2. Here, the physical arrangement of […]
Mobile technologies are not new; it has been possible for many years to access the Internet for e-mail using a laptop connected via a modem. With the ongoing convergence of devices, we are now seeing a range of hybrid devices combining PDA features such as calendar, address list, task list and office tools with phone […]
These approaches seek to prove the sender of the e-mail is legitimate — that senders are who they say they are. The SMTP standard used for e-mail allows any computer user to send e-mail claiming to be from anyone, so its easy for spammers to send e-mails from forged addresses. Authentication uses different methods, which […]
The E-wallet Wars
Shoppers wanting to get their caffeine fix online at www.starbucks.com now have only one path to take when they pay for their beans. If they are already registered with Passport, Microsoft’s new identity-verification program, they can use it to complete their purchase. If not, they are directed to a site where they can […]
IntElegant’s CXO co-founded En Vivo, which IntElegant acquired in 1999. He described En Vivo as a “research and development consultancy for understanding experience, and turning that into a basis for product, service, and communication development.” En Vivo worked closely with new-product design groups at client companies, many from the package goods, appliance, and automotive industries. […]
Go Beyond Old-Style Purist Approaches To Attending To Usability
Standard recipes of attending to “usability” will often be inadequate to specific organizations, projects and contexts. Plus, some of our most valuable work extends beyond usability — including using customer-centered activities early so that we contribute to business strategy and plans, and extending concept and design research […]
Leung and Antypas (2001) note how the current mobile landscape resembles the first-generation Internet in the mid-1990s in terms of the key business challenges:
Bandwidth. Many innovative services such as real-time video streaming will not be feasible, given the limited bandwidth currently available, and will remain what the authors refer to as ‘pipe dreams’ for the […]
