The worldwide scope of an electronic commerce offer must rely on a set of physical and logical solutions to meet users’ expectations. Not all customers are computer wizards, and the architecture must account for ergonomic factors, in addition to the security of the exchanges and the different methods for accessing the telecommunications network.

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 […]
If you ask a typical consumer about wireless communications, you might hear about Wi-Fi or wireless Ethernet, but it’s just as likely that cell phones, smartphones, or PDAs with onboard wireless networking would also be part of the conversation. These devices offer web browsing, email, video and still image capture, and text messaging, and they […]
One of the main concerns of network administrators in the 1980s was that any person in the company network could easily install a modem in her computer and connect to computers outside the network. For digital telephone systems, this was not a problem. But for small businesses using an analog telephone system, this could present […]
Other Bluetooth Profiles
Bluetooth 1.x and 2.0 specifications provide for several others. More profiles are expected to be added if the technology is accepted by the marketplace as a solution for short-distance cable replacement. Many of the following profiles are still in draft format and are not yet considered to be standards that all Bluetooth vendors […]

Creating an Address Scope
After you have authorized a server on the network, you can create a scope of addresses that the DHCP server can administer to clients. From the MMC utility, click once on the server you want to administer, and then select New Scope from the Action menu. The New Scope Wizard pops up. […]
The first directory that comes to mind when you think of early computer systems is the file system directory. The organization of data files and programs into a structure of directories and subdirectories became more important as the size of the available storage grew. When networking PCs became a necessity, the capability to organize users […]
The Point-to-Point Protocol (PPP) is an error-checking protocol used for dial-up connections to the Internet. PPP allows for the encapsulation of data packets from multiple protocols for simple transmission across a dedicated link, such as a phone line when you dial in to the Internet. PPP performs no routing functions, but merely encapsulates the protocol […]
Has This Happened Before—What Is the Procedure to Follow?
Keeping track of how problems were solved will keep you from expending a lot of effort solving the same problem again and again. Using documentation that enables a quick lookup of information based on symptoms can help you find older problem reports or perhaps standard help-desk documentation […]
A logical map of the network shows the relationships between components and the flow of information through the network. A physical map of the network tries to approximate on paper a representation of how each component of the network is connected to the network. For example, a logical map for a Windows network might show […]
The newest, latest, and maybe greatest approach to SOHO networking environments is to remove the cables altogether. It’s now quite inexpensive to buy a small wireless Access Point (AP) and install wireless network cards in the computers in your small or home office. This allows you, for example, to use a laptop and take it […]
Just as you need to test new network configurations or PC configurations in a laboratory before rolling them out for production usage, you need to evaluate the placement of APs should you decide to get into wireless networking. Wi-Fi provides for roaming capabilities, but it also enables you to restrict users to selected APs if […]
Perhaps as a security officer, you day dream about spending endless hours tracking down and catching intruders. You envision yourself being rewarded by company executives for heroic actions and ingenuity, which led to the recover of important intellectual property or money. And, you do all of this in a few long nights and still have […]
Develop an effective communication plan. Decide what types of events require you to notify local law enforcement, the FBI, other sites, and coordinating bodies like those identified in the Appendix. Decide in advance what types of events require you to notify as many people as possible and which incidents demand secrecy. If you suspect an […]
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 […]
Producing a plan for retention encourages a long-term view of the aims for our campaigns, and enables them to reinforce each other rather than their being isolated. To build a retention plan, work towards building a communications timeline for the next 6, 12 or 18 months. This helps to form a picture that shows the […]
Codes of conduct
Computer Professionals for Social Responsibility (1996) suggest that:
Each employer should provide and act on clear policies regarding the privacy implications of the computing resources used in the workplace. The policies should explicitly describe:
Acceptable use of electronic mail and computer resources, including personal use;
Practices that may be used to enforce these policies, such as […]
