While such approaches may be perfectly feasible (and we do not wish to discourage creative use of technology), it is always worth considering whether the target population has access to the software required. People can only participate in a study if they have the appropriate software installed and configured, so an effective approach is to […]

Information Process
A merchant site that accepts electronic payments must include the following processing functions: (1) promotion; (2) welcoming; (3) payment; and (4) back-office.
Promotion
Successful implementation of a merchant site depends on a variety of factors, including site promotion. This can be done through fliers sent to the client or through fidelity programs. The promotion server can […]
JEPI (Joint Electronic Payment Initiative) is a joint initiative of the W3C and the CommerceNet consortium. The purpose is to allow a server to negotiate, with a client, the payment protocol advantageous to both parties. Membership of the JEPI project includes several suppliers of solutions for secure payments (Cybercash, GCTech), software (Microsof, IBM, OpenMarket), services […]
The proliferation of incompatible payment systems creates difficulties for all concerned — users, service suppliers, financial institutions, and regulatory bodies. History has shown repeatedly that the expansion of commerce requires a stable and uniform environment. Yet, in a single aspect of electronic commerce such as electronic purses, there are more than 20 commercialized schemes in […]
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 […]
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 […]
FTP is used to transfer files between computers. It is a complex protocol that enables the exchange of data files using different methods of data representation and file storage. In its simplest form, FTP uses clear-text username and password exchanges and is not considered to be a very secure utility. FTP was originally created when […]
Instead of trying to tackle the enormous job of developing still more applications to make it easier to integrate Unix and Windows into a cohesive network, Microsoft chose to take advantage of developments by other vendors and instead released the Windows NT Services for Unix Add-On Pack. This set of applications contains in-house applications developed […]
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 […]
In Version 1 of SFU, the password synchronization feature enabled you to configure a group of Unix servers so that when a user’s password was changed on a Windows NT server, the change was propagated to the user’s accounts on those target Unix servers. Because the application ran only on the Windows NT computer, it […]
An Infoworld test reported in the May 4, 1998 issue rated products as follows:
IBM’s outsourced solution using NetRanger
ISS Real Secure
Network Flight Recorder (NFR)
Abirnet Session Wall
The study by the Infoworld team announced a suite of 16 well-known network attacks that they tried against the products. Only NFR caught all of the attacks. The team used the […]
A number of other scanners are in the market today. Two others are mentioned here. The list of competitors is growing almost daily. Ballista, developed by Secure Networks, Inc., is now owned and marketed by Network Associates. The IBM Network Security Auditor (NS Auditor) is another alternative primarily for UNIX systems.
Ballista
Developed under the leadership […]
Many tradeoffs can be made in system monitoring. The two most important variables you can tradeoff are CPU and network performance. If you run Stalker Manager and Agent software on each node, you can analyze the data on the systems where it is created. You will spend CPU cycles on each node performing the analysis, […]
The worst thing you can do is make hasty decisions when you’ve been attacked. Know in advance what steps to follow. Quite simply, create a plan ahead of time. You can prepare your team for a security breach by adhering to the following guidelines.
Create an incident response team and assign specific responsibilities to team members. […]
Privacy
Privacy policies
In recognition of the increasingly strategic importance of privacy issues, in December 2000 IBM announced a new senior management position: Chief Privacy Officer. The company followed this appointment up in November 2001 with a large research initiative on privacy and the formation of an advisory body consisting of public- and private-sector representatives from a […]
Segmentation
Following completion of the marketing audit, the next step is to segment customers into specific categories. This process requires considerable market research and careful analysis, but it enables much more focused marketing efforts. The marketing plan should contain a paragraph explaining how customers are segmented, indicating which products or services are most suitable for each […]
