Editorial Pointers

Service-oriented computing adds a new layer to the Web services coverage we’ve presented in Communications—that is, its very foundation. In the past we’ve explored the technical challenges in providing goods and services in electronic, mobile environs; we’ve detailed the service interfaces and architectures for creating cross-platform interoperability; we’ve tackled the business and marketing hurdles in […]

Knowledge acquisition—a topic discussed frequently in this magazine in terms of the most effective ways for colleagues to share expertise and experience—is now being applied with a painful twist. A growing number of U.S. firms moving to outsourcing options expect their soon-to-be-pink-slipped tech employees to train their overseas replacements before they get the ax. The […]

Hal Berghel manages to write several pages about "The Discipline of Internet Forensics" (Digital Village, Aug. 2003) without ever addressing the purpose of forensic science as a whole. Fundamentally, it is science in the service of the law, and its main output is evidence sufficiently robust to withstand scrutiny in the courts. Such output must […]

Service-oriented computing (SOC) is the computing paradigm that utilizes services as fundamental elements for developing applications. SOC involves the service layers, functionality, and roles (see the sidebar “Services Overview”) as described by the extended service-oriented architecture (SOA) depicted in the figure here. Basic services, their descriptions, and basic operations (publication, discovery, selection, and binding) that […]

Information System Security Redux

Last month we discussed risks in trusting entities that might not actually be trustworthy. And yet, people use flawed systems that may cause more security and reliability problems than they solve. There are various reasons why untrustworthy mass-market software might be used so extensively, even if the source code is proprietary and the vendor can […]
