According to Edward Yourdon, software development may soon move out of the U.S. into software factories in a dozen countries unless U.S. software organizations exploit the key software technologies examined in this new publication. Here Mr. Yourdon takes a close look at how U.S. companies can implement object oriented methods, CASE tools, software quality assurance, structured methods, software metrics, and re-engineering.

Internet-based telephony is an exciting prospect for every company running a TCP/IP stack network. But is won't be simple to deploy. Unlike traditional packet networks, IP networks are connectionless and pose entirely different engineering challenges. This book explores the potential investment in terms of both money and technology. It provides a review of important IP support protocols, detailed descriptions of voice-over-IP technologies, and case studies of Internet telephony servers.

Commerce over the Internet will be the wave of the future, provided businesses can allay consumer fears about security. Up until now, most security efforts have focused on protecting the actual transaction while neglecting the other components necessary for secure commerce. Yet if any one component is vulnerable, the transaction remains at risk. Written by a security expert, this book addresses the four essential elements of safe electronic commerce: the data transaction, the servers, the clients, and the host networks. It covers in detail the steps required to insure that each is truly secure.

Using non-technical language, this book shows how the two leading encryption programs on the market PGP (Pretty Good Privacy) and PEM (Privacy Enhanced Mail) can be used to vastly enhance the security of computer communications. It also evaluates the security systems of many popular commercial e-mail products, including Lotus cc:mail, Microsoft Mail, and others.
