This study investigates the impacts and risk assessment of technology-ena­ bled information (TET), v^hich are engaged in the process of discovering the opportunities and challenges presented by TEI to the new form of small medi­ um enterprises (SME) business transactions: Technology Enable Information Small Medium Enterprises (TEISME). Within the UK economy, the notion of TEISMEs is one that forms the focus for this research. Other technologies that enabled information are also discussed. For example electronic mail (e-mail), voice mail, facsimile machines (fax), teleconferencing, data conferencing, vid­ eo conferencing, electronic data interchange (EDI), and mobile phone (WAP), which are geared towards ease of transferring information are investigated. The electronic marketplace itself can be described as an on-line location for buyers and sellers to meet and conduct their business and complete transac­ tions. This study identified ways of minimising the risk liability of TEISME busi­ ness operations as a result of their dependences on TEI (Internet-eC). The rapid evolution and spread of information technology (IT) during the last few years is challenging SMEs, governments and the Internet security professionals to rethink the very nature of risk exposure. Parallel to this notion is the task of identifying: the technologies for Internet Security, the generic problems with network protocol layers, and key elements or threads that might be common to all TEISMEs business operations.

The open design of the Internet has not only opened many new opp- tunities for communications, but it has also opened many new avenues for attackers against organisations network and computing resources. This book is a critical investigation of the Internet Protocol Security (IPSec) based on combination of theoretical investigation and practical implementation, which provides an in-depth understanding of the IPSec framework. The bene?ts of IPSec were exploited while the delimiting factors cannot be ignored. Infor- tion security has become a major concern in recent times as more and more computers are being connected to the global Internet. With so much data tra- ferring over public networks, the risk of sensitive information has increased exponentially and the increase of Internet hosts continuously requires ad- tional security support. The IPSec may be used in three different security - mains: Virtual private networks, Application-level security, and Routing se- rity. It comprises of suite of protocols, which are developed to ensure that the integrity, con?dentiality and authentication of data communications over an IP network. The IPSec is predominately used in virtual private networks (VPNs). But when used in application-level security or routing security, the IPSec is not a complete solution and must be coupled with other security measures to be effective. As with other security systems, poor maintenance can easily lead to a critical system failure.
