Today, and increasingly in the future, organizations use computing and intelligent networking infrastructure as a critical resource. Businesses allow transactions via the Internet/www to reach a worldwide audience at a relatively low cost. Due to the very advantages it provides, however, the Internet poses a unique set of vulnerabilities which need to be addressed. In fact, security is identified as the most important issue relative to the progress of e- business. It is critical from the viewpoints of both providers and customers. Thus, today's e-business services must include solutions that provide security as a primary component in their design and deployment.

This three-hour tutorial will provide an overview of e-business security needs and requirements. A general introduction to the field of security, covering services, mechanisms, as well as design principles, and practical examples of how to integrate security services into e-business will be discussed. Security vulnerabilities, threats, and countermeasures will be explained by presenting a few examples of security attacks and the corresponding safeguards.

Target Audience: The potential audience of this tutorial includes researchers and practitioners in network management as it relates to IP-based communications networks. A basic understanding of network management concepts, SNMP, and CLI is expected. The tutorial is designed for an intermediate level audience, although participants of any level should be able to derive value from it.


Rapid advances in networking technologies are changing the way we manage IP networks. Previously, network vendors focused on building boxes whose main features were to switch or route traffic as fast as possible. Management is based largely on CLI, designed specifically with human users in mind, and SNMP with a proliferation of thousands of special-purpose MIBs. Today as the Internet is transforming the IP networks into a global business service creation platform, this paradigm runs increasingly into limitations. While current initiatives such as policy-based management and CIM/DEN are elevating the scope of the management applications to beyond network element and stovepipe focus, little attention has been paid to manageability of the network infrastructure itself and the needs to evolve management instrumentation.
This tutorial presents a view of the IP network management problem from the perspective of the network itself. It focuses on how to address enhanced manageability requirements in the network infrastructure. This includes what can and should be instrumented inside a network element, and what can and should be instrumented with a scope that goes beyond the individual network element to result in more general "manageability services" provided by the network. We will discuss the relevance of manageability as a business driver and provide an in-depth analysis of the various factors that contribute to manageability. After this, techniques will be presented that can be applied to enhance manageability, also in light of increased focus on applications such as on-demand services, managed services, and plug-n-play networking. We will also discuss the role of certain technologies such as XML or Netflow in the emergence of a new generation of management interfaces. Finally, scenarios will be used to illustrate how the resulting advances in manageability facilitate not only the development of management applications, but ultimately result in networks that are more autonomous and less complex and costly to manage than the norm today.
