Network and computer security continues to be one of the hottest topics in the industry today. And no wonder; once connected to the Internet, an organization cannot make a move without considering the security aspects, particularly compelling as the number of security incidents continues to increase. Electronic commerce, virtual private networks (VPNs), cable modems and ADSL, voice over IP, even merely browsing the Web all have security implications. This tutorial will cover a broad range of network security topics, focusing on timely, relevant issues. It will define terms and concepts related to cryptography, viruses, Java/Active-X, security levels ("what does C2-level protection really mean?"), VPNs and tunneling protocols, IPsec and other secure protocols, and firewalls. Attendees will leave with a number of action items that can be brought back to the network!
This is an intermediate-level tutorial, assuming knowledge of computer, operating systems, network protocols, TCP/IP, and LAN/WAN topologies.

Virtual private networks is largely a solution to a major corporate need — secure ubiquitous connectivity. A VPN transforms the Internet into a global private network over which secure business and commerce can be conducted. This talk introduces VPNs addresses the various technical issues in building and maintaining them.

The goal of this tutorial is to present a comprehensive survey of developments in the area of Quality of Service (QoS) provisioning in the Internet. It will discuss issues related to providing end-to-end QoS for real-time multimedia communications over the Internet. End system as well as networking issues will be discussed. The standards and protocols will include Real-time Transport Protocol (RTP), Resource Reservation Protocol (RSVP), Integrated and Differentiated Service models of IETF and mapping of these services to specific link layers. An overview of new developments in QoS routing research and protocols such as Multiprotocol Label Switching (MPLS) will be presented. Experimental Evaluation and simulation results based on Berkeley NS Simulator will also be presented. Commercial efforts by different software (e.g. QoS API) and router/switch products supporting QoS will be included.
This tutorial is targeted for software developers and researchers who need to understand the QoS issues and the current state-of-the-art, network engineers/designers/managers who need to understand how to implement, maintain, and deploy QoS technologies, and graduate and senior students working in this area.
