The Future of Networks and Network Security

Abstract

Networks are evolving rapidly into huge, omnipresent, multiservice entities. They are connected worldwide into an Internet that has many different administrations, purposes, resource owners, and users. As the network grows, design parameters are exceeded and new vulnerabilities are introduced. Network security solutions must accommodate enormous changes in the network itself, in the network security requirements, and in the mechanisms and constraints that drive appropriate security mechanisms. As the network serves a larger and more diverse group of users, multiple, flexible security approaches will be necessary to meet their requirements.
