Security is one of the most pressing and expensive problems in the management of modern enterprise networks. The objective of this chapter is to persuade the reader to consider security from an entirely new perspective from the traditional one. We argue here that the current view of security management needs to be modified and propose a new business-friendly view that treats security as a process that is an integral part of network management and operations. For completeness, this article reviews some of the current security technologies and methodologies and examines which problems have been satisfactorily addressed and which still need a lot of research, development and operationalization. We finish with a brief overview of a current research project on automatic management of network security, which the author is involved in and addresses some of these issues.
