Introduction

Today effective security network control is declining due to de-perimeterization, an emerging term used to describe the erosion of the enterprise firewall as a single point of control due to many trends including workforce mobility, smarter mobile devices, business partnerships, wireless access, Service Oriented Architecture (SOA) and Software as a Service (SaaS).

New technologies, products and services, customers, and user behaviors will continue to drive significant changes to our enterprise network infrastructures and its management.

Some of the more significant Enterprise trends that will continue to pose challenge to the Corporate Enterprise Network include:

1. Externalization: Use of IT products and services outside of the enterprise
2. Consumerization: Desire of individuals to choose personal devices / services / apps
3. Democratization: Rise of social networks within / external to the enterprise
4. Business Process Transformation: Aligning Corporate people, process and technology initiatives more closely with the Corporate business strategy and vision.
