Networking, the communication between two or more networks, encompasses every aspect of connecting computers together. With the evolution of networking and the Internet, the threats to
information and networks have risen dramatically and performance has depleted enormously.
As a company grows its business its network design needs to be updated from the existing network
and expand it to accommodate additional users or workloads. But the diculty arises as networks
are being pressured to cost less, yet support the emerging applications and higher number of users
with increased performance. As personal, government and business-critical applications become
more prevalent on the Internet, it is imperative that all networks be protected from threats and
vulnerabilities in order for a business to achieve its fullest potential. Hence a Secure Design for a
network is critical in todays expanding corporate world.
