There are three areas
that need to be secured in any network: the
interior, the perimeter, and the exterior.
The interior is defined as the local network
itself, everything that is sheltered from
the outside world. This includes servers,
desktops, switches,
routers and other hardware and software attached
to the network; this also includes the media
the network uses to communicate, whether over
copper cable, fiber, or wireless. The perimeter
is the boundary between the interior network
and the outside world; this is typically a
connection to the Internet. The exterior consists
of business partners, branch offices, and
remote users that need access to the company's
interior network. Securing these three areas
should be a primary concern in any business.
Using an Intrusion Prevention
System (IPS) and monitoring network traffic
is a good start in keeping a network healthy
and safe. By having sensors throughout the
network to sort through traffic and identify
unusual activity, harmful actions can be stopped
prior to business disruption.
Securing the perimeter
of the network with a robust firewall with
continuosly updated firmware can prevent nearly
all external attackers from compromising a
company's network.
Securing remote access
is just as important as securing the network
interior; allowing insecure connections to
the network leaves an open back door to all
of the company's assets. By using virtual
private networks and the Secure
Desktop methodology these risks can be
avoided.

monitor and maintain Intrusion Prevention
Systems, firewalls and Virtual Private Networks
which increase network security without degradating
bandwidth and network resources. Choosing
CDS as your Network Security Partner allows
you to focus on your business and insures
network integrity.
