(fig.1) How a Firewall Works
*
Should bandwidth maximization occur due to the unlikely event of a customer’s server being compromised, the customer will incur no overage charges.
At Rackspace, we are committed to ensuring the security of your hosted solution. You store
valuable and confidential information on our equipment, so we offer a number of services to
guarantee that it stays secure. With highly qualified security engineers maintaining our network,
outstanding Cisco firewalls, our Firewall Control Panel and Intrusion Detection Systems and
our 1-Hour Hardware Replacement Guarantee, you are assured that Rackspace can provide
you with the security that you need.
No matter what level of security you require, a dedicated firewall is
an important first step in securing your hosted environment.
How It Works
A dedicated firewall acts as a protective barrier to keep destructive forces away from your
mission-critical data. A Rackspace Security Engineer assists you with making sure the rules you
need applied to our network are safe ones while still accomplishing your business need of
supplying public access to desired data. However, you establish and are the sole owner of the set
of rules that defines unwanted traffic. Based on this set of rules, information that is sent to your
server is inspected and then filtered

Additional Options
In addition to filtering traffic, our dedicated firewalls allow for a more secured form of communication with the implementation of a Virtual Private
Network (VPN). A VPN encrypts all information between designated hosts and your Rackspace environment. This is a useful tool for securely
extending your network across mobile users, business partners and corporate networks worldwide.
Why a Dedicated Firewall?
Unlike shared firewall devices that leave the possibility of unauthorized access by any other customer sharing the same firewall, a dedicated firewall
provides protection exclusively to your server, and ultimately, a greater level of security.* Additional options such as a VPN or a DMZ are not
available with a shared firewall.
Although a software firewall has its place, it does not offer the same level of security as a dedicated firewall. Because setting up a software firewall
can be tedious and complicated, a high level of user error is common and can create issues such as server shut-down, user lockout and system
vulnerability. These situations are avoidable with a Rackspace dedicated firewall.
