go through the firewall. The firewall examines each message and denies those that do not match
the security criteria or policies.
In some closed, or "default-deny" firewalls, all network connections are denied unless there is a
specific rule to allow the connection. To deploy this type of firewall, you must have detailed
information about the network applications required to meet your organization's needs. Other
firewalls allow all network connections that have not been explicitly denied. This type of open
firewall is easier to deploy, but it is not as secure.

The Firebox X Edge and Your Network

The Firebox® X Edge controls all traffic between the external network and the trusted network. The
Edge also includes an optional network interface that is separate from the trusted network. Use the
optional network for computers with "mixed trust. " For example, customers frequently use the
optional network for their remote users or for public servers such as a web server or email server. Your
firewall can stop all suspicious traffic from the external network to your trusted and optional networks.
The rules and policies that identify the suspicious traffic appear in "Firewall Policies" on page 91.
The Firebox X Edge e-Series is a firewall for small and remote offices. Some customers who purchase an
Edge do not know much about computer networks or network security. The Edge provides wizards
and many self-help tools for these customers. Advanced customers can use integration features to
connect an Edge to a larger wide area network. The Edge connects to a cable modem, DSL modem, or
ISDN router.
The web-based user interface of the Firebox X Edge lets you manage your network safely. You can
manage your Edge from different locations and at different times. This gives you more time and
resources to use on other components of your business.
