BaySecure FireWall-1
BaySecure™ FireWall-1 builds firewall security features into Bay Networks router
software. It does this by integrating the statef ul inspection module from Version
2.1 of the Check Point Software Technologi es FireWall-1 software into the Bay
Networks router operating system of Bay Networks BN
routers. BaySecure FireWall-1 provides all of the security features from Version
2.1 of the Check Point Software Technologi es FireWall-1 software, except for
user authentication, address translation, statistics and encryption.

Managing Firewall Operation
A firewall is the hardware and/or software that limits the exposure of a computer
or network to an invasion from an external source. To control the operation of the
firewall on the router , you use the Check Point FireWa ll-1 management software.
You install this management software on either a computer runnin g
Windows NT or on a UNIX workstation to create a firewall management station.
From the management station, you can use the FireWall-1 management software
to define a security policy and download it to the router. The security policy
specifie s how the firewa ll operates. For instructions on how to install the
FireWall-1 management software, see Chapter 2
Management Software.” To learn how to configure a security polic y, see your
Check Point documentation .

Configuring BaySecure FireWall-1
How the Firewall Software Works
The stateful inspect ion module in the Bay Networks router software inspects all
data packets traveling betwee n the data link a nd network la yers an d communica tes
the results to the management station. If the data packets meet the security
requirements specified in the security policy, the router forwards the data. If the
data packets violate the security policy, the route r drops the data packe ts, and logs
the information to the management station.
