Configuration
Security
This section discusses configuration options
that restrict configuration.
Overview
The gateway uses the industry standard IP protocols. Since IP
is a well-known standard, its security vulnerabilities are also
well known and may be exploited. Several gateway options are
available to enhance the inherent security of your network.
However, since network security is a moving target and
absolute security is never achievable, every network installation
should be designed and implemented with care to minimize
security risks in a way that is appropriate for the application
and perceived risks.
The gateway may be configured with several levels of security
configuration and authentication. These restrict the ability of
an unwanted user from changing the configuration of the
gateway. They do
not restrict the ability of a remote device to
deliver packets to the gateway’s data port.
At the level 0, any workstation may be used to configure the
gateway via either telnet or web browser configuration. Level 1
