The Netopia D-Series provides a number of security features to help protect its configuration screens and your 
local network from unauthorized access. Although these features are optional, it is strongly recommended that 
you use them.

In addition to setting up user accounts, Telnet access, and filters (all of which are covered later in this chapter), 
there are other actions you can take to make the Netopia D-Series and your network more secure:
Change the SNMP community strings (or passwords). The default community strings are universal and 
could easily be known to a potential intruder.
Configure the Netopia D-Series through the serial console por t to ensure that your communications cannot 
be intercepted.

When you first set up and configure the Netopia D-Series, no passwords are required to access the 
configuration screens. Anyone could tamper with the Netopia D-Series’s configuration by simply connecting it to 
a console.
However, by adding user accounts, you can protect the most sensitive screens from unauthorized access. User 
accounts are composed of name/password combinations that can be given to authorized users.
Caution!
You are strongly encouraged to add protection to the configuration screens. Unprotected screens could allow an 
unauthorized user to compromise the operation of your entire network.
Once user accounts are created, users who attempt to access protected screens will be challenged. Users who 
enter an incorrect name or password are returned to a screen requesting a name/password combination to 
access the Main Menu.
