Netopia 4741 2a4na ユーザーガイド

The Netopia 4741 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.

This section covers the following topics:

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 4741 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.

■

Set the answer profile so it must match incoming calls to a connection profile.

■

Leave the Enable Dial-in Console Access option set to No.

■

When using AURP, accept connections only from configured par tners.

■

Configure the Netopia 4741 through the serial console por t to ensure that your communications cannot be 
intercepted.

When you first set up and configure the Netopia 4741, no passwords are required to access the configuration 
screens. Anyone could tamper with the router’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.
