Справочник Пользователя для Netopia R310

The Netopia R310 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:

■

, lists actions for blocking potential security holes.

■

, shows you how to set up name/password combinations to 

protect the Netopia R310’s configuration screens.

■

■

, shows you how to control access to the Netopia R310 by those using the 

Telnet protocol.

■

, have information on what filters are, how they work, how to customize them, and 

how to use them in sets.

■

■

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 R310 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.

■

Use CallerID.

■

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

■

Where possible, insist on using PAP, CHAP, or secure authentication token card to authenticate 
connections to and from connection profiles.

■

In high risk areas, configure the Netopia R310 through the serial console por t to ensure that your 
communications cannot be intercepted.

When you first set up and configure the Netopia R310, no passwords are required to access the configuration 
screens. Anyone could tamper with the router’s configuration by simply connecting it to a console.
