Security
The Netopia R5000 Series Router 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.

Suggested security measures
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 R5000 Series Router 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
■When using AURP, accept connections only from configured partners.
■Configure the Netopia R5000 Series Router through the serial console port to ensure that your communications cannot be intercepted.
User accounts
When you first set up and configure the Netopia R5000 Series Router, 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.
