Security 14-1

Chapter 14

Security

The Netopia R2121 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:

■“Suggested security measures” on page 14-1, lists actions for blocking potential security holes.

■“User accounts,” beginning on page 14-2, shows you how to set up name/password combinations to protect the Netopia R2121’s configuration screens.

■“Dial-in Console Access” on page 14-3

■“Telnet access” on page 14-4, shows you how to control access to the Netopia R2121 by those using the Telnet protocol.

■“About filters and filter sets,” beginning on page 14-4, and “Working with IP filters and filter sets,” beginning on page 14-12, have information on what filters are, how they work, how to customize them, and how to use them in sets. For information on IPX filters and filter sets, see “IPX filters,” beginning on page 14-22.

■“Firewall tutorial” on page 14-30

■“Token Security Authentication” on page 14-37

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 R2121 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.

■When using AURP, accept connections only from configured partners.

■Configure the Netopia R2121 through the serial console port to ensure that your communications cannot be intercepted.
