Security

Netopia Firmware Version 8.7 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.

• “Conﬁguration Management” on page 10-46

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 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.
