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.
