• SMT. System Management Terminal is a text-based configuration menu that you
can use to configure your device. Use Telnet to access the SMT.
• FTP. File Transfer Protocol for firmware upgrades and configuration backup and
restore.
• SNMP. The device can be monitored by an SNMP manager. See the SNMP
chapter (Section 16.7 on page 194) in this User’s Guide.
1.5 Configuring Your NWA’s Security Features
Your NWA comes with a variety of security features. This section summarizes
these features and provides links to sections in the User’s Guide to configure
security settings on your NWA. Follow the suggestions below to improve security
on your NWA and network.
1.5.1 Control Access to Your Device
Ensure only people with permission can access your NWA.
• Control physical access by locating devices in secure areas, such as locked
rooms. Most NWAs have a reset button. If an unauthorized person has access to
the reset button, they can then reset the device’s password to its default
password, log in and reconfigure its settings.
• Change any default passwords on the NWA, such as the password used for
accessing the NWA’s web configurator (if it has a web configurator). Use a
password with a combination of letters and numbers and change your password
regularly. Write down the password and put it in a safe place.
• Avoid setting a long timeout period before the NWA’s web configurator
automatically times out. A short timeout reduces the risk of unauthorized
person accessing the web configurator while it is left idle.
See Chapter 7 on page 109 for instructions on changing your password and
setting the timeout period.
• Configure remote management to control who can manage your NWA. See
Chapter 16 on page 187 for more information. If you enable remote
management, ensure you have enabled remote management only on the IP
addresses, services or interfaces you intended and that other remote
management settings are disabled.
1.5.2 Wireless Security
Wireless devices are especially vulnerable to attack. If your NWA has a wireless
function, take the following measures to improve wireless security.
