 Chapter 1 Introducing the NWA

NWA1100-N User’s Guide

Use any of the following methods to manage the NWA.

• Web Configurator. This is recommended for everyday management of the NWA using a 

(supported) web browser.

• Command Line Interface. Line commands are mostly used for troubleshooting by service 

engineers.

• FTP (File Transfer Protocol) for firmware upgrades.
• SNMP (Simple Network Management Protocol). The device can be monitored by an SNMP 

manager.

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. 

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 

 for instructions on changing your password and setting the timeout 

period.

• Configure remote management to control who can manage your NWA. See 

 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.

Wireless devices are especially vulnerable to attack. If your NWA has a wireless function, take the 
following measures to improve wireless security.

• Enable wireless security on your NWA. Choose the most secure encryption method that all 

devices on your network support. See 

 for directions on configuring 

encryption. If you have a RADIUS server, enable IEEE 802.1x or WPA(2) user identification on 
your network so users must log in. This method is more common in business environments.
