 Chapter 1 Introducing the NWA

NWA1000 Series User’s Guide

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.

• See 

 for instructions on changing your password.

• 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. 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 WPA2 user identification on your 
network so users must log in. This method is more common in business environments.   

• Hide your wireless network name (SSID). The SSID can be regularly broadcast and unauthorized 

users may use this information to access your network. See 

 for directions 

on using the web configurator to hide the SSID. 

• Enable the MAC filter to allow only trusted users to access your wireless network or deny 

unwanted users access based on their MAC address. See 

 for directions on 

configuring the MAC filter. 

Do the following things regularly to make the NWA more secure and to manage it more effectively.

• Change the password. Use a password that’s not easy to guess and that consists of different 

types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.
