• TR-069. This is a standard that defines how your ZyXEL Device can be managed by a
management server.
1.3 Configuring Your ZyXEL Device’s Security Features
Your ZyXEL Device 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 ZyXEL Device. Follow the suggestions below to improve security on your ZyXEL
Device and network.
1.3.1 Control Access to Your Device
Ensure only people with permission can access your ZyXEL Device.
• Control physical access by locating devices in secure areas, such as locked rooms. Most
ZyXEL Devices 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 ZyXEL Device, such as the password used for
accessing the ZyXEL Device’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 ZyXEL Device’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 19 on page 247 for instructions on changing your password and setting the
timeout period.
• Configure remote management to control who can manage your ZyXEL Device. See
Chapter 17 on page 221 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.
1.3.2 Wireless Security
Wireless devices are especially vulnerable to attack. If your ZyXEL Device has a wireless
function, take the following measures to improve wireless security.
• Enable wireless security on your ZyXEL Device. Choose the most secure encryption
method that all devices on your network support. See Chapter 9 on page 127 for directions
on configuring encryption. If you have a RADIUS server, enable WPA(2) user
identification on your network so users must log in. This method is more common in
business environments.
• Use WPS’s PIN method to set up your wireless network instead of using the push-button
method. The PIN method is more secure than the push-button method as it ensures only
selected devices are added to your wireless network. See Section 9.5 on page 145 for more
information on using the WPS PIN method.
