AirPort Security
This chapter provides an overview of the security features
available with the AirPort Extreme Base Station and
AirPort Express.
Apple has designed the AirPort Extreme Base Station and AirPort Express to provide
multiple levels of security, so you can enjoy peace of mind when you access the
Internet, manage online financial transactions, or send and receive email. The AirPort
Extreme Base Station also includes a slot for inserting a Kensington lock to deter theft.
For information and instructions for setting up these security features, see “Setting Up
the AirPort Network” on page 17.
Security for AirPort Networks at Home
Network attacks can occur through wireless as well as wired networks. Apple gives you
ways to protect your entire AirPort network as well as the data that travels over it.
Firewall
You can separate your wireless network from the outside world with firewall protection.
The AirPort Extreme Base Station and AirPort Express have a built-in firewall that
creates a barrier between your network and the Internet, protecting data from Internet-
based IP attacks. The firewall is automatically turned on when you set up the base
station to share a single Internet connection. For computers with a cable or DSL
modem, AirPort can actually be safer than a wired connection.
Closed Network
Creating a closed network helps keep the network name and the very existence of your
network private. The network will not show up in a scan of available networks, so
prospective users of your network must know the network name and password to
access it.
