AirPort Security
Password Protection and Encryption
AirPort uses password protection and encryption to deliver a level of security
comparable to traditional wired networks. Users can be required to enter a password to
log in to the AirPort network. When transmitting data and passwords, the base station
uses up to 128-bit encryption, through either Wi-Fi Protected Access

log in to the AirPort network. When transmitting data and passwords, the base station
uses up to 128-bit encryption, through either Wi-Fi Protected Access
™
(WPA) or Wireless
Equivalent Privacy (WEP), to scramble data and help keep it safe.
Note: WPA security features are available only to AirPort Extreme Base Stations; AirPort
Express; AirPort and AirPort Extreme clients using Mac OS X 10.3 or later and AirPort 3.3
or later, and to non-Apple clients using other 802.11 wireless adapters that support

If you’re using AirPort in conjunction with an America Online account, you can use AOL
parental controls to further restrict access. The settings you configure are used for all

Security for AirPort Networks in Business and Education
Businesses, schools, colleges, and universities want to restrict network communications
to authorized users and keep data safe from prying eyes, so AirPort Extreme hardware
and software provide a robust suite of security mechanisms. Use AirPort Admin Utility
to set up these advanced security features.

Transmitter Power Control
Because radio waves travel in all directions, they can extend outside the confines of a
specific building. The Transmitter Power setting in AirPort Admin Utility lets you adjust
the transmission range of your base station’s network. Only users within the network
vicinity have access to the network.

MAC Filtering
Every AirPort and wireless card has a unique MAC address. For AirPort and AirPort
Extreme Cards, the MAC address is sometimes referred to as the AirPort ID. Support for
MAC (Media Access Control) filtering lets administrators set up a list of MAC addresses
and restrict access to the network to only those users whose MAC addresses are in the
access control list.
