Security Issues
Much has been publicized in the mass media recently about security problems with wireless LANs.
Although it cannot be denied that some encryption algorithms currently used in 802.11 are flawed, the
fact is that security breaches of a wireless LAN require a deliberate attempt to access the network by an
intruder.
The primary issue is that many current users of wireless LAN have opted NOT to turn on security
features. If users were to enable the security features currently available (including only allowing known
systems access to the network and enabling WEP [Wired Equivalent Privacy] or WPA [Wifi Protected
Access]) on even the most basic access points, the intruder's work is much harder. Much as a burglar
will stray away from a house whose doors and windows are securely locked, so too will an attacker tend
to move past a wireless network when even the simplest security measures are enabled.
Encryption and Authoriztion Algorithm Overview
Before setting up any kind of wireless infrastructure or installing new devices within an existing site, it is a
good idea to fully understand the technology. Please refer to the Encryption & Algorithm Overview at
the end of this manual for a brief explanation of wireless security terms and how they relate to the
MT7570 and other AML products.
