Security
The access point is configured by default as an “open system,” which broadcasts a
beacon signal including the configured SSID. Wireless clients with an SSID setting
of “any” can read the SSID from the beacon and automatically set their SSID to
allow immediate connection to the nearest access point.
To improve wireless network security, you have to implement two main functions:
• Authentication: It must be verified that clients attempting to connect to the network
are authorized users.
• Traffic Encryption: Data passing between the access point and clients must be
protected from interception and eavesdropping.
For a more secure network, the access point can implement one or a combination of
the following security mechanisms:
• Wired Equivalent Privacy (WEP)
page 6-70
• IEEE 802.1X page 6-84
• Wireless MAC address filtering page 6-13
• Wi-Fi Protected Access (WPA or WPA2) page 6-79
Both WEP and WPA security settings are configurable separately for each virtual
access point (VAP) interface. MAC address filtering, and RADIUS server settings
are global and apply to all VAP interfaces.
The security mechanisms that may be employed depend on the level of security
required, the network and management resources available, and the software
support provided on wireless clients.
